Discover Express errors in real-time

Express errors are tracked and logged 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.

Get Error Context Fast

Rollbar automatically collects all the data you need to log, replicate and debug an Express 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.
