Best for:
Adding retention to Prometheus servers you keep
Pros:
- Nothing about your existing setup changes: the same servers, collectors, and configuration files keep running, which is why it is the lowest-risk option here.
- Removing duplicates across a redundant Prometheus pair closes the gap in the data that appears when one of the two goes offline.
- Every component is open source, with no capability held back for a paid tier.
- No single company controls the project, which matters to teams that weigh governance in the decision.
Cons:
- Querier, Store Gateway, Sidecar, and Compactor are four separate processes to deploy, configure, and monitor.
- The sidecar requires turning off Prometheus's own data compaction, which can slow Prometheus down and raise its memory use.
- Queries covering long time ranges spread across multiple Store Gateway instances, so historical queries get slower as retention grows.
- There is no vendor and no rate card, so all operational risk and all support sit with your team.

Pros:
Cons:
Relative cost:
Community Edition free (self-hosted); Teams $49/month; Enterprise from $4,000/month; usage-based beyond plan limits
SigNoz
Pricing

Best for:
Querying telemetry with SQL
Pros:
- Containers starting and stopping no longer create a capacity risk, because the engine has no cardinality limit to exhaust.
- Parquet is an open file format, so stored telemetry stays readable by other tools rather than locked behind one vendor's API.
- Existing Prometheus servers forward data after a one-line configuration change, so ingestion can move before any queries do.
- SQL puts telemetry within reach of anyone on the team who already queries the data warehouse.
Cons:
- PromQL isn't supported, so every existing dashboard and alert rule must be rewritten.
- A single-machine deployment has no built-in redundancy or replication.
- Flux, the query language in version 2, is gone from version 3, so InfluxDB 2.x users face a rewrite whichever platform they choose.
- Three query languages across three major versions is a poor record for a system you plan to keep for years.
InfluxDB 3
Pricing
Best for:
Cloud-native, DevOps teams
Pros:
- Comprehensive observability across the entire technology stack
- Excellent support for containerized and cloud-native environments
- Strong API and integration ecosystem
- Advanced analytics and machine learning capabilities
- Scalable SaaS delivery mode
Cons:
- Premium pricing that can escalate quickly with increased data volumes and additional modules
- Complex cost structure making budget forecasting challenging for growing organizations
- Resource consumption from agents that may impact endpoint performance in some environments
- Data retention limitations on lower tiers affecting long-term compliance and analysis needs
- Vendor lock-in concerns due to proprietary data formats and extensive system integrations

New Relic
Pricing

Best for:
Automatic root-cause analysis at enterprise scale
Pros:
- Dependency and topology mapping happens automatically, giving responders a live map of service relationships nobody had to draw.
- Automatic discovery covers large estates that would take months to instrument by hand.
- Real-user data sits beside backend traces, so a slow page traces back to the service causing it.
- Charges are based on consumption rather than seats, so the bill does not grow as more people get access.
Cons:
- Practitioners report OneAgent adding latency on high-traffic services, and containers failing with obscure loader errors that are hard to diagnose.
- Instrumenting hundreds of applications with a proprietary agent makes removing it later a significant engineering project.
- Davis AI can over-alert once its customization options run out, producing the noise it exists to remove.
- Consumption-based metering is hard to forecast, which is the most cited procurement friction.
Dynatrace
Pricing

Best for:
Cost-conscious enterprises
Pros:
- Zero licensing costs for unlimited devices and users
- Highly customizable with deep configuration options
- Strong scalability for large, distributed environments
- Rich visualization and reporting capabilities
- Regular updates and an active development community
Cons:
- Complex initial setup and configuration requiring technical expertise

Dimitri Cabete Jorge, Co-Founder & CTO · Last updated: August 2026 · Facts verified: August 2026
TL;DR: Prometheus keeps its data on a single machine with no replication, and deletes anything older than 15 days unless you change the default. Both limits start to hurt as the number of monitored machines grows. VictoriaMetrics is the closest thing to a drop-in swap: existing collectors and Grafana dashboards keep working after the storage engine changes, though alerts built on the rate() function need retesting. Grafana Cloud is the closest managed equivalent, because its Mimir backend runs the same query language. Fully managed platforms offer that compatibility in exchange for metrics, logs, and traces in one place, plus AI-assisted incident triage. Siit is the AI Service Desk for the access and admin requests a monitoring stack generates, so it sits beside this decision rather than inside it.
