The Tor Project is a 501(c)(3) nonprofit organization. We develop free and open source software for privacy and freedom online, protecting people from tracking, surveillance, and censorship. The Tor Project’s mission is to advance human rights and freedoms by creating and deploying free and open source anonymity and privacy technologies, support their unrestricted availability and use, and further their scientific and popular understanding.
Tor protects you by bouncing your communications around a distributed network of relays run by volunteers worldwide: it prevents somebody watching your internet connection from learning what sites you visit and it prevents the sites you visit from learning your physical location. Tor works with many of your existing applications, including web browsers, instant messaging clients, remote login, and other applications based on the TCP protocol.
The easiest way to use Tor is in Tor Browser, which adds additional privacy protections to your browsing experience. Tor Browser protects against cross-site tracking with first-party isolation and browser fingerprinting. Using Tor can also help you access an open web if you're in a part of the world or on a network where sites are blocked.
