I've never used it but as it appears to be made by the same guy that made password store[1] (i.e. "pass") then I've got a default high opinion of it. Will definitely be checking it out.

Try out RhodeCode it focuses on Source Code Management with strong security and performance. Should be also a fast alternative.
cgit is nice, but it’s too reminiscent of the old CVS web interfaces for a lot of developers. Gogs (and therefore gitea) aimes to replicate the look and feel (and thereby the interactivity and ease-of-use) of GitHub from the start.
