Hi,

I’m looking for an instant messaging ( IM ) apps software/protocol that run on Android and computer

and meet the following requirements :

  • Open source !
  • E2EE
  • Messages are send in direct ! (not passing by a server)
  • handle group
  • Truly private ! ( That’s the tricky part )

 

The closest that I’ve found is Briar

  • +can work without internet ! (bluetooth, local wifi, files !)
  • + use TOR
  • - Mutual party have to exchange key (or your can introduce someone)
  • - sending media suck for now, poor image quality
  • - no call or voice messaging

 

I’ve been looking for alternatives:

  • Session
    • Sadly it keep ALL the conversation into server !!! so it’s a no go.
  • speek
    • I didn’t try it yet, any feedback ?
  • simplex
    • it look very promising ! (didn’t tried it yet)
    • + seem to handle multiple profile in one !
    • + do not require that both party send an invitation !
    • ! I didn’t found (yet) if the messages are send in direct or pass by a server…
      It’s not P2P all the messages pass by servers… too bad.

All post about alternatives or experience with the one that I cited are welcome.

    SimpleX uses servers, but they’re just relays and due to SimpleX’s design, no single server can figure out who you are or who you’re talking to. By using Tor they also couldn’t band together and fingerprint you by IP.

    If you want to see the model explained, visit their website or just ask here, I’m glad to explain how it keeps your contact graph, identity and messages private :)
