Teams look for a Sentry alternative when event-based quotas start to drive the bill, when they want full infrastructure monitoring next to error tracking, or when they want to run the whole stack on their own servers with real support. They move to flat or request-based tools, to broader observability platforms, or to self-hosted open source.
Short answer: The closest replacements for Sentry in our application performance monitoring ranking are AppSignal, Raygun and SigNoz. Choose AppSignal if you run a Ruby, Elixir, Node.js or Python app and want a predictable bill with unlimited users. All 11 alternatives below are ranked products from Best Application Performance Monitoring Software in 2026, and each says where it differs from Sentry.

Why buyers look past Sentry
01
Quotas count events, and spikes use them up
Sentry prices by quota of errors, spans and session replays. The Developer plan is free for one user and includes 5k errors, 5M spans and 50 session replays. The Team plan starts at $26 a month billed annually with 50k errors. A noisy release or a retry loop can consume a month of errors in an afternoon, so teams with unpredictable volume look at tools with fixed tiers or published per-GB rates.
02
Application focus, not the whole estate
Sentry documents errors, tracing, session replay, profiling, logs, metrics, uptime and cron monitoring. It is built around the application and the developer. Teams that also need infrastructure, Kubernetes and network views, or one query layer across several data types for operations staff, often end up on a platform that covers hosts as well.
03
Self-hosting is possible but not supported
Sentry can be self-hosted, which attracts teams with data-residency rules. The documentation is direct about the terms: the licence is the Functional Source License (not OSI open source, converting to Apache 2.0 after two years), it needs at least 4 CPU cores and 16 GB RAM plus 16 GB swap, and it comes with no guarantees or dedicated support. Some features, including the Seer AI features, are not available self-hosted.

