I recently set up my own self-hosted "Knot", but haven't spent much time with other features:
https://tangled.org/h14h.com/knot
Overall, I think the platform looks really promising. The AtProto separation between Personal Data Servers, Relays, and AppViews seems like the appropriate set of trade-offs, IMO.
Being able to host my git repos as a headless, data-only server is about as painless as self-hosting can get. Compared with ActivityPub solutions (like Forgejo), it's great that I get to side-step the tedium of hosting and scaling an entire webapp when all I really care about is controlling my data.
Since the initial setup, the only ops maintenance I've had to do is bump the knot-server version and redeploy (tangled.org displays a banner warning notifying me when it's outdated).
Excited to spend some more time with Tangled on other projects and test out their other features! I'm particularly interested in their native support for jj and stacked PRs.
