XMPP has been used by privacy-conscious users for decades, but running a server on the clearnet still exposes metadata. Hosting on Tor solves this:
- Server anonymity - The .onion address hides your XMPP server's location and operator identity
- User anonymity - Members connect through Tor, hiding their IP address from the server and network observers
- Server-to-server privacy - Federate with other Tor-hosted XMPP servers through .onion-to-.onion connections
- OMEMO + Tor - Combine end-to-end encryption (OMEMO/OTR) with transport anonymity (Tor) for maximum privacy
- No centralization - XMPP is federated by design, so no single entity controls the network
XMPP on Tor is the messaging stack of choice for individuals and organizations that refuse to compromise on communication privacy.