How We Evaluated Prometheus Alternatives
Every tool here had to work as a Prometheus replacement or extension for metrics, which ruled out log-only and trace-only products. We then compared each on four things. First, compatibility with PromQL, the query language every Prometheus dashboard and alert rule is written in. Then the team each tool fits, the published starting price, and any available peer-review rating. PromQL carries the most weight, because it decides whether a migration means swapping one component or rewriting every dashboard and alert your team owns. The same lens applied to the surrounding toolchain appears in our integrated tooling roundup.
Prometheus Alternatives at a Glance
PromQL support splits the field cleanly. VictoriaMetrics, Grafana Cloud, and Thanos run your existing dashboards and alert rules as-is. The managed platforms below them accept Prometheus data but query it in their own language, which turns a migration into a rebuild.
Four entries carry no usable peer-review score rather than a weak one. G2 flags its own VictoriaMetrics listing as having too few reviews to guide a buying decision, SigNoz has no G2 or Capterra product rating, and no peer-review score is available for Thanos or InfluxDB 3. Treat that absence as procurement information, not a gap in the research.
If protecting your existing dashboards and alerts is the priority, start with VictoriaMetrics, Grafana Cloud, or Thanos. If you are consolidating tools and accept rewriting queries, start with Datadog, New Relic, or Dynatrace.
VictoriaMetrics
VictoriaMetrics is an open-source time-series database built as a drop-in replacement for Prometheus. It is designed for high cardinality, meaning a very large number of distinct label combinations, which is what breaks Prometheus first in container environments. It serves teams that have hit Prometheus's memory ceiling and want to change the storage engine without rebuilding the collectors and dashboards around it.
VictoriaMetrics Key Features
- MetricsQL queries: MetricsQL accepts PromQL syntax, so Grafana dashboards pointed at a Prometheus data source keep working after the switch.
- vmagent collector: A replacement for Prometheus's own collection process that uses less CPU, memory, and disk when pulling from more than 1,000 targets.
- Single binary or cluster: One executable covers small setups. Cluster mode adds multi-tenancy and replication when one machine is no longer enough.
- OpenTelemetry Protocol (OTLP) ingestion: Accepts data in the vendor-neutral OpenTelemetry format, so a Collector can write to the same backend as your Prometheus collectors.
VictoriaMetrics Pros and Cons
Pros:
- The vendor's own benchmarks report 1.7 to 5 times lower memory use than Prometheus, depending on workload. There are also no memory spikes every two hours, which is when Prometheus compacts its data.
- The vmctl tool imports Prometheus snapshots, so years of history move across instead of starting from an empty database.
- Label churn from containers starting and stopping no longer risks the out-of-memory crashes that take Prometheus down.
- Both the single-machine and cluster versions are Apache 2.0 licensed, so scaling up does not trigger a licensing conversation.
Cons:
- The single-machine version has no replication, so durability depends entirely on the underlying disk.
- The rate() function calculates from actual timestamps where Prometheus estimates between them, so alerts built on rate() can fire at different points after migration.
- There is no dashboarding beyond basic charts, so Grafana stays in the stack either way.
- Peer-review evidence is thin, which matters if procurement requires third-party validation before signing.
What Users Say About VictoriaMetrics
Reddit and Hacker News carry the useful migration reports here, because G2 and Gartner Peer Insights have too few reviews to read.
- Kubernetes operators report using roughly 60% less disk than their previous Prometheus setups, with faster queries.
- Operators describe the built-in redundancy as simpler to run than Thanos.
- Teams running it for a year or more report it stays up without intervention, including one that replaced five Prometheus servers consuming 30 to 40 GB of memory per cluster.
- Complaints target rough documentation and a small community, plus licensing uncertainty that the company's CTO settled by confirming Apache 2 in August 2024.
User sentiment sourced from Reddit and Hacker News as of April 2025.
VictoriaMetrics Pricing
- Open source: free under Apache 2.0, in both single-machine and cluster form.
- Cloud single-node: listed at $225 per month for up to 500,000 active time series with one month of retention.
- Cloud cluster: listed from $1,300 per month.
- Fees and billing: Cloud usage is metered hourly against fixed capacity tiers rather than per host, and new accounts get $200 in credits valid for 30 days.
Pricing from VictoriaMetrics' Cloud page. Verified August 2026.
Best fit: A platform team whose Prometheus server keeps running out of memory as containers cycle, with dashboards and collectors worth preserving. This is the option a small team can execute over a weekend rather than a quarter.
