A real messenger, not a mentions tab.
Social web DMs are posts with the audience turned down. Sup gives them chat bubbles, group chats, typing and calls, without asking anyone to leave their server.
Private on Sup
When you're both on Sup, switch a chat to skip federation: typing, read receipts and faster delivery. Your server doesn't see those messages.
The fun stuff
GIFs and stickers, reactions, voice and video calls, and Vanishing mode, which clears messages after 24 hours.

Questions
Do I need a new account?
No. You sign in through your own social web server and approve Sup there. Your handle, your followers and your server stay exactly as they are.
Which servers work?
Mastodon and servers compatible with its API, plus Pixelfed and Loops.
Do I have to post publicly to get in line?
No. You can send @sup a direct message with your link instead. On Pixelfed and Loops, where every post needs a photo or video, that's the easiest way.
Is it end-to-end encrypted?
Not in the first version. Messages are encrypted in transit and stored on our servers in Canada. We'll say so clearly when that changes.
Can I host it myself?
Yes. Sup will be open source when version 1 ships, and you'll be able to run your own Sup Server.
When can I use it?
Sup arrives in 2027. People on the waitlist get early access first, in the order they got in line.
