Huddle uses extensive list of open source libraries and tools, and I love it.
This is the list of things I discovered so far.
- Of course, .NET and C# for server-side language
- Castle Windsor for IoC
- Openrasta for api layer
- rabbitmq and msmq for messaging
- redis for cacheing
- Knockout JS
- Crossroads.js for client-side navigation
- Sublime Text 2 and sublime package control
scripting, build, ...
- Powershell for build
- rake for build script
- Team city for build server
- TortoiseSvn, Git for source control
- Custom NuGet Hosting
To be continued ...
