Movim - A GPL, federated E2EE Text Chat & Video Call platform (w/ screenshare!) using XMPP just launched a new funding campaign to accelerate development of Discord-like features!

Direct link to the funding campaign to help accelerate the development of Discord-like features, such as servers with rooms/spaces, as well as drop-in voice channels.

It's quite an impressive little app capable of:

• Excellent text chats with file upload support, including solid optional encryption (OMEMO, based on Signal's encryption but modified to be compatible with federation)
• Group voice/video calls with screensharing (just implemented, must use a chromium based browser to screenshare an app's audio at the moment)
• A neat integrated blogging feature for communities & individuals
• a fun built-in paint program to easily annotate documents or draw stuff into the chat
• Full working and proven federation thanks to the XMPP back-end, which allows it to scale up reliably and easily self-host (XMPP is very lightweight).
• Uses the AGPL license, ensuring that corpos won't be able to take it over. It'll be community-owned forever.

In message-mode, it looks fairly similar to Discord:

The dev also posted a preview of what the new spaces feature looks like in the development branch:

Unlike Signal, Movim doesn't require a phone number email to create an account. And since it runs right in the browser, it's extremely quick to sign up and give it a test to see if it can meet your needs.

And if a Discord-alternative built on a truly open and federated protocol is something you want, consider throwing the dev a donation, or contributing with code (if you have the skills and time) or helping improve the documentation! :D

To stay updated on its progress, the !xmpp@slrpnk.net community pretty reliably posts news about it.