Look for VictoriaMetrics alternatives if: Your alerting depends on Prometheus's exact rate() behavior, or procurement requires third-party review evidence before sign-off.
Grafana Cloud (Mimir)
Grafana Cloud is a managed observability platform from Grafana Labs. Grafana Mimir stores its metrics, Loki its logs, Tempo its traces, and Pyroscope its code profiles. Mimir runs full PromQL, which makes this the managed option that preserves the most of an existing Prometheus setup.
Grafana Cloud Key Features
- Mimir Query Engine: Runs full PromQL and is the default in Mimir 3.0, so recording rules, alerts, and dashboards move without edits.
- Scale headroom: Grafana Labs reports load-testing Mimir at one billion active time series, well past the point where a single Prometheus server has to be split by hand.
- One account for four signals: Metrics, logs, traces, and code profiles each get a managed backend under a single login.
- Multi-format ingestion: Accepts Prometheus, OpenTelemetry, Graphite, Datadog, and InfluxDB data into one store.
Grafana Cloud Pros and Cons
Pros:
- Grafana Labs treats any deviation from the Prometheus API as a bug rather than a limitation, so compatibility holds as releases ship.
- Per-tenant storage keeps teams sharing one Mimir backend from seeing each other's data.
- The same components exist as open source, so self-hosting Mimir later does not change the query language.
- The free tier covers 10,000 active series and 50 GB per signal, which is enough for a real pilot, not just a demo.
Cons:
- Billing counts active time series, so one misconfigured collection job can multiply the bill overnight before anyone notices.
- Self-managed Mimir holds state in its ingesters and Alertmanagers, which have to be scaled down carefully to avoid downtime or partial query results.
- Grafana Labs has shipped three collection agents in two years: Prometheus Agent, Grafana Agent, and Alloy, and each change forced users to migrate.
- High-resolution metrics bill at $16 per 1,000 series against $6.50 for standard resolution, which catches teams who modeled on the headline rate.
What Users Say About Grafana Cloud
Review-platform reviewers and practitioner forums are effectively discussing two different products: one writes about dashboards, the other about the invoice.
- Dashboards that pull from several data sources at once are the most-praised capability among G2 and Gartner Peer Insights reviewers.
- Teams running Alloy with Mimir report a year or more without significant problems.
- Billing dominates practitioner threads, with a new Kubernetes cluster on Amazon Elastic Kubernetes Service crossing usage thresholds immediately and weekend misconfigurations producing unplanned charges.
- Support gets credit for waiving accidental metric spikes caught quickly, though reviewers note the waiver is discretionary rather than policy.
User sentiment sourced from G2, Gartner Peer Insights, Reddit, and Hacker News as of March 2026.
Grafana Cloud Pricing
- Free: 10,000 active time series, 50 GB each of logs, traces, and profiles per month, 14-day retention.
- Pro: $19 per month platform fee plus usage, with metrics at $6.50 per 1,000 active series and 13 months of metrics retention.
- Enterprise: from a $25,000 per year spend commitment, with metrics as low as $3.00 per 1,000 series.
- Fees and billing: high-resolution metrics cost $16 per 1,000 series, and logs, traces, and profiles are billed separately for processing and writes per gigabyte.
Pricing from Grafana's pricing page. Verified August 2026.
Best fit: Teams already fluent in open-source Grafana that want someone else running the storage while adding logs and traces under one vendor. Set series limits on day one, not after the first surprise invoice.
Look for Grafana Cloud alternatives if: Your series count grows faster than you can govern it, or you want one database for every signal rather than four separate backends.
Thanos
Thanos is an open-source component set, incubating at the Cloud Native Computing Foundation, that adds redundancy and long-term storage to Prometheus servers you already run. It builds around a fleet instead of replacing it: a companion process next to each Prometheus server copies its stored data blocks to object storage, and your collection configuration never changes.
Thanos Key Features
- Sidecar architecture: A companion process adds long-term storage to a running Prometheus instance without touching how it collects or writes data.
- Object-storage retention: Copies data blocks to Amazon S3, Google Cloud Storage, or Azure, so how much history you keep is a budget question rather than a disk-size question.
- Compactor downsampling: Stores 5-minute summaries after 40 hours and 1-hour summaries after 10 days, which keeps multi-year queries fast enough to be usable.
- Stateless queriers: Query nodes scale out horizontally and remove duplicate data when two Prometheus servers are collecting the same metrics for redundancy.
Thanos Pros and Cons
Pros:
- Nothing about your existing setup changes: the same servers, collectors, and configuration files keep running, which is why it is the lowest-risk option here.
