anubis

Why we included this project

Anubis sits in front of your site as a self-hosted reverse proxy and hands every incoming request a proof-of-work challenge. That makes scraping expensive for AI crawlers and bot harvesters, while real browsers pass through with little friction. It's written in Go and light enough to run on modest hardware, so small sites, personal blogs, and community projects can use it without leaning on a commercial CDN like Cloudflare. The challenge difficulty is configurable, and bot policy definitions let you allowlist known-good crawlers such as the Internet Archive, so you can keep your site discoverable while still slowing down automated traffic. If you publish content you don't want vacuumed into training data, this is a focused tool for that job, not a general security suite.