What each one does differently
1
AppSignal
Netherlands · Free plan with 30K requests a month; paid plans by request volume, published
AppSignal is the closest in spirit: error tracking and performance monitoring for application teams, but with plans by request volume and no overage charges (the vendor says it only enforces limits after two of three months over). The free plan covers 30K requests with 5-day retention. It is narrower in scope than Sentry on session replay and profiling.
Switch from Sentry if you run a Ruby, Elixir, Node.js or Python app and want a predictable bill with unlimited users.
New Zealand · Per product by monthly event or trace volume, published
Raygun sells crash reporting, real user monitoring and APM as three separate products, each with its own plan and reserved event volume, and all start with a 14-day trial rather than a free plan. Overage is charged per error, session or trace. It costs more to combine products than Sentry's single bundle.
Switch from Sentry if you want crash reporting and user-experience monitoring as distinct, separately budgeted products.
India · Open source self-hosted; cloud from USD 49 a month, priced per GB ingested, published
SigNoz is an OpenTelemetry-based observability tool with a free self-hosted Community edition and a cloud Teams plan from $49 a month that includes $49 of usage, then $0.30 per GB for logs and traces. There are no per-user or per-host charges. It is built around traces, logs and metrics rather than Sentry's issue-triage workflow.
Switch from Sentry if you want to self-host an observability stack, or pay per GB ingested instead of per event quota.
United States · Free tier; Pro has a monthly platform fee plus usage on metrics, logs and traces and per active user, published
Grafana Cloud bundles metrics, logs, traces and profiles with a free tier (50 GB of logs and 50 GB of traces a month, 14-day retention, three active users). The Pro plan adds a $19 platform fee plus usage. It leans on the Grafana dashboard ecosystem and is a toolkit to assemble, where Sentry is a ready-made error workflow.
Switch from Sentry if you already use Grafana dashboards and want errors, metrics and logs in one place.
United States · Free tier; per event ingested per month, published
Honeycomb is built for exploring high-cardinality trace data in production, not for grouping and assigning errors. The free tier allows 20M events a month, and Pro starts at $150 a month for up to 750M events, with unlimited seats on every plan. Its debugging workflow is query-driven rather than issue-driven.
Switch from Sentry if your problem is understanding slow or odd behaviour across services, not triaging exceptions.
United States · Free tier of 100 GB a month; then per GB ingested plus per core and full-platform user, published
New Relic bills by data ingested and by user: 100 GB a month and one full platform user are free, then $0.40 per GB, with full platform users priced per seat on paid editions. It covers hosts, containers and logs without host-based charges. The per-seat cost for full users is a different pressure from Sentry's event quotas.
Switch from Sentry if you want application and infrastructure monitoring in one platform and few people need full access.
United States · Free tier to 5 hosts; per host per month plus per GB of logs and per custom metric, published
Datadog charges per host for APM (from $31 a month when added to infrastructure monitoring, billed annually, $36 standalone) and per GB or event for logs, with Error Tracking included alongside APM. It is a full operations platform, a large step up in scope and in billing dimensions from Sentry's quota model.
Switch from Sentry if you already run infrastructure on Datadog and want errors to sit beside hosts and logs.
Germany · Usage-based per million spans, log records and metric data points, published; 14-day trial
Dash0 prices telemetry per million units: spans, logs and web events at $0.06 ingestion plus $0.54 storage, with 30-day retention. It has a 14-day trial and no free plan. It is OpenTelemetry-oriented and aimed at operations teams, and it does not centre on the developer-facing error inbox that Sentry provides.
Switch from Sentry if you instrument with OpenTelemetry and want usage-based pricing with budget limits.
Germany · By monthly request volume in published tiers; 14-day trial
Tideways is a PHP profiler and monitor from Berlin, priced by monthly request volume in tiers from 5M to 1B requests, with no overage pricing and a 14-day trial. It does one language well and does not cover the JavaScript, mobile and session replay breadth that Sentry documents.
Switch from Sentry if your application is PHP and you want profiling with a fixed monthly price.
Netherlands · Consumption-based on ingest and retention, published rates
Elastic Observability serverless bills on data ingested and retained, with logs from about $0.07 per GB ingested and $0.017 per GB-month retained on Logs Essentials, and more on the Complete tier. It is built on search and log analytics rather than error grouping, and needs more setup than Sentry's SDK-first onboarding.
Switch from Sentry if you already store logs in Elastic and want traces and alerts on the same data.
Austria · Consumption-based per host hour or memory-GiB hour and per GiB ingested, published rates
Dynatrace is an enterprise platform billed through an annual commitment with a published rate card, for example $58 a month per 8 GiB host for Full-Stack Monitoring. It offers a 15-day trial and automatic discovery of hosts and services. It suits large estates, and is far heavier than a developer-first error tool.
Switch from Sentry if an operations organisation needs one commercial platform across many hosts and containers.
Sentry stays the right choice when developers are the main users and the question is which exception broke in which release. Issue grouping, release tracking, session replay and tracing sit in one product, there are unlimited users on paid plans, and the free Developer plan lets one person start without a card. If event volume is steady and fits a plan's quota, the quota model is predictable rather than a problem.
05
What moving off Sentry involves
01
SDKs and releases are re-instrumented
Error tracking depends on an SDK in each application and on release and source-map uploads in your build. Plan to swap the SDK per service, re-upload source maps or debug symbols, and re-create alert rules. Run the new tool in parallel for a release cycle before removing Sentry.
02
Issue history does not travel
Resolved issues, assignments and regression history are stored in Sentry. Export what you need for audit or recurring-bug research before the plan ends, and check the retention you have today (30 days on the Developer plan, up to 90 on Team and Business) against what the new tool keeps.

Questions about replacing Sentry
5 answers
Is there a free alternative to Sentry?
SigNoz offers a free self-hosted Community edition, and Sentry itself can be self-hosted under its Functional Source License.
Grafana Cloud, Honeycomb, AppSignal and New Relic each have a free tier with limits on data, events or requests. Free self-hosting trades licence cost for the work of running it.
Can I self-host Sentry?
Yes. The documentation lists at least 4 CPU cores, 16 GB RAM plus 16 GB swap and 20 GB disk, and states that self-hosted Sentry has no guarantees or dedicated support. Some features, such as Seer, are not included.
Is Sentry open source?
Not by the OSI definition. It uses the Functional Source License, which the vendor calls Fair Source, and the code becomes Apache 2.0 after two years. You cannot resell it or use it competitively against Sentry.
Which Sentry alternative has the most predictable pricing?
AppSignal prices by request volume with no overage charges, and Tideways charges exactly the agreed tier with no overage pricing. Both are narrower than Sentry. Usage-based tools such as SigNoz, Dash0 and Elastic publish per-unit rates, so the bill follows volume.
Do I need a full observability platform instead of Sentry?
Only if you also need infrastructure, Kubernetes and log analytics in the same place. Datadog, New Relic, Dynatrace and Grafana Cloud cover that wider scope. If your pain is application errors, a platform adds cost and setup without solving it.
