Tech stack & purpose

SimpleX Chat is a messaging network designed to operate without any user identifiers, emphasizing privacy by design with applications available on iOS, Android, and desktop platforms. Built primarily in Haskell, the project encompasses a full messaging protocol stack featuring end-to-end encryption with double-ratchet key exchange. The repository includes several companion applications: a CLI chat app, customizable bot examples (including a REPL-based bot, a broadcast bot, and a support bot written in Node.js), a directory service for registering and searching groups, and web hosting utilities for directory pages. The SimpleX Chat ecosystem is maintained as an open-source project with multiple modular components designed to enable users to build privacy-respecting communication services and integrate them with other applications.
