The best Sentry alternatives are GlitchTip for cheap open source error tracking, Honeybadger, Rollbar, and Bugsnag for like for like error tracking, Highlight for errors plus session replay, and Fixter if you want a tool that investigates what broke and tells you what to act on instead of handing you another list. The honest reason most teams start looking is not the price. It is that Sentry shows you that something is wrong but does not tell you which errors matter or what to do about them, and a small team does not have the time to sit and triage a feed of exceptions by hand.
Why teams look for a Sentry alternative
Sentry is very good at one job: catching application errors, grouping them, and giving you the stack trace. The catch is what happens after that. Sentry shows you that something is wrong. It does not tell you which of the hundred grouped issues is the one taking down checkout right now, it does not chase you to act on it, and it does not do the digging to find out why it broke. That part is left to you.
On a big team with someone watching the error feed all day, that is fine. On a team of five shipping features, it is not. The errors pile up in a tab nobody opens. You find out a release was broken when a customer emails you, not when Sentry caught the exception three hours earlier. The tool had the information the whole time. It just had no way to make you act on it. And this is not really a pricing complaint: the free Developer plan covers 5,000 errors a month, and the Team plan is $26 a month for 50,000 errors with unlimited users,1 so for most small teams the money is not the issue. The time to use what they are paying for is.
So teams go looking, and they tend to want one of two things: the same error tracking for less money, or a tool that does something with the errors instead of just listing them. A narrower third group hits the event-volume wall, where Sentry bills by how many error events you send and a noisy release chews through quota in minutes, covered below.
The event-volume problem
Billing by error event sounds fair until a single bad deploy starts throwing on every request. Say one endpoint serving 100 requests a second starts failing. That is 6,000 error events a minute, 360,000 an hour.1
| Window | Error events at 100/sec |
|---|---|
| Per minute | 6,000 |
| Per hour | 360,000 |
| Team plan monthly quota (50,000) | gone in ~8 minutes |
| Free plan monthly quota (5,000) | gone in under a minute |
To be fair to Sentry, this is not a runaway bill. Spike protection watches your normal volume and rate-limits events past a dynamic threshold, and once your quota and any pay-as-you-go budget are used up, further events are simply dropped, not charged.3 So the failure mode is not a surprise invoice. It is worse in a way: you go blind. The events get dropped exactly when something is on fire, which is the one moment you needed them. The real cost of event-volume billing for a small team is paying to keep quota headroom you mostly do not use, so that you still have visibility on the day you do.

Each alternative, in detail
GlitchTip: the open source, drop-in option
GlitchTip is an open source error tracker that is compatible with Sentry's SDKs. Because it speaks the same protocol, you can often repoint your existing DSN at it and keep working, no re-instrumentation. Self host it for the cost of a small server, or use the hosted plan: 1,000 events a month free, then $15 a month for 100,000 events.4 If the reason you are leaving Sentry is cost, and you only need error tracking, GlitchTip is the most direct swap.
Rollbar, Bugsnag, and Honeybadger: like for like
These three are the closest commercial equivalents to Sentry. Rollbar has strong grouping and a good triage workflow, with a free tier around 5,000 occurrences a month. Bugsnag, now part of SmartBear, leans into release health and stability scores, which suits teams shipping mobile or frequent releases. Both price on usage-based sliders, so check their current pages for the exact tier you need. Honeybadger is the most predictable of the three: $26 a month with unlimited users,5 bundling error tracking with uptime and cron monitoring at flat pricing that does not move with a noisy release. Small teams tend to like that the bill is known in advance.
Highlight: errors with session context
Highlight is open source, under Apache 2.0, and pairs error tracking with session replay and logs, so you can see what the user did before the error fired. Its cloud tier is free for 500 sessions a month, then pay as you go from $50 a month.6 That session context is useful for front end bugs that are hard to reproduce. It sits between a pure error tracker and a broader monitoring tool.
SigNoz: errors inside full monitoring
If the real reason you are unhappy with Sentry is that it only sees errors, SigNoz is worth a look. It is an open source platform covering logs, metrics, and traces in one app on an OpenTelemetry backend, free to self host or $49 a month on cloud, so exceptions sit alongside the slow queries and failed jobs that error tracking misses. It is also one of the strongest Datadog alternatives, so it doubles as a way to consolidate tools.
Fixter: investigation instead of a longer error list
Every tool above gives you a better or cheaper list of what went wrong. Fixter is built to tell you why and what to do about it. When an error or a complaint comes in, it pulls the related logs and traces, finds the root cause, and maps the impact, then returns the conclusion. You ask in plain language over MCP, from Claude Code or Cursor. More on the difference below.
Open source and self-hosted Sentry alternatives
For an open source error tracker, GlitchTip is the cleanest option because it is Sentry-SDK compatible and light to run. Highlight is open source too, with session replay and logs around it. SigNoz is open source if you want errors inside a full monitoring stack.
Sentry itself is sometimes called open source, but the nuance matters: its code is source-available under a fair-source license, not a standard open source one, and self hosting the full platform is genuinely heavy. The official self-hosted setup runs Postgres, Redis, Kafka, ClickHouse, and several workers, needs at least 16GB of RAM, and is documented as being for low-volume deployments and proofs of concept, with no scaling support.7 That is exactly the gap GlitchTip fills. As always, self hosting trades a vendor bill for infrastructure and time, which is worth it for a light tracker and rarely worth it for a heavy platform.
