You are looking for a webmail client? If so I offer roundcube to my friends and family. But they are not picky or in IT. I use Thunderbird on PC and K-9 Mail on the phone. But that's not webmail.

Is it not a big no-no to use Gitea now since the commercial takeover? From what I understand, Forgejo is the safe option and I am glad to hear from the other comments that it is getting support for that through ForgeFed!

Completely agree! Please note that git itself is federated, well distributed, it's the rest of the stuff on top that needs to be fixed.
