I installed Gogs after a few repos I planned to use on GitHub disappeared without explanation, and after Microsoft's acquisition of same, it made me think about the over-centralization of community-developed software. A self-hosted solution that enables easy point-and-click mirroring of important repositories for my projects, both in-house and 3rd-party, ensures I won't be bitten by upstream catastrophes. (So far, Microsoft's stewardship has been fine, but always be prepared). It's also a very nice way to host one's own private repos before they're ready for prime-time on github.
Gogs is written in Go and is easy to install and configure, much more so than GitLab. The only major feature I wish it had is an integrated code review tool.
