Interesting approach using Postgres as the storage layer. Curious how you're handling the object model since Git's content-addressable storage maps pretty differently to relational tables. Are you storing blobs as bytea or going with something like a JSONB tree structure for the commit graph?

Nice idea.

Interesting idea but what's the use case for this? Why wouldn't I just create a private git server (gitlab, forgejo, etc) just for myself?

Just use Fossil at this point.

"doesn't support: ... Web UI."

So, it's a git server with an interesting storage layer? Don't get me wrong, that part sounds like it might have been a ton of work to implement, but I think the web UI (pull requests, etc) is a lot of what Github has won on historically.

Basically I don't feel qualified to judge the product itself, but I think positioning it against Github, while popular given the recent hard times, isn't quite correct.

Great idea

just use ssh and git bare.

This is really cool. PG has zlib compression on TOAST objects so this should still be okay even if you are not storing pack files. I am curious with your choice of hand-rolling pktline, upload-pack and receive pack implementations including rev-walking. Any particular reason you did not want to use libgit2 or something like the gitoxide implementation of pkt-line. Was it performance or is it because you wanted it to be in pure rust? Did you try running this on slightly heavier repository with a lot of commits, refs and objects?

No license?
