Ditto or Wisp would be my bets

Jumble

A user-friendly Nostr client for exploring relay feeds

Probably wispy Wisp

Mutable must stay separate but interoperable for all nostr clients. Usually a nostr pro user do not use just one single client, but many.

It should be interoperable. I am interested in clients that can read and write their own Mutable-compatible events. Users could publish and subscribe to these lists from within the Nostr app of their choice.

Mutable mute packs could be a real UX unlock if clients add provenance and diff history, not just subscribe and pray. Which client team feels closest?
