Monitor Rails errors in real-time

Add the Rollbar-gem to your Rails projects to automatically capture and report errors in your applications.

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

Ruby on Rails error monitoring with Rollbar

Get Error Context Fast

Our tool automatically collects all the data you need to monitor, replicate and debug a Rails error, presented in ways optimized for debugging speed.

Rollbar-gem is the SDK for Rails apps and includes support for apps using plain Ruby, Sinatra, Rack, and other frameworks.

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

Track Rails error faster

Debug Faster

RQL (Rollbar Query Language) allows you to monitor, perform data analysis and build custom reports on your Rails error data, using a familiar SQL-like language.

You can use RQL to get answers to very specific questions, e.g. “How many users are getting by 404 errors right now, grouped by referring URLs?”

RQL is also accessible via API.
