The best Sentry alternatives, compared honestly
Sentry is the category-defining error & performance monitor — but as it grows into a full observability suite with a multi-axis quota model, teams leave over cost and billing complexity, not quality. Here are the alternatives that actually hold up, by need.
The best Sentry alternative depends on what's pushing you off it:
- Keep your Sentry SDKs, drop the bill → GlitchTip — open-source, Sentry-SDK-compatible, free to self-host.
- Most generous free tier / all-in-one → PostHog — 100k errors/mo free, bundled with analytics & replay.
- Small / indie team, predictable pricing → Honeybadger — errors + uptime + cron, clear billing.
- Full observability, self-hosted → SigNoz — OpenTelemetry-native errors, traces & metrics.
Why teams look elsewhere
What pushes teams off Sentry
Sentry's tooling is excellent — the friction is almost entirely about cost, quota complexity and scope creep.
Multi-axis quotas
Errors, tracing spans, replays, logs, attachments and cron/uptime monitors are each metered separately, which makes the monthly bill hard to predict.
The Aug 2025 repricing
On Aug 27, 2025 Sentry cut base spans to 5M and raised reserved-spans pricing by $8/mo (Team) and $16/mo (Business), and made Logs a billable product.
$40/contributor AI add-on
Seer, Sentry's AI debugger, is billed at $40 per active code contributor per month — an extra line item that scales with team size.
Scope creep
Sentry keeps expanding from error tracking into a broader observability platform. Teams who only want errors end up paying for a suite they don't use.
Heavy self-host
Self-hosted Sentry is free but runs 40+ containers — a real ops project. Teams wanting data in-house often want something lighter.
Overage surprises
Pay-as-you-go events on top of base quota, plus $0.50/GB for extra logs, mean a traffic spike or a noisy release can spike the invoice.
The shortlist
8 Sentry alternatives worth trying
Ranked by how well they solve the most common reason to switch. There's no single winner — the best pick depends on your volume, budget and whether you want to self-host.
Open-source (MIT), Sentry-SDK-compatible — point your existing DSN at it. Free to self-host (a handful of containers), hosted free tier at 1k events/mo, paid from $5/mo. Trade-off: thinner tracing/replay and no Seer-grade AI. Sentry vs GlitchTip →
100k errors/mo free, with error tracking bundled into product analytics, session replay and feature flags. Best if you want one platform. Trade-off: error tracking is newer and less deep than Sentry's.
Simple, predictable pricing (free tier; Team $26/mo; Business $80/mo) bundling errors + uptime + cron monitoring, known for clear billing and support. Trade-off: smaller ecosystem, lighter tracing.
Now SmartBear Insight Hub. Strong stability scores and release health for mobile/app teams; free 7,500 events/mo, paid from ~$22/mo. Trade-off: web/backend story is weaker than its mobile roots.
One of the original real-time trackers, strong at automated grouping and triage workflows; free 5k occurrences/mo, paid from ~$9–16/mo. Trade-off: UI and tracing feel dated next to Sentry. Sentry vs Rollbar →
OpenTelemetry-native — errors, traces, metrics and logs in one Apache-2.0 platform. Self-host free; cloud from ~$49/mo; beats Sentry ~5–6× at very high volume. Trade-off: heavier to run, more DIY.
Flat-rate pricing that wins at high event volume, bundling error tracking + logs + uptime + incident management. Trade-off: errors are part of a monitoring suite, not the deepest standalone tracker.
Sentry-SDK-compatible and designed to run in a single container — data on your own box with near-zero ops. Trade-off: young project, error tracking only (no tracing or replay).

Tie it into your pipeline
Where Buddy fits (it's not on this list)
Buddy isn't a Sentry alternative — it works with them
Buddy is a CI/CD and deployment platform, not an error tracker, so it doesn't belong in the ranking above. It's here because whichever tracker you pick, you'll want it wired into your pipeline so releases and deploys are tagged automatically — and Buddy does exactly that.
Buddy ships native Sentry and Sentry Self-Hosted pipeline actions that create a release and notify your tracker on every deploy — so each error ties back to the exact build that shipped it. It works the same way with most trackers on this list via their release APIs.
A fair call
When Sentry is still the right choice
Switching isn't always worth it. Sentry earned its reputation for a reason.
Sentry is fine if…
- You want the deepest error + performance tooling and best-in-class SDK coverage across ~100+ stacks.
- You're already invested in its releases, tracing spans, session replay and Seer AI, and the bill is acceptable.
- Your volume sits inside the base quotas and you value one mature, hosted vendor.
- You want error tracking, tracing and replay from a single tool without stitching pieces together.
Consider an alternative if…
- The multi-axis quota bill is unpredictable — GlitchTip (self-host) or Better Stack (flat-rate) are cheaper.
- You want to keep your Sentry SDKs but drop the cost — GlitchTip or Bugsink are drop-ins.
- You'd rather one platform for errors + analytics + replay — PostHog.
- You need data fully in-house with minimal ops — Bugsink (single container) or SigNoz.
Common questions
Sentry alternatives — common questions
What is the best free Sentry alternative?
For a free hosted tool, PostHog has the most generous free tier at 100,000 errors per month. For free forever with no event cap, self-host GlitchTip or Bugsink — both are open source and cost only your server (typically $6–12/month on a small VPS). GlitchTip and Bugsink also accept Sentry SDK events, so you can switch by changing the DSN.
Which Sentry alternative is a drop-in replacement?
GlitchTip and Bugsink are the closest drop-in replacements because they're compatible with the Sentry client SDKs. You keep your existing instrumentation and simply point events at a GlitchTip or Bugsink DSN instead of sentry.io, so there's little to no code change.
Is self-hosting Sentry worth it?
Self-hosted Sentry is free and full-featured, but it runs 40+ containers and is a real operational project to keep healthy. If you need data on your own infrastructure with far less overhead, self-hosted GlitchTip (a handful of containers) or Bugsink (a single container) are lighter, and SigNoz is the option if you want full observability, not just errors.
Did Sentry get more expensive in 2025?
On August 27, 2025 Sentry cut the base tracing-spans quota to 5M and raised reserved-spans pricing by $8/month on Team and $16/month on Business plans, while introducing Logs as a separate billable product. Base error prices held (Team ~$26/mo annually, Business ~$80/mo annually), but tracing-heavy teams saw higher effective bills. The AI debugger, Seer, is a $40 per active contributor per month add-on.
What happened to Highlight.io?
Highlight.io was acquired by LaunchDarkly on April 23, 2025. Its standalone service is deprecating on February 28, 2026 and folding into LaunchDarkly Observability, and open-source development has slowed. It's no longer a safe place to start a new project — existing users must migrate to LaunchDarkly's SaaS.
Can I migrate my existing Sentry error data?
Generally no — historical events don't transfer between platforms. The practical migration is to switch the SDK or DSN going forward and start collecting fresh. To GlitchTip or Bugsink you only change the DSN; to PostHog, Honeybadger, Rollbar or Bugsnag you swap the SDK and re-map alert rules. Run the old and new tool in parallel briefly, then cut over.
Sentry vs Datadog or New Relic — which is better for error tracking?
If you only need error tracking, Sentry (or a lighter alternative like GlitchTip or Honeybadger) is more focused and cheaper. Datadog and New Relic treat error tracking as one feature of a full APM/observability suite — powerful if you also want infrastructure metrics, logs and traces in one place, but usually overkill and more expensive for pure error monitoring. Sentry vs Datadog →