- Removing duplicates across a redundant Prometheus pair closes the gap in the data that appears when one of the two goes offline.
- Every component is open source, with no capability held back for a paid tier.
- No single company controls the project, which matters to teams that weigh governance in the decision.
Cons:
- Querier, Store Gateway, Sidecar, and Compactor are four separate processes to deploy, configure, and monitor.
- The sidecar requires turning off Prometheus's own data compaction, which can slow Prometheus down and raise its memory use.
- Queries covering long time ranges spread across multiple Store Gateway instances, so historical queries get slower as retention grows.
- There is no vendor and no rate card, so all operational risk and all support sit with your team.
What Users Say About Thanos
Operators describe a straight trade between the number of components they run and what retention costs them, and they land on both sides of it.
- An operator running roughly 30 clusters chose Thanos three to four years ago and says the team would choose it again.
- Teams that later moved to VictoriaMetrics cite the operational weight, describing the replacement as roughly ten times cheaper to run.
- The Aiven engineering team chose Thanos over Mimir on governance grounds, judging Mimir to be controlled by one company and restrictively licensed.
- The number of moving parts is the consistent complaint, including from teams that stayed.
User sentiment sourced from Reddit and Hacker News as of March 2025.
Thanos Pricing
- Open source: free under Apache 2.0, with no commercial rate card.
- Real cost: object storage, plus the compute running four Thanos components alongside the Prometheus fleet you keep.
- Storage estimate: the project's design documentation puts object storage at about $0.02 per gigabyte.
- Fees and billing: the same documentation adds roughly 20% for data retrieval and query nodes, so storage alone understates the total.
Pricing from the Thanos design docs. Verified August 2026.
Best fit: Organizations running five or more Prometheus servers that need years of history and one place to query it all, but cannot start a migration project this quarter. It buys time without spending your dashboards.
Look for Thanos alternatives if: You want data collected centrally, built-in separation between teams, or fewer processes to run than four.
SigNoz
SigNoz is an open-source observability platform that holds metrics, logs, and traces in one tool, instrumented through OpenTelemetry, the vendor-neutral standard for collecting telemetry from applications. It positions itself as the open-source Datadog alternative and can replace several separate tools in one move.
SigNoz Key Features
- OpenTelemetry-native instrumentation: Built on OpenTelemetry from the start with no proprietary agent, so the instrumentation in your code stays portable if you change vendors later.
- ClickHouse backend: ClickHouse is a columnar database, which gives high compression and lets queries run across many cores at once.
- Correlated signals: Application performance monitoring, tracing, logs, and infrastructure dashboards share one interface, with links between them.
- Alerting coverage: Routes alerts to Slack, PagerDuty, OpsGenie, and Microsoft Teams, with anomaly detection and alerts defined as code, so you don't need a separate Alertmanager deployment.
SigNoz Pros and Cons
Pros:
- Linked views cut the tool-switching that slows down incident triage.
- One OpenTelemetry Collector can send the same data to two backends, enabling a phased migration.
- Self-hosting keeps telemetry inside your own infrastructure, which Datadog cannot offer at any price.
- The Community edition has no seat or host limits, so piloting it across the whole fleet costs nothing.
Cons:
- PromQL works only inside dashboards. The main interfaces are a visual query builder and ClickHouse SQL, so you have to rebuild Prometheus alert rules.
- The comparisons showing large savings against Datadog come from SigNoz's own marketing, not independent analysis.
- The integration catalog is smaller than Datadog's or New Relic's.
- No qualifying peer-review score exists, so procurement has no third-party evidence to weigh.
What Users Say About SigNoz
There is no qualifying third-party sentiment to report, and that is worth stating plainly rather than filling the space with vendor material.
- No G2 product rating is available.
- No Capterra product rating is available.
- Buyers have no peer-review score to use for procurement comparisons.
- Evaluation therefore rests on a hands-on pilot and the vendor's own documentation.
No qualifying third-party user sentiment is available for SigNoz as of August 2026.
SigNoz Pricing
- Community: free, self-hosted, Apache 2.0, with no seat or host limits.
- Teams Cloud: $49 per month base, including $49 of usage, then $0.30 per gigabyte for logs and traces and $0.10 per million metric samples.
- Enterprise: custom, from $4,000 per month, with cloud, bring-your-own-cloud, or self-hosted deployment.
