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.

plaintxt is private, anonymous E2EE messaging for conversations that should not become permanent threads.

Create a temporary browser-based identity and start messaging without an account, email, phone number, or real name. Messages burn after reading, unread messages expire automatically, and attachments are temporary too.

plaintxt is built for private citizens, creators, online sellers, communities, founders, and privacy-conscious users who want secure communication without profiles, contact lists, or unnecessary data trails.
