Matrix is an open-source decentralized E2EE messaging protocol.
Here are the european instances you can sign up at:
🇬🇧 UK: matrix.org
🇫🇷 France: tendomium & imagisphe.re & hadoly.fr
🇩🇪 Germany: tchncs.de, catgirl.cloud, pub.solar, yatrix.org, digitalprivacy.diy, oblak.be, nope.chat, envs.net, hot-chilli.im, synod.im & rollenspiel.chat
🇳🇱 Netherlands: bark.lgbt
🇦🇹 Austria: gemeinsam.jetzt & private.coffee
🇫🇮 Finland: pikaviestin.fi
For desktop use Element
For mobile use Fluffy Chat
Let me know if I missed any instances and I will be sure to update the post.
I think the matrix.org servers, whilst owned by Matrix, might be actually physically located on the continent. Given the UK’s determination to kill encryption right now, I wouldn’t recommend joining an instance hosted there.