- Fees and billing: retention runs 15 days to one year for logs and traces and 1 to 13 months for metrics; a startup program offers $19 per month for the first 12 months to companies under three years old, under 30 employees, and under $6M raised.
Pricing from SigNoz's pricing page. Verified August 2026.
Best fit: Engineering teams standardizing on OpenTelemetry that want traces and logs in the same place as metrics, and can decide on a pilot rather than peer-reviewed data.
Look for SigNoz alternatives if: You need your Prometheus alert rules to keep working, or a vendor with a large third-party integration catalog.
InfluxDB 3
InfluxDB 3 is a time-series database rewritten in Rust that queries data with SQL and InfluxQL. It accepts Prometheus data through remote_write, the built-in way Prometheus forwards a copy of everything it collects, but it does not run PromQL. It suits teams that prefer SQL over Prometheus tooling.
InfluxDB 3 Key Features
- SQL through Apache DataFusion: Standard SQL over time series, including joins across datasets that PromQL cannot express.
- No cardinality ceiling: The version 3 engine removes the limit on distinct label combinations that constrained earlier versions and caused Prometheus to crash.
- Parquet on object storage: Data is written as Apache Parquet files, an open format other query engines can read, on low-cost object storage with no forced retention policy.
- Single machine to managed service: The same engine runs on one machine at the edge or as a managed service, so an edge collector and a production cluster use the same tooling.
InfluxDB 3 Pros and Cons
Pros:
- Containers starting and stopping no longer create a capacity risk, because the engine has no cardinality limit to exhaust.
- Parquet is an open file format, so stored telemetry stays readable by other tools rather than locked behind one vendor's API.
- Existing Prometheus servers forward data after a one-line configuration change, so ingestion can move before any queries do.
- SQL puts telemetry within reach of anyone on the team who already queries the data warehouse.
Cons:
- PromQL isn't supported, so every existing dashboard and alert rule must be rewritten.
- A single-machine deployment has no built-in redundancy or replication.
- Flux, the query language in version 2, is gone from version 3, so InfluxDB 2.x users face a rewrite whichever platform they choose.
- Three query languages across three major versions is a poor record for a system you plan to keep for years.
What Users Say About InfluxDB 3
Sentiment focuses less on the current product than on the sequence of changes that produced it.
- The move from InfluxQL to Flux to SQL is the loudest criticism and has cost the product trust.
- Teams that built pipelines on Flux describe its removal as a forced rewrite.
- New practitioners treat SQL support as a reason to choose it, not a disruption.
- Kubernetes practitioners still shortlist it as a simple option for basic monitoring and alerting.
User sentiment sourced from Reddit and Hacker News as of September 2023.
InfluxDB 3 Pricing
- InfluxDB 3 Core: free, open source, single machine.
- Cloud Serverless: usage-based at $0.0025 per megabyte written, $0.012 per 100 queries run, $0.002 per gigabyte-hour of storage, and $0.09 per gigabyte of data out.
- Enterprise and Cloud Dedicated: contact sales; Enterprise includes a 30-day trial.
- Fees and billing: new paid accounts get a $250 credit for the first 30 days, the meter has four parts, so query volume moves the bill as much as ingest volume does.
Pricing from InfluxData's pricing page. Verified August 2026.
Best fit: Data-heavy teams in connected devices, industrial systems, or product analytics that want to query telemetry with the same SQL tooling as the rest of their data. Choose it for the joins, not the price.
Look for InfluxDB 3 alternatives if: Your monitoring investment lives in PromQL dashboards and alerts, or losing Flux left you wanting query-language stability above all.
Datadog
Datadog is a fully managed platform covering observability and security monitoring. Its agent reads Prometheus endpoints, but you query everything in Datadog's own language, so migrating means rebuilding your Prometheus queries in Datadog.
Datadog Key Features
- More than 1,000 integrations: Cloud services, databases, and log sources connect with dashboards already built, which removes most of the collector wiring.
- Signals in one place: Metrics, logs, traces, and application performance monitoring share a platform, so an alert links straight to the trace and log lines behind it.
- Bits AI suite: AI-assisted investigation correlates telemetry automatically and proposes root causes, with chat, code, and workflow agents extending it.
- Prometheus and OpenTelemetry ingestion: The agent reads Prometheus endpoints and the platform accepts OpenTelemetry data, so existing collectors keep feeding it while dashboards get rebuilt.
Datadog Pros and Cons
Pros:
- No monitoring infrastructure to run, patch, or capacity-plan.
- Accepting both Prometheus and OpenTelemetry data means both can feed the platform during a phased rebuild.
