For a 1 to 10 developer SaaS team that builds with Claude Code, Fixter is the quickest start: error tracking, logs and uptime in one, set up with one prompt, with a free plan. Sentry is the most complete error tracker, from $26 a month. PostHog and Better Stack give 100,000 free exceptions a month. GlitchTip is the cheap self-hosted option.
We checked every tool below against the vendor's own pricing page and docs on October 21, 2026, and cite them inline. Fixter is our product. It comes first because it is our pick for teams that build with Claude Code, and its section says where it falls short. Sentry follows as the one most teams know, then the rest in alphabetical order.
The eight tools at a glance
Error tracking, also called error monitoring, catches the exceptions your app throws in production, groups repeats of the same one into a single issue, and tells you when a new one appears. These are the tools that come up when a small team picks its first one.
| Tool | Free tier | Paid from | Priced by | Also covers | Self-host | MCP |
|---|---|---|---|---|---|---|
| Fixter (ours) | 10 GB a month, unlimited users | €20 a month | Data volume | Logs, traces, metrics, uptime, alerts | No | Yes |
| Sentry | 5k errors, 1 user | $26 a month, unlimited users | Events | Tracing, logs, replays, uptime, cron | Yes | Yes, plus plugin |
| Better Stack | 100k exceptions, 10 monitors | $29 per responder a month | Seats plus usage | Logs, traces, uptime, status pages, on-call | No | Yes, plus plugin |
| BugSnag | 7.5k events, 1 user | Select plan, by volume | Events | Performance | Enterprise only | Through SmartBear |
| GlitchTip | 1k events hosted | $15 a month, 100k events | Events | Uptime, performance, logs | Yes, MIT | Yes |
| Honeybadger | 5k errors, 1 user | $26 a month, unlimited users | Errors | Logs, uptime, check-ins, status pages | No | Yes |
| PostHog | 100k exceptions, unlimited users | Pay as you go, no base fee | Exceptions | Product analytics, replays, logs, flags | Yes, MIT | Yes, plus plugin |
| Rollbar | 5k occurrences, unlimited users | $9 a month, 10k occurrences | Occurrences | Session replay | Not listed | Yes |
Free tiers are per month. Lowest list price in each vendor's currency on October 21, 2026; Sentry and Better Stack billed yearly. Click a tool for details and sources.
What a small team needs from error tracking
A small team does not need every feature. It needs a short list done well:
- Grouping. The same exception should be one issue with a count, not a flood of events. This is most of the value.
- Context. A stack trace, the request, the release, and ideally the user it hit.
- Alerts for new issues, by email or Slack, so a new bug reaches you before a support ticket does.
- Pricing that does not punish seats. If adding your fourth developer costs more than your errors do, look elsewhere.
- An SDK for your stack, or OpenTelemetry support, so setup is an afternoon, not a project.
- Something your coding agent can read. If you build with Claude Code or Cursor, an MCP server lets the agent open the error and fix it in the same session. Every tool here has one.
Each tool, in short
Fixter (ours)
Fixter is ours, so weigh this section with that in mind. Fixter finds and fixes the issues in your app in production, from your coding agent: errors, failing infrastructure, slow requests and downtime. It finds the root cause and fixes it: in your agent over MCP, or as a pull request ready for your review. Nothing to learn, built for small teams.
The difference from the rest of this list: Fixter is not an error tracker with extras. Your app sends logs, traces and metrics over standard OpenTelemetry, with no Fixter SDK, and Fixter turns errors from all of them into issues: the same exception is one issue with a count, and you are alerted by email or Slack when a new one appears.1 You set it up and run it from Claude Code, over MCP.2 Free plan, with issue tracking and unlimited users. Paid from €20 a month; AI investigations are on paid plans.3
Watch for: there is no self-hosted option, and it is a younger, smaller product than Sentry. Because it works from OpenTelemetry, check that your stack, especially frontend and mobile, can send it.
Sentry
Sentry is the default most developers know from a past job, and for good reason: SDKs for almost every language and framework, strong grouping, performance tracing, logs and session replay in one place. The free Developer plan is one user, 5,000 errors, 5 GB of logs, 50 replays and one uptime monitor a month, with MCP access. Team is $26 a month billed yearly or $29 monthly, for 50,000 errors and unlimited users.4 Seer, Sentry's AI analysis, is an add-on at $40 per active contributor a month.5 You can self-host it for free under the Functional Source License, but it needs at least 4 cores and 16 GB of RAM.6 Its MCP server and Claude Code plugin are the most complete for errors.7 We compare it with Datadog's in Datadog MCP vs Sentry MCP.
Watch for: the free plan is one user, so a team of two is already on Team.
Better Stack
Better Stack puts errors, logs, traces, uptime monitoring, status pages and on-call in one web app. The free plan includes 100,000 exceptions, 10 monitors and heartbeats, and 3 GB each of logs and traces. Paid starts at $29 per responder seat a month billed yearly, or $34 monthly, plus usage.8 It accepts the Sentry SDKs, so you can point an existing Sentry setup at it, and it takes OpenTelemetry.9 It has a hosted MCP server and a Claude Code plugin.10
Watch for: pricing is per responder seat, the people who get paged, so cost grows with your on-call rotation.
