The Tor Project, Inc, became a 501(c)3 nonprofit in 2006, but the idea of “onion routing” began in the mid 1990s.
Just like Tor users, the developers, researchers, and founders who’ve made Tor possible are a diverse group of people. But all of the people who have been involved in Tor are united by a common belief: internet users should have private access to an uncensored web.
The Tor network, which is free and open source, provides its users with online anonymity, privacy, and censorship circumvention. Tor software is designed to bounce communications around a distributed network of relays run by volunteers around the world, thereby hiding its users’ IP addresses and enabling them to circumvent online tracking and internet censorship.
OONI was born out of the Tor Project, back in 2011.
