ref12.io is a replacement/successor to https://referencesource.microsoft.com, http://sourceroslyn.io, https://source.dot.net, and other sites generated by SourceBrowser. Though they serve a similar function, Ref12's architecture and backend are completely different.

To browse source, simply open https://ref12.io in your browser. By default, you can navigate the dotnet/runtime and other assorted repos currently found in https://source.dot.net. A much larger set of repos is available to sponsors. Our sponsors can also request other public repos to be added to the index. NOTE: Login is required for sponsors to view the full set of repos. See full list here.

Currently, indexing private repositories is not supported.

Contact us if you're interested in self-hosting the ReF12 engine on-prem for your private enterprise. We provide a license and paid support. Your private source code stays hosted on your infrastructure.
