I would urge all of you to spend 5 minutes trying it out. You can use the public server operated by the project https://nine.testrun.org or feel free to try my server, but I've intentionally broken email federation (port 25 closed) so it's isolated right now -- https://chat.feld.me

1. Install the app. It's great, feels like old WhatsApp.

2. Create an account. You *could* use any email address, but the dedicated Chatmail servers (previously mentioned) are specially configured for performance and will generate random pseudonymous accounts for you. You don't even have to set a password or choose a username. It's instant provisioning in the app.

3. Make a group chat, share the QR code or link and try it out.

Extremely low resource requirements, you can host hundreds to thousands of users on a Raspberry Pi. Ephemeral messages. Accounts auto delete after 90 days of inactivity by default. Extremely short log retention. Working Push notifications for iOS and Android cleverly design to ensure they can't be tied to the user account.


Other features:

- copy accounts between devices (phone/desktop) with a QR code/link if you're on the same local network
- location sharing
- voice messages
- image/video attachments
- video chat integration with 3rd party services (i've never tested it though)
- embedded WebXDC apps in the chat (pretty cool single-file apps that can allow realtime p2p communication between users)
- bots can be built, devs are heavy Python folks so that's what they're built in right now
