Tor

Free software for anonymous communication.

Tor is free software for anonymous communication. The Tor network is a volunteer-operated set of relays that route TCP traffic through three hops, with each hop knowing only the previous and next hop in the chain. Onion-encryption layers peel off at each relay, so no single relay can see both the true source and destination of a connection.

The Tor Browser bundles Firefox with Tor for safe everyday browsing. It is the standard tool for journalists, activists, and people in countries with intrusive surveillance — situations where being traced from network metadata could have serious consequences. Hidden services (.onion sites) extend the anonymity to the server side.

Roger Dingledine, Nick Mathewson, and Paul Syverson developed the original Tor at the U.S. Naval Research Laboratory in the early 2000s. The Tor Project, a US-based 501(c)(3) non-profit, has run the project independently since 2006, funded by a mix of government grants, private donations, and corporate sponsorships. The codebase is BSD-3-Clause and the protocol is freely usable.
