Free-Ed.Net
The original free education website since 2008.

Created in 2008, Free-Ed has grown into one of the web's longest-running open education resources.

The goal of this emerging structure of education is not to pass exams and to get certified, but to grasp the essence of particular areas of knowledge for a variety of purposes ... ideas that are meaningful and of awesome value.


Free-ed.net, with tens of millions of pages served globally, was built over the course of 20 years by a single individual. Since the founder's passing, the site has been funded and maintained by family to keep his work available to learners everywhere.

Free-Ed's founder, David L. Heiserman was self-taught and the epitome of life-long learning. Despite not having a college degree, he authored over 40 books and was a 1970s pioneer in the fields of AI / Machine intelligence, Robotics and Video Game system design.

With little to no advertising revenue, the family has been funding and maintaining the site themselves since his passing in 2020. If you have benefited from this site or are otherwise so inclined, donations are welcomed here:
