You mean https://app.wafrn.net ?
(Truth be told wafrn doesn't have its own relays… Yet? But in any case the docker stack was recently updated to point to blacksky's, and underneath it DOES talk to both ATProto and ActivityPub so you can interact with both without the need of a bridge. And before anyone gets scared, no, posts from the fediverse aren't automatically crossed over when interacted from wafrn, they are kept fedi-only; same goes for bsky posts. And also as a wafrn user you need to manually opt in to the bsky network)
Disclaimer: I am a user of my own self-hosted wafrn instance and would very much like to see it grow
