IMPORTANT: Lets get a few things out of the way first. My app is not better than any other app in any way. It hasnt been reviewed or audited. This app works by exchanging IP addresses... This app is NOT for anonymous comms.

The project is experimental and far from finished. It's presented for testing, feedback and demo purposes only (USE RESPONSIBLY!).


By leveraging WebRTC for direct browser-to-browser communication, it eliminates the middleman entirely. Users simply share a unique URL to establish an encrypted, private channel. This approach effectively bypasses corporate data harvesting and provides a lightweight, disposable communication method for those prioritizing digital sovereignty.

Features:

  • P2P
  • End to end encryption
  • Forward secrecy
  • Post-quantum cryptography
  • Multimedia
  • Large file transfer
  • Video calls
  • No registration
  • No installation
  • No database
  • TURN server

This project isnt finished enough to compare to existing tools like Simplex, Signal and WhatsApp... This is intended to introduce a new paradigm in client-side managed secure cryptography. Allowing users to send securely encrypted messages; no cloud, no trace.
