Anubis is a protective system designed for website administrators who need to defend their servers against aggressive, automated scraping, particularly from AI companies. It acts as a gatekeeper, presenting a lightweight proof-of-work challenge to incoming traffic to filter out bots while allowing legitimate human users to pass.

Proof-of-Work Challenge: Visitors must solve a small computational task, similar to Hashcash principles. This adds negligible cost for individual users but becomes prohibitively expensive for mass-scale scraping operations.

Server Protection: The primary goal is to reduce server load and prevent downtime caused by overwhelming bot traffic, ensuring resources remain accessible for real users.

Future Development Focus: The current system is a transitional measure. Ongoing work is dedicated to improving fingerprinting techniques to identify headless browsers, aiming to eventually present the challenge only to likely bots.

Technical Requirements: It relies on modern JavaScript features to function. Visitors using privacy or security plugins that disable these features, such as JShelter, will need to adjust their settings for the specific domain to proceed.

Transparency: The version of the system running is openly displayed, providing administrators and users with clear information about the implementation.
