Anubis is a software program that adds a JavaScript-powered proof of work challenge to websites before users can access them, as a form of deterring the impacts of web scraping from bots. It has been adopted mainly by Git forges and free and open-source software projects.^[4]^[5]

It was created by Xe Iaso in response to Amazon's web crawler overloading their Git server, as it did not respect the robots.txt exclusion protocol and would work around restrictions.^[4]^[6]

It is used by a number of projects, including:^[7]

The GNOME Project's GitLab instance^[4]
The Linux kernel mailing list archives^[1] and Git server^[8]
sourceware.org^[7]
FFmpeg^[1]^[6]
FreeBSD
Wine^[9]
UNESCO^[6]
The Science Olympiad Student Center^[9]
Enlightenment^[9]
FreeCAD^[10]
Krantenbank Zeeland
ScummVM^[11]
