If you're looking for an alternative, I'm building flotilla.social, a self-hostable chat app built on nostr, which uses cryptographic identities to prevent identity capture.
Which specific use cases does this provide an alternative for? Chat is a tiny part of what people do with Discord and there are plenty of options already.
Nice, nostr is a way better setup than bluesky imo. The way you just roll your identity like you roll a bitcoin wallet. Love it. I'll keep an eye on your app.
Edit: it does look a little too corporate for me though with the 'book a demo' and the focus on my 'mission'. Doesn't really give hanging out with friends vibes. Just saying.
