Rollbar is a real-time exception reporting service for Ruby and other languages. The Rollbar service will alert you of problems with your code and help you understand them in a ways never possible before. We love it and we hope you will too.

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

Setup Instructions

  1. Sign up for a Rollbar account
  2. Follow the Getting Started instructions in our Ruby SDK docs to install rollbar-gem and configure it for your platform.

Usage and Reference

For complete usage instructions and configuration reference, see our Ruby SDK docs.


Version >= 3.0.0 is compatible with Ruby >= 2.0.0.

Version >= 2.19.0 is compatible with Ruby >= 1.9.3.

Version < 2.19.0 is compatible with Ruby >= 1.8.7.

Ruby 2.6.0

WARNING: Ruby 2.6.0 introduced a new bug bug (#15472 - Invalid JSON data being sent from Net::HTTP in some cases with Ruby 2.6.0) that may result in the Rollbar API returning an error when an exception is reported. (See rollbar-gem issue #797).

UPDATE: This bug is fixed in Ruby 2.6.1, and rollbar-gem has a safe workaround in version >= 2.19.0. If you need to stay on Ruby 2.6.0 for any reason, make sure you have the latest rollbar-gem.
