Get JavaScript exception & crash reports in real-time.
Track & debug JavaScript bugs in record time.

Real-time error reporting

JavaScript errors are tracked by Rollbar instantly as they occur. Get notified of errors and how to fix them throughout the software development process.

Similar errors are automatically grouped using Rollbar's fingerprinting technology to reduce noise, and all errors include detailed data to help you assess impact and assign priority.

Error details & metadata

Rollbar automatically collects all the data you need to replicate and debug an error, presented in ways optimized for debugging speed.

Works with JavaScript source maps.

Get stack traces, request parameters, local variables, affected users and IP addresses, browsers and OSes, deployed code versions, and more.

Telemetry for faster debugging

With Telemetry, you can debug client-side JavaScript errors faster. It works like a black box recorder, but for errors.

Get a timeline of browser events leading up to the error, including page loads, user actions, network activity, console logs, and more.

Works with your stack

Rollbar supports all popular languages and frameworks:
