Clients

Cinny // Web · Desktop (Windows installer) // recommended for users coming from Discord
FluffyChat // Mobile // web version exists, but the client is designed for mobile first
Nheko // Desktop // native desktop client
SchildiNext // Mobile (downloads at top of readme) // modified Element X (see below), more customization and features than in the vanilla version
Element // Web · Desktop/Mobile // reference client implementation, it's Fine™, but you may want to try the other clients; generally prefer SchildiNext on mobile

For clients other than the linked web clients, use adamski2003.lol (or https://mx.adamski2003.lol, if the client won't take the first one) as the homeserver.

There's also a list of clients available here, if you have more specific needs or just want to see what's available.

Account

You can go here to create/manage your account. If you don't have an account in my SSO setup yet, you should be able to just sign in with Discord.
