The Tor Project is a 501(c)(3) nonprofit. Our mission is to advance human rights and freedoms by creating and deploying free and open source anonymity and privacy technologies, supporting their unrestricted availability and use, and furthering their scientific and popular understanding.

We develop free and open source software for privacy and freedom online, protecting people from tracking, surveillance, and censorship—the Tor network and Tor Browser. The Tor network is a decentralized privacy network designed to help people exercise their human right to privacy, freedom of speech, and access to information. Millions of people use the Tor network every day, most through Tor Browser, a privacy-hardened version of the open source web browser Firefox.

The Tor network, Tor Browser, and all other software, tools, and documentation produced by the Tor Project are free and open source. The Tor network and Tor Browser are designed to be used, built, and stewarded by a large community with different interests, needs, and perspectives. The Tor network is volunteer-run, with thousands of community members donating server capacity to create a piece of collaborative infrastructure that is free to use.
