@Heliograph @davidv @jikomayo @adamhsparks #session started as a fork of #signal that is designed to run over an #onionrouting system. It has more privacy features than most messaging networks have. Both the server and the client are open-source.
I've been using #session for a couple of years now that #wickrme shutdown. In general, it it is good. It had a rough time for a while as it was Target targeted my a multi-month long #ddos attack, but those have seem to be resolved over 9 months ago.
