https://dmitri.shuralyov.comI use it myself daily to receive a chronological feed aggregating notifications from GitHub and Gerrit. I’m pretty happy to rely on that and not need to receive notifications via email or by visiting multiple web UIs.
It also hosts my newer (though also more rare) personal Go packages, serving them via a custom implementation of the module proxy protocol in addition to a git server, an issue tracker, and most recently a simple code review system (see https://dmitri.shuralyov.com/go/generated$changes/1). Supports logging in via the IndieAuth protocol—try entering your website's URL at https://dmitri.shuralyov.com/login.
Source code is at https://github.com/shurcooL/home, though some WIP changes aren’t there yet, and I should really move it to be hosted on my personal site for more dogfooding. One day.
