Developer-first error tracking and performance monitoring

If your application crashes and you need to know exactly what happened — the stack trace, the user who hit it, the browser they used, the sequence of events leading up to it — Sentry catches errors in real-time and gives you everything you need to fix them. It's error tracking that actually works across every platform: JavaScript, Python, Go, Ruby, mobile, you name it.

Building Blocks

Sentry Cloud is a platform — it bundles multiple capabilities into one subscription. These tools each cover one piece. Teams often assemble 2–3 of them instead of paying for the full suite.