- Cloud integrations produce usable dashboards within minutes of connecting an account.
- Integration coverage is the widest here, which is why consolidation projects tend to land on it.
Cons:
- It is only available as a hosted service, with no self-hosted option for teams with data-residency requirements.
- Reading Prometheus endpoints is capped at 2,000 metrics per instance.
- PromQL is not supported, so dashboards and alerts get rebuilt in Datadog's language, which raises the cost of leaving as well as arriving.
- Separate meters for infrastructure, tracing, logs, and security make the total genuinely hard to forecast.
What Users Say About Datadog
Integration coverage is why reviewers consolidate onto it, and the invoice is what they write about afterwards.
- Real-time dashboards and integration coverage earn the most praise, with practitioners conceding that most alternatives cover a fraction of the same ground.
- Unpredictable cost is the dominant complaint everywhere, driven by host counts and by custom metrics with many label combinations.
- Reviewers report integration changes that multiplied their charges without warning.
- Support draws criticism for handling non-production issues by email with response times over a day.
User sentiment sourced from G2, Capterra, Gartner Peer Insights, Reddit, and Hacker News as of August 2024.
Datadog Pricing
- Infrastructure Pro: $15 per host per month billed annually.
- Application performance monitoring: $31 per host per month billed annually, or $36 month-to-month, with APM Pro at $35 and APM Enterprise at $40.
- Log Management: $0.10 per gigabyte ingested, with standard 15-day indexing at $1.70 per million log events per month billed annually.
- Fees and billing: Cloud SIEM is $5 per gigabyte analyzed with 12-month retention, Bits AI runs $500 for 500 credits per month annually or $1.30 per credit month to month, and a 14-day trial covers the platform.
Pricing from Datadog's rate list. Verified August 2026.
Best fit: Organizations consolidating monitoring, logging, tracing, and security under one vendor, with someone already accountable for controlling usage per module. Without that, this is the entry with the widest gap between quote and invoice.
Look for Datadog alternatives if: Predictable cost matters more than convenience, or compliance requires telemetry to stay in your own infrastructure.
New Relic
New Relic is a managed observability platform that puts all telemetry in one database, including Prometheus data forwarded through remote_write. Queries run in NRQL, its SQL-like language, through a translation layer the company says covers more than 99.5% of PromQL-style queries. That figure is the vendor's own and is not independently verified.
New Relic Key Features
- Prometheus remote_write intake: Existing servers forward their data after a configuration change, with no re-instrumentation of application code.
- NRQL: SQL-like querying across every signal, readable by anyone who already writes SELECT statements.
- AI incident tooling: Outlier Detection and Intelligent Root Cause Analysis correlate anomalies across services, infrastructure, logs, and traces.
- More than 780 integrations: Coverage across AWS, Azure, Google Cloud, and application stacks feeds one database.
New Relic Pros and Cons
Pros:
- Prometheus can keep collecting throughout a phased move to managed storage.
- NRQL lowers the barrier for engineers who know SQL but not PromQL.
- One query can span metrics, logs, and traces without manually joining separate stores.
- A single database for every signal avoids the four separate backends Grafana Cloud keeps.
Cons:
- PromQL is translated rather than run natively, and the accuracy of that translation rests on a vendor claim.
- Reviewers report alert noise: false positives, duplicate incidents, and correlation that fails to group related events.
- Practitioners rate it weaker for pure infrastructure monitoring than for application performance monitoring.
- Per-user charges on full-platform seats compound alongside the per-gigabyte data charges.
What Users Say About New Relic
Data charges and alert quality dominate the record in roughly equal measure.
- NRQL earns consistent praise as a query language people can pick up quickly.
- Tracing gets credit for locating the source of latency across services.
- Billing spikes from log ingestion and per-query dashboard charges draw the sharpest complaints, with some users reporting storage charges that more than quadrupled.
- Threads through 2026 question the platform's direction, with teams documenting moves to open-source Grafana stacks.
User sentiment sourced from Capterra, Gartner Peer Insights, and Reddit as of January 2026.
New Relic Pricing
- Free: 100 GB per month of data, one full-platform user, unlimited basic users, eight-day minimum retention.
- Data: $0.40 per gigabyte beyond the free allowance, or $0.60 per gigabyte with Data Plus.
- Users: Core users at $49 per user per month; Standard full-platform users at $10 for the first and $99 for each additional user, to a maximum of five.