Visibility is not the same as action
This is the real reason most teams end up moving, and it is worth being precise about. Sentry gives you visibility. It catches the exception, groups it, and puts it on a list. What it does not give you is action: a reason to deal with this one now, and the answer to what actually broke. A small team does not lack visibility. It lacks the hours to turn a feed of errors into decisions.
Sentry can notify you, to be fair. It has issue alerts and regression alerts. The trouble is that it notifies you about everything the same way. A new-issue alert fires whether it is one user hitting an edge case or checkout being down for everyone, so the alerts become the same undifferentiated noise as the feed, and you mute them. That is exactly the alert fatigue trap: a tool can be loud and still leave you with no sense of which thing matters.
There is a second gap underneath it. Error tracking only sees errors. A checkout that is slow but not broken, a background job that quietly stops, a database pool that saturates under load, a third party API that starts returning bad data with a 200: none of these throw a clean exception, so the tracker stays silent while users feel it. Seeing them means pulling logs and traces and connecting them, this error spike lines up with that deploy, which lines up with this slow query. That correlation is the work error tracking does not do, and the work a small team can least afford to do by hand.
So the question is not really which error tracker to buy. It is whether you want a better list, or a tool that reads the list for you, works out what broke and who it is hitting, and tells you the one thing to act on. That is the gap we cover in observability without dashboards, and it is what Fixter is built to do.
Seer autofix vs investigate, not fix
Sentry's direction with Seer is to act on the code: it analyzes an error and proposes a fix, often as a pull request, priced at $40 per active contributor per month.2 For some teams that is the appeal. Fixter is built on the opposite stance, and the contrast is the clearest reason to choose between them.
Fixter investigates and proposes, but it does not edit your code. When something breaks, it pulls the relevant logs and traces, identifies the root cause, and maps who is affected, since when, and how badly. Then it hands you that investigation in your editor, validated against your code, and you decide and guide the fix. It never needs access to your repository, so your code stays yours.
The reasoning is simple. An autofix is only as safe as its understanding of intent, and on a small team the person who understands intent is right there. What they lack is time to do the investigation. So Fixter does the part that is slow and mechanical, the log reading, the correlation, the impact assessment, and leaves the judgment, the part that needs a human, to the human. You already use AI to write the code. This is using it to keep the code running, without handing over the wheel.
Key takeaways
- The usual reason to leave Sentry is not price ($26/mo Team is cheap); it is that it shows you errors without telling you which matter or what to do, and small teams have no time to triage the feed
- GlitchTip is the best open source, Sentry-SDK compatible tracker: free for 1k events, $15/mo for 100k
- Honeybadger ($26/mo, flat) is the most predictable like-for-like; Rollbar and Bugsnag price on usage
- Event-volume billing means a bad release can blow a 50k quota in minutes; spike protection caps the bill but you go blind
- Error tracking also misses anything that does not throw: slow endpoints, stalled jobs, saturated databases
- Seer acts on your code at $40 per contributor; Fixter investigates, tells you what to act on, and leaves the fix to you
Frequently asked questions
What is the best Sentry alternative?
GlitchTip is the best open source option, Sentry-SDK compatible and $15 a month for 100,000 events. Rollbar, Bugsnag, and Honeybadger are the closest like for like error trackers, and Honeybadger is $26 a month with unlimited users. Fixter is the alternative if the problem is not error tracking itself but that you never have time to act on the errors, because it investigates what broke and tells you what matters instead of handing you a longer list.
Why do teams move away from Sentry?
Usually not because the error tracking is bad. It is because Sentry shows you that something is wrong without telling you which issues matter or what to do, so on a small team the error feed becomes a tab nobody opens. Some teams also leave over event-volume billing, where a noisy release burns through quota fast.
Is there an open source alternative to Sentry?
Yes. GlitchTip is open source and Sentry-SDK compatible, free to self host and free for 1,000 events a month on its cloud. Highlight is open source under Apache 2.0. Sentry's own code is source-available under a fair-source license, but self hosting the full platform is heavy, it needs at least 16GB of RAM and is unsupported at scale.
How much does Sentry cost?
The free Developer plan includes 5,000 errors a month and one user. The Team plan is $26 a month with 50,000 errors and unlimited users, and Business is $80 a month. You pay overages on event volume beyond the plan, and Seer, the AI fix feature, is a separate $40 per active contributor per month.
What is Sentry Seer and what does it cost?
Seer is Sentry's AI agent that analyzes an error and proposes a code fix, often as a pull request. As of 2026 it is priced at $40 per active contributor per month, where an active contributor is any user who makes two or more pull requests to a Seer-enabled repo that month. It is billed separately from your plan.
What is the difference between Sentry and Fixter?
Sentry tracks errors: it captures exceptions, groups them, and shows you the stack trace. Fixter investigates: when something breaks it pulls the related logs and traces, finds the root cause, and maps who is affected, then hands you the conclusion. Seer acts on the code with a proposed fix, while Fixter proposes the diagnosis and leaves the fix to you.
Can I keep my Sentry SDK if I switch?
It depends on the target. GlitchTip is Sentry-SDK compatible, so you can often repoint your existing DSN and keep working. Moving to a broader platform usually means instrumenting with OpenTelemetry. Note that Sentry's own OpenTelemetry support is partial: traces and logs are in beta and metrics are not supported.