BugSnag
BugSnag, part of SmartBear, is error monitoring with performance monitoring built on OpenTelemetry, and SDKs for more than 50 platforms, mobile included.11,12 The free plan is one user with 7,500 events and 1 million spans a month. Paid plans start with Select, priced by event volume with unlimited users; going over your quota does not drop events, but going over more than three times in 30 days moves you up a plan.11 Claude Code can read BugSnag through SmartBear's MCP server.13
GlitchTip
GlitchTip is open source under MIT and compatible with Sentry's SDKs, so you instrument your app as if for Sentry and point it at GlitchTip.14,15 It covers errors, uptime, performance and logs. Hosted, the free plan is 1,000 events a month with unlimited team members, and Small is $15 a month for 100,000 events; uptime checks count toward the event allowance.16 It has a built-in MCP server, running on the hosted service too.17
Watch for: fewer features than Sentry. It is the pick when you want to self-host and keep it light.
Honeybadger
Honeybadger bundles error tracking with logs, performance, uptime monitoring, cron and heartbeat check-ins, and status pages. The free plan is one user, 5,000 errors, one uptime monitor and basic check-ins. Team starts at $26 a month for 50,000 errors with unlimited users, and overage is optional at $0.0003 per error.18 It has an official hosted MCP server.19
Watch for: like Sentry, the free plan is one user.
PostHog
PostHog is product analytics first, with error tracking as one of its products. The free tier is the most generous here: 100,000 exceptions a month, unlimited team members, plus session recordings and logs on the same free plan. Above that you pay per exception with no base fee and no seats, starting at $0.00037 each.20 It can be self-hosted under MIT without support.21 It has an MCP server and a Claude Code plugin.22
Watch for: PostHog's own page says it has no uptime monitoring yet, and that Sentry is better if you need mobile support.20
Rollbar
Rollbar is error tracking with session replay and an AI fix agent. Every plan, including free, has unlimited users and projects. Free is 5,000 occurrences and 1,000 session replays a month; Essentials starts at $9 a month for 10,000 occurrences, and yearly billing costs the same as ten months.23,24 At the limit it stops processing new events by default unless you turn on pay-as-you-go.24 Its MCP server is open source under MIT.25
Watch for: no logs, tracing or uptime, so you will need a second tool for those.
Which one should you pick?
Every tool here catches and groups errors well enough for a small team. The real choice is what else you want in the same place.
- You build with Claude Code and want errors, logs, traces and uptime without learning a console: Fixter, set up with one prompt.
- Errors done properly, nothing else yet: Sentry. Start on free, move to Team when the second developer joins.
- Errors plus uptime, status pages and on-call: Better Stack or Honeybadger.
- You already use PostHog for analytics: turn on its error tracking; the free allowance is large.
- Must self-host, small budget: GlitchTip. Sentry self-hosted if you need its features and can spare the server.
- Cheapest paid plan with unlimited users: Rollbar.
- Mobile apps: BugSnag or Sentry.
If you are weighing a bigger platform instead, our Sentry alternatives and Datadog alternatives pages go deeper. And once you pick one, connect it to Claude Code so your agent can read the errors; our MCP server comparison has the install line for each.
How do you find bugs in production before your customers do?
Run three checks: error tracking that alerts you when a new issue appears, an uptime check on your main pages and API, and logs you can search when an error makes no sense on its own. A small team can get all three from one or two tools. Then act on the first alert, not the first ticket.
- Error tracking with alerts on new issues. A new exception after a deploy is the most common early warning.
- An uptime check on your main pages and API, so you hear about downtime from a check, not a tweet. More in how do I know when my app goes down.
- Logs you can search when an error makes no sense on its own: what the request did before it failed.
We go through this step by step in monitoring errors in production. For what to set up first on a new app, see what to monitor first.

Frequently asked questions
What is the best error tracking tool for a startup or small team?
For a 1 to 10 developer team that builds with Claude Code, Fixter is the quickest start: error tracking, logs and uptime in one, set up with one prompt, with a free plan. Sentry is the most complete error tracker, with SDKs for almost every stack and Team at $26 a month with unlimited users. PostHog and Better Stack each include 100,000 exceptions a month free.
Is there a free error tracking tool?
Every tool here has a free plan. The largest are PostHog and Better Stack at 100,000 exceptions a month. BugSnag gives 7,500 events, Sentry, Honeybadger and Rollbar 5,000 errors (Rollbar with unlimited users, Sentry and Honeybadger with one), and GlitchTip 1,000 hosted or unlimited if you self-host it. Fixter's free plan is 10 GB of data a month with unlimited users.
Sentry or Better Stack for error tracking?
Sentry if errors are the main job: deeper error grouping, more SDKs, performance tracing and session replay. Better Stack if you also want uptime monitoring, status pages and on-call in the same tool; it accepts Sentry's SDKs, has a larger free error allowance, and charges per responder seat.
Can I self-host error tracking?
Yes. GlitchTip is MIT licensed, works with Sentry's SDKs and is the lightest to run. Sentry self-hosted is free under the Functional Source License but needs at least 4 cores and 16 GB of RAM. PostHog can also be self-hosted under MIT, without support.
Do I need error tracking if I already have logs?
Usually yes, or a tool that does both. Logs record everything; error tracking groups the same exception into one issue with a count, keeps the stack trace and context, and alerts you when a new one appears. That grouping is what stops a single bug from becoming ten thousand log lines nobody reads.
How do I find bugs in production before my customers do?
Add error tracking with alerts for new issues, an uptime check on your main pages and API, and logs you can search when something looks wrong. Then act on the first alert, not the first support ticket. A small team can get all three from one tool or two.
Which error tracking tools work with Claude Code?
All eight in this comparison have an MCP server, so Claude Code can read your errors: Sentry, Better Stack, Honeybadger, Rollbar, BugSnag through SmartBear's server, GlitchTip, PostHog and Fixter. Sentry, Better Stack and PostHog also ship Claude Code plugins.
