Is it currently possible to completely self-host ATProto and interact with BlueSky users? (lemmy.world)

I don't actually want to do this right now, but I do want to know if it's really decentralized yet. Completely looks like it means each of:

  • A client ✅
  • A personal data server ✅
  • A relay ❓
  • Labelers ✅
  • Feed generators ✅

It looks like the relay might be the bottleneck. If I'm understanding the protocol correctly, a relay could consume less than the whole network so it doesn't have to be ridiculously expensive to operate, but I'm not finding examples of people doing it.

This is a good breakdown. A firehose relay takes TB's of storage and is not practical for self-hosting, and AppView isn't hostable yet: https://alice.bsky.sh/post/3laega7icmi2q

That's enlightening. It links to an article about self hosting a relay, which explains that, as I suspected, a relay does not have to mirror the entire network. It also seems that using a relay at all is an optional optimization.

It looks like the BlueSky AppView is not (yet?) open source. I wonder why nobody has built an alternative yet.
