Hey everyone.
I make Peersuite, an opensource free communication platform.
It's private by default, there's no sign-in or email collection.
It's peer-to-peer, there's no server, after discovery you are connected directly to your friends my AES-GCN encrypted WebRTC channels. It forms a mesh and identifies superpeers. Because there is no server, in order to save your data between sessions, you can download your workspace into a password encrypted file. Happy to answer any questions.
FEATURES: chat with images, PMs, channels, and file send group audio/video calling screensharing kanban board whiteboard for diagrams/flowchartswith PNG export collaborative document editing with formatted PDF export
The best way for self hosting is docker, its on dockerhub as openconstruct/peersuite. You can also download desktop versions from the github or use on the web at https://peersuite.space/
That sounds pretty cool! You have listed a lot of great privacy features. I'm sure you know they will likely restrict adoption, because Grandma probably won't be able to figure it out.
It does look neat and I will give it a try.
I tried to make it super easy, but I'm not a UI guru or anything.
Hopefully gramma will figure it out, I'm a grandparent and I made it lol.
