Vixrapedia is a collaborative online knowledge archive focused particularly on the sciences. It describes itself as a free, non-censored resource where anyone can create or edit articles and share ideas. The site offers an alternative publishing space for contributors who find it difficult to present their work through more restrictive encyclopedias or conventional academic channels. It is not affiliated with Vixra, though it encourages Vixra authors and other alternatively published scientists to contribute alongside publishing technical papers elsewhere.

Visitors can search existing articles, create pages, and edit content, with guidance available through the site’s editing help and policy pages. Its collection includes topics such as quantum space complexity, lattice QCD, foundations of mathematics, physics, and knowledge construction in education and research. Vixrapedia also features recent changes, random pages, and information about partner organizations. The site presents itself as part of a community supporting open, censorship-free academia, education, and research.
