Libertree

Libertree is free, libre, open-source software which is intended to provide a way for people to create their own social network. Libertree social networks can be free from commercial influence and manifestation, such as behaviour tracking, user profiling, advertising, data mining and analysis, and covert information filtering.

The Libertree Project is a community of people committed to empowering the people of the world to do things on and with computers, without need for or interference from big business, by way of providing software and other tools which can be obtained, bought or built with minimal cost and effort.
