Alternatives to Rollbar

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.

Full-stack monitoring: error monitoring, session replay, logging

If you need to understand what your users are experiencing when something breaks (errors, session replays, logs, traces all in one place), Highlight is a full-stack monitoring tool that captures the whole picture. Think of it as Sentry + LogRocket combined, but open source.
