JavaScript error logging with Rollbar

Instantly know when JavaScript errors occur and how to fix it

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

Real-time error reporting

Get notified of JavaScript errors instantly as they occur after deployment - and before users notice.

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.

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.
