Sentry

Sentry captures errors with full stack traces, breadcrumbs, and context — the request that triggered it, the user who hit it, the release that introduced it. When something breaks in production, Sentry tells you exactly where and why.

The release tracking is the underrated feature. Tag deployments, see which release introduced a regression, and resolve issues that auto-close on the next deploy. We use Sentry across frontend and backend services. The integration with React, Node.js, and Rust covers the full stack with minimal setup.
