Yes. Haven is a personal relay and Blossom server that you can use with multiple clients. I'm not sure if Coracle is Outbox enabled ( nostr:npub1jlrs53pkdfjnts29kveljul2sm0actt6n8dxrrzqcersttvcuv3qdjynqn ), but it does have custom views where you can look only at your own outbox and inbox relays.

Other from restricting your inbox relay to your WoT, Haven allows you to keep a copy of your own notes and media, and to serve them directly instead of relying on third parties.

PS: The official version of Haven on Bitvora's repo is WoT-enabled, but I haven't merged the ownertrust + TOFU model yet. I may contribute it to the upcoming v2 if I'm confident it is stable enough for me to commit to backwards compatibility.
