May be the coolest cloud based error logger for .NET web applications. Based on the de-facto standard error component ELMAH, logging errors from your webserver requires nothing more than installing a NuGet package.
Application monitoring that's incredibly simple for developers of all skill levels. Monitor your app's uptime, and get notified promptly when things aren't looking good. Want some issue tracking with that? As well as server performance awareness?
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.
