Tor is a publicly accessible, free software-based system for anonymizing Internet traffic. Tor relies on thousands of computers around the world called relays, which route traffic in tricky ways to dodge spying. The more relays, the stronger and faster the network. That's where you come in:

Start a relay and register it with the Tor Challenge! It's easy and works on all operating systems, including the best one — GNU/Linux.

Tor is used by journalists, political dissidents, and everyday folks around the world. In fact, it was used by Edward Snowden for his famous leaks. The FSF is proud to run our own Tor relay as well.

We've long been supporters of Tor, and we're pumped to join our allies in promoting it. As we write this, there have already been 128 new relays set up since yesterday. Let's help them double that!
