Discover Sinatra errors in real-time

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

Similar Sinatra 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

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

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

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

Debug Faster

RQL (Rollbar Query Language) allows you to perform data analysis and build custom reports on your Sinatra 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.

Rollbar provides what you need to deploy and debug your Sinatra app ready for production.
