As regards features, git.sr.ht is certainly lighter than Gitea, but still suffers from various of the same problems because it’s designed to run the show with social operation, rather than just doing read-only publication of repositories that it finds at such-and-such a location. It doesn’t have as much extraneous and undesirable functionality (e.g. no issue tracking), but when setting it up requires PostgreSQL and Redis (which latter I think you may be able to skip, but it’s hard-required in the systemd units I see) and more… yeah, this is not what I’m looking for. Operationally, Gitea is considerably lighter than git.sr.ht, as you can get it going with only Git and SQLite installed.
