Airbrake Ruby is a plain Ruby notifier for Airbrake (https://airbrake.io), the leading exception reporting service. Airbrake Ruby provides minimalist API that enables the ability to send any Ruby exception to the Airbrake dashboard. The library is extremely lightweight and it perfectly suits plain Ruby applications. For apps that are built with Rails, Sinatra or any other Rack-compliant web framework we offer the airbrake gem (https://github.com/airbrake/airbrake). It has additional features such as reporting of any unhandled exceptions automatically, integrations with Resque, Sidekiq, Delayed Job and many more.

Celerbrake Ruby is a plain Ruby notifier for Celerbrake (https://celerbrake.com), a cloud-based, wire-compatible error-tracking service. It provides a minimalist API for sending any Ruby exception to a Celerbrake dashboard. The library is extremely lightweight and suits plain Ruby applications well. For apps built with Rails, Sinatra or any other Rack-compliant framework we offer the celerbrake gem (https://github.com/celerbrake/celerbrake), which reports unhandled exceptions automatically and integrates with Resque, Sidekiq, Delayed Job and many more. Celerbrake Ruby began as a fork of airbrake-ruby (https://github.com/airbrake/airbrake-ruby) and remains wire-compatible with the Airbrake v3 notice API; the default host points at Celerbrake rather than a third-party service.
