Eurosky has launched "Mu", their Bluesky webapp: https://eurosky.tech/news/mu-launch/
Right now it's a fork of the Bluesky social-app project with some additions, but those additions include e.g. post editing. They're planning to be adding more new features quickly.
(Inb4: yes, for now they're still relying on Bluesky AppView server. For now.)
