Anubis is a security tool that sits in front of your website and blocks AI crawler bots from hammering it with endless automated requests. Named after the Egyptian god who weighed souls to determine their fate, Anubis evaluates each incoming HTTP request and forces suspicious visitors to complete a challenge before they're allowed through, much like a CAPTCHA, but specifically designed to stop AI data scrapers. The problem it solves is real: AI companies send automated bots that crawl websites constantly, consuming bandwidth and server resources at a scale that can overwhelm small community sites, forums, and indie projects. Anubis acts as a reverse proxy (a gatekeeper that all traffic passes through) and challenges connections that look like bots before they reach your actual server. You'd use it if you run a website you want to protect from AI scraping, especially if you can't or won't use Cloudflare. The project itself calls it "a nuclear response", it will also block smaller legitimate scrapers like archive bots unless you explicitly allow them via configuration. It's designed to be lightweight so small communities can afford to run it. The tech stack is Go.
