Discover Flask errors in real-time

Flask errors are tracked by Rollbar instantly as they occur. Get a real-time feed of all errors — including unhandled exceptions — so you never miss a bug.

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.

Flask error reporting with Rollbar

Get Error Context Fast

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

After setting up pyrollbar with Flask, get stack traces, request parameters, local variables, affected users and IP addresses, browsers and OSes, deployed code versions, and more.

Flask error logging

Debug Faster

Local variables and arguments help you report and debug Flask errors faster by showing you the state of the application when the error was created.

You can view their values directly from the stack trace, and know exactly how to reproduce an error locally because you can see what triggered it.
