Sentry is application monitoring for developers who'd rather fix bugs than hunt for them. Track issues, and regressions across your stack, then use AI-powered debugging, session replays, and traces to get to the root cause, fast.
Sentry started in 2012 as an open source error tracker built by developers, for developers. What began as a simple tool for catching Python exceptions grew into the application monitoring platform used by over four million developers and 100,000 organizations. Today, Sentry covers the full debugging workflow: errors, performance, session replays, traces, and AI-powered root cause analysis. The product is still open source at its core, and the company is still led by the engineers who built it. We process billions of events every day because developers kept showing up with more code that needed watching.
