About Airbrake
Airbrake collects errors generated by other applications, and aggregates the results for review.
Errbit is an open source, self-hosted error catcher. It is a tool for collecting and managing errors from other applications. It is Airbrake (formerly known as Hoptoad) API compliant, so if you are already using Airbrake, you can just point the airbrake gem to your Errbit server.