- Fees and billing: Pro runs $349 per user per year on an annual commitment against $418.80 per user per month month-to-month, EU data storage adds $0.05 per gigabyte monthly, and Enterprise goes through sales.
Pricing from New Relic's pricing page. Verified August 2026.
Best fit: Teams with a large number of hosts but disciplined data volume, where forwarding Prometheus metrics into managed storage beats running it yourself and engineers already work in SQL.
Look for New Relic alternatives if: Log volumes are heavy, seat counts multiply quickly, or you need PromQL run natively rather than translated.
Dynatrace
Dynatrace is an enterprise observability platform whose distinguishing capability is Davis AI, an engine that identifies the cause of an incident rather than listing its symptoms. It accepts Prometheus metrics through several documented routes, including Kubernetes collection and the OpenTelemetry Collector.
Dynatrace Key Features
- Davis AI root-cause analysis: Names what broke instead of paging on every symptom, collapsing a storm of alerts into one finding.
- OneAgent auto-instrumentation: Finds and instruments supported application stacks without anyone writing collector configuration.
- Backend and user data together: Server telemetry and real-user experience data correlate in one platform, so incident reviews need no exports between tools.
- Prometheus and OpenTelemetry ingestion: Existing collectors keep running while OneAgent covers the application layer, so neither has to be retired first.
Dynatrace Pros and Cons
Pros:
- Dependency and topology mapping happens automatically, giving responders a live map of service relationships nobody had to draw.
- Automatic discovery covers large estates that would take months to instrument by hand.
- Real-user data sits beside backend traces, so a slow page traces back to the service causing it.
- Charges are based on consumption rather than seats, so the bill does not grow as more people get access.
Cons:
- Practitioners report OneAgent adding latency on high-traffic services, and containers failing with obscure loader errors that are hard to diagnose.
- Instrumenting hundreds of applications with a proprietary agent makes removing it later a significant engineering project.
- Davis AI can over-alert once its customization options run out, producing the noise it exists to remove.
- Consumption-based metering is hard to forecast, which is the most cited procurement friction.
What Users Say About Dynatrace
Reviews split on forecasting even among teams that credit Davis AI with cutting triage time.
- Reviewers credit Davis AI with explaining failures rather than flagging them, giving one answer instead of a hundred alerts.
- Consumption-based licensing draws steady forecasting complaints.
- Some reviewers report that asking for usage guidance turned into a contract-expansion conversation.
- Gartner Peer Insights reviewers describe the documentation as short on implementation examples, and report tickets passing between first-line technicians without escalation.
User sentiment sourced from Gartner Peer Insights, Reddit, and Hacker News as of May 2026.
Dynatrace Pricing
- Full-Stack Monitoring: $0.01 per gigabyte of application memory per hour.
- Infrastructure Monitoring: $0.04 per host per hour, which works out to roughly $29 per host per month if a host runs continuously.
- Metering model: both published rates are based on consumption rather than seats, so the number of people using it does not change the bill.
- Fees and billing: because the meter runs hourly, the annual total depends on how much of the time your hosts and applications are actually running.

Best fit: Large enterprises with mixed and partly legacy estates where automatic discovery and AI triage matter more than keeping an exit path open. The agent is the value and the lock-in at the same time.
Look for Dynatrace alternatives if: You run latency-sensitive high-throughput services, or your strategy is OpenTelemetry-first with portability protected.
Zabbix
Zabbix is an open-source infrastructure and network monitoring platform that includes collection, dashboards, alerting, templates, and escalation in one product. It collects data through its own agents and via SNMP, the standard protocol switches and routers use to report their health. Many organizations run it beside Prometheus rather than instead of it.
Zabbix Key Features
- SNMP and agent collection: Network devices and bare-metal servers work out of the box, which takes real effort to replicate with Prometheus collectors.
- Everything in one product: Alerting, escalation chains, and dashboards are built in, with no separate Alertmanager or Grafana to run.
- Device templates: Mature templates cover environments monitoring tens of thousands of devices.
- Database-backed scaling: Runs on PostgreSQL or MySQL, with TimescaleDB the community recommendation for large deployments.
Zabbix Pros and Cons
Pros:
- Templates carry the configuration for a device model, so adding a new switch or server type does not mean writing and shipping code.
- Alerting, escalation, and dashboards live in the same product as collection.
- Agent and SNMP collection reaches switches, routers, and bare-metal hosts that have no Prometheus collector available at all.
- Every capability is included in the free build, with nothing held back for a paid tier.
