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.

      The “truly private” req really smells with “I have no threat model and don’t know what am I doing”

    Not exactly what you’re looking for, BUT the best bet would probably be jabber/xmpp. There is a server involved but you can be that server with a ras pi or an old laptop, or VPS, and with OMEMO e2ee, the server can’t see message content only “bob sends X to john.” And as the server owner you can keep no logs and trust yourself.

    simplex uses relays/servers, but incoming and outgoing messages are configured to pass through separate servers. you can see this in the network settings

      I’ll try it and give my review… but is it require to make a “jami” account on their server !??

        As I understand it, the account is on your machine only. If you delete your profile, it’s gone, unless you made backups. But I may be mistaken.

          I think your mistaken… Can someone confirm ?

          So I was eager to test Jami, but on Windows it require Windows 10… so no way --> https://itvision.altervista.org/why-windows-10-sucks.html

          anyway I gave a quick try on a test machine (win10) But I got , not matter what I entered

          Too bad because it had on paper, a lot of nice features…

          On linux, too bad they don’t provide (yet) an AppImage…

    A little update.

    I’ve just tested simplex on Android.

    it’s very well thought out ! The features make sense. UNFORTUNATELY it’s not P2P ! all the messages pass by their servers :'( with Briar it’s P2P… weirdly they claim their way is better than P2P ! any comment on that ?

    In my point of view, if messages are stored somewhere it’s mean the can be process[1] !

    Cheers.
