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.

    I’ve did some more digging.

    and Briar still remain better at security level !

    The big downside of SimpleX is that it’s not P2P and IP correlation by watching your traffic is possible.

    SimpleX recommend to use Tor on top of it with for example Orbot. That’s a good idea, but not the best to convince none-tech folks to adopt it. (it’s already so hard to change peoples habit… ) Tor should be embedded.

    As soon Tor is embedded I will migrate to it. SimpleX have nice thought features and it’s easy to use.
