Aside from Discord, nobody has gotten this right since Yahoo! Live and Tinychat. Both are dead.

If an option doesn't have that then it's not a Discord alternative for me or many of my friends.

You might be interested in https://kloak.app I believe. It's a privacy-first alternative. It's still in early alpha days, but have most of the things set up. Oh, and we’ve got voice channels with screen sharing in beta too.

How do you plan on funding it? Also, the landing page mentions "You own your community data" but it just looks like you own it and allow us to access it?

Seems to me you're just re-building discord.

"Messages are stored on our servers and are technically accessible at the database level , we won't pretend otherwise. Kloak doesn't require email, phone, or personal info to create an account, your identity isn't tied to your messages the way it would be on other platforms.

Our goal is to implement end-to-end encryption for DMs so that even we can't read message content. But we're not there yet, since after all we need to make sure the platform is safe and not to shield illegal content being sent."

This is a message from one of their founders I found while exploring the app.

Why would they name their software sewer?
