Anubis

Web AI firewall that protects sites from scraper bots

About Anubis

Anubis is a web AI firewall utility that protects upstream resources from scraper bots by weighing the soul of each connection with a SHA-256 proof-of-work challenge. It sits in front of a web service as a reverse-proxy layer, challenging automated clients while letting real browsers through, so large-scale scraping becomes expensive. Written in Go and released under the MIT license, it is aimed at site operators, especially open-source projects and forges overwhelmed by aggressive AI crawlers.
