See the exception, the release, and the user.

Put this on the app as soon as someone else can hit it. It is how you find out what the happy path tests missed.

What it is

Sentry is error and performance monitoring. You install an SDK, and production exceptions show up with a stack trace, release, and user context. Sentry has added AI debugging features; the current feature names and which plans include them should be checked on the site.

A free developer plan exists. Team and business plans are paid and metered by errors and spans. Confirm allowances on the pricing page.

Why it ranks

  • Production error tracking with stack traces
  • SDKs for the frameworks builders actually ship
  • Free developer plan

Watch outs

  • Event quotas are the bill
  • It tells you what broke. It does not replace tests
