SimpleX Chat is the first messaging platform that has no user identifiers, not even random numbers. The messages are e2e encrypted, and the servers and network observers cannot see users’ contacts or groups. You can use the servers pre-configured in the apps or host your own.

What’s new in v4:

  • local database encryption with passphrase.
  • improved stability of chat groups, file transfers and message delivery.
  • you can now use your own WebRTC ICE servers for audio-video calls.
  • German language in the interface.
  • TypeScript SDK for SimpleX Chat integrations.

See full release announcement for more details.
