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!