Cons:
- Setup and tuning are heavily manual, and reviewers describe standing it up properly as a project measured in months.
- The interface is dated, and the database design limits the kinds of analytical queries you can run.
- Support for containers and cloud services is thin, and practitioners describe fast-changing environments as a poor fit against Prometheus.
- The agent's security model grants broad remote access, which becomes a review item in regulated environments.
What Users Say About Zabbix
Sentiment is unusually consistent across review platforms and forums, which is rare for a product this old.
- Systems administrators call it the tool that can monitor almost anything, once learned.
- Practitioners find it easier to stand up for traditional infrastructure than a combined Prometheus, Thanos, and Grafana stack.
- Published designs cover 1,000 or more network devices, and nearly 5,000 servers on a tuned database, and larger organizations pair it with Prometheus for container workloads.
- Criticism clusters on the learning curve, with one practitioner reporting almost a year to configure it properly, plus the agent security model and databases hanging under heavy load.

Zabbix Pricing
- Open source: free to run, with every capability included.
- Real cost: your database, your compute, and administrator time, which is the dominant line for this entry.
- Commercial support: available directly from Zabbix, quoted per engagement rather than published.
- Fees and billing: no rate card exists for the free build, so budgeting means sizing infrastructure and administrator hours instead.

Best fit: Mixed estates with a lot of network gear and bare-metal servers, where out-of-the-box SNMP coverage outweighs the gaps around containers. Budget the setup phase in months, not weeks.
Look for Zabbix alternatives if: Your workloads are containerized and short-lived, or your team cannot absorb a long manual setup and tuning phase.
Where Siit Fits
Siit handles the request traffic around a monitoring stack, not the stack itself. It does not collect metrics, store time series, or run PromQL, and it lists no native integration with any monitoring platform on this page. What it does own is the work those platforms generate for whoever answers requests: a Grafana seat for a new engineer, an admin permission change on the observability tool, access restored mid-incident during an on-call handoff. Those arrive in Slack or Microsoft Teams and become tracked work in a request layer instead of a direct message someone forgets.
From there, Okta actions cover password resets, group changes, and app assignments; approval routing is logged end to end, and escalations hand off cleanly: Siit's Jira sync works in both directions where Jira Service Management stays the system of record, and GitLab issues behave the same way for engineering handoffs, across 500+ connectable apps.
The payoff shows up in headcount, not dashboards. Unit's lean IT story is the shape of it: a two-person team supporting more than 200 employees across three countries, with a 60% cut in helpdesk labor and an audit trail that maintains itself. Engineering service desks covers the pattern in more depth.

FAQs
Can you reuse existing Prometheus collectors?
Yes, on the compatible backends. VictoriaMetrics accepts data forwarded through remote_write as well as metrics pulled from your existing collectors, and Mimir uses the same remote_write configuration. Ingestion can therefore move first while dashboards and alert rules stay where they are, which turns a migration into a series of reversible steps rather than one cutover weekend.
How do you migrate historical Prometheus data?
VictoriaMetrics' vmctl tool imports Prometheus snapshots and can also pull history through the remote read protocol. Grafana's Mimir backfill tool uploads existing Prometheus data blocks. One path does not work: Thanos blocks cannot be uploaded to Mimir directly, because their metadata contains labels Mimir rejects. Plan that conversion separately if you are leaving Thanos.
Self-hosted or managed: what actually changes?
VictoriaMetrics writes to attached disks while Grafana Mimir writes to object storage, which changes how you plan capacity. Self-hosting leaves installation, capacity planning, and maintenance with your team. Grafana Cloud runs the central storage, but your team still owns instrumentation, collectors, network connectivity, and access policies, so the handoff is partial, not total.
Do Prometheus alert rules survive a migration?
On the PromQL-compatible backends, mostly. Mimir's Ruler evaluates PromQL rules against your data and sends alerts to Mimir Alertmanager, and VictoriaMetrics uses vmalert for the same job. Both keep the rule format. Test any alert built on rate() or increase() directly, because VictoriaMetrics calculates it from actual timestamps, while Prometheus estimates between them.
Does Prometheus 3 remove the need to switch?
Partly. Prometheus 3 adds native histograms, Remote Write 2.0, UTF-8 support, and an OpenTelemetry receiver, and the 3.x line has a long-term-support schedule. The official documentation describes that OpenTelemetry receiver as suited to specific low-volume cases rather than general use. Storage is still single-machine, so redundancy, replication, and summarizing old data still need another system.
