sr.ht - open source software suite for managing software projects
An alpha version of sr.ht has just been announced publicly. It's an open source software combining hosting of source code with continuous integration, mailing lists, a bug tracker, manuals and more.
The individual components (git, CI, lists, ...) are provided as standalone applications which integrate with each other. This modular approach makes it possible to mix and match the solution with third parties.
As usual a hosted solution is available and the application can be run on own hardware for those who wish to stay in control of their data.
