SimpleX Chat is a private messaging platform and set of mobile/desktop apps that operate without any user identifiers, delivering end-to-end encrypted messages, files, and audio/video calls over a decentralized relay network. It includes a terminal CLI, self-hostable SMP/XFTP servers, and a documented chat protocol.
Use cases
- chat privately without sharing a phone number or user ID
- send end-to-end encrypted messages, files, and voice notes
- make encrypted audio and video calls
- run my own messaging relay server
- join or create anonymous groups and channels
- use a private messenger from the terminal
- avoid metadata tracking by messaging servers
When to choose
- you need messaging with no user identifiers and strong metadata privacy
- you want self-hostable servers and an open, audited protocol
- you need multi-platform apps plus a CLI client
When to avoid
- you need large group calls or mainstream social features
- your contacts all use WhatsApp/Signal and interoperability matters more
- you need a lightweight library to embed rather than a full app
