SimpleX is a new platform for distributed Internet applications where the privacy of the messages and the network matters most.
The current version is stable, robust and can be used from the terminal (command line) on all major desktop platforms (Linux/Mac/Win) and on Android phones in Termux!
There is currently no messaging application that respects user privacy and guarantees metadata privacy — in other words, messages could be private, but a third party can always see who is communicating with whom by examining a central service and the connection graph. SimpleX, at its core, is designed to be truly distributed with no central server. This allows for enormous scalability at low cost, and also makes it virtually impossible to snoop on the network graph.
