Errbit vs. Airbrake vs. Errorception

Errbit 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.

Airbrake collects errors for your applications in all major languages and frameworks. We alert you to new errors and give you critical context, trends and details needed to find and fix errors fast.

Errorception is a simple and painless way to find out about JavaScript errors, as they occur in your users' browsers. All you need to do is insert a script tag on your page, and you will start recording errors as they happen in real-time.
