Threema – Secure and Private Messenger

I think Threema seems like it might be a solid alternative to Signal.

A couple of other drawbacks for Threema:

- Can’t delete messages on recipient devices (disappearing messages in Signal)

- As far as I can tell, the server isn’t open source

Also, a very brief look suggests the two most recent security audits for Threema only covered the iOS & Android clients? Someone correct me if I am wrong

Threema run & operate all their own servers - that’s good & bad in my eyes (do they know what they doing? Has any of their infrastructure been security audited?)

That could be said of Signal too, since updates to the server source code haven’t been published for a very long time now (unlike the client’s source code).

Exactly, which is why one should use Matrix instead.

Afaik that's not different to Signal.
