Tinode is meant as a replacement for XMPP. On the surface it's a lot like open source WhatsApp or Telegram.
The promise of XMPP was to deliver federated instant messaging: anyone would be able to spin up an IM server capable of exchanging messages with any other XMPP server in the world. Unfortunately XMPP never delivered on this promse. Instant messengers are still a bunch of incompatible walled gardens, similar to what AoL of the late 1990s was to the open Internet.
The goal of this project is to actually deliver on XMPP's original vision: create a modern open platform for federated instant messaging with emphasis on mobile communication. A secondary goal is to create a decentralized IM platform which is much harder to track and block by the governments.

A text-only command line client implements every possible command.
The demo server is reset (all data wiped) every night at 3:15 am Pacific time. An error message
User not found or offlinemeans the server was reset while you were connected. If you see it on the web, reload and relogin; on Android delete the app then reinstall.
As generally accepted, when you register a new account you are asked for an email address. The server will send an email with a verification code to that address and you can use it to validate the account. To make things easier for testing, the server will also accept
123456as a verification code. Remove line
tinode.confto disable this option.
The demo server is configured to use ACME TLS implementation with hard-coded requirement for SNI. If you are unable to connect then the most likely reason is your TLS client's missing support for SNI. Use a different client.
