While we where working on our latest startup (omnipasteapp.com) we needed a way to get reports on application crushes from our early adopter. Existing solutions where either to expensive for a startup or did not had support for all the platforms we needed.

So we created bugfreak used a couple of weeks and then opensourced it:

https://github.com/agilefreaks/apibugfreak - the api and web app, same app as www.bugfreak.co so you can fork it and deploy it on your own server

https://github.com/Agilefreaks/winbugfreak - the .net clients (wpf, silverlight, aps mvc)

https://github.com/Agilefreaks/droidbugfreak - the android client

All packages are available in nuget and maven

As always PR are more than welcomed. Let us know what platform you want to have support for next (rails is already on the roadmap)
