## What it is
Anubis is a Go-based web proxy middleware that weighs the 'soul' of incoming HTTP requests using proof-of-work challenges to block AI crawlers and bots. It sits in front of websites and lets legitimate browser users through while filtering automated scrapers.

## Use cases
- block AI crawlers from scraping my website
- stop bots from hammering my self-hosted server
- add a proof-of-work challenge to incoming HTTP requests
- protect open-source project forges from aggressive scrapers
- filter automated traffic without a paid CDN
- reduce server load from AI training data collection

## When to choose
- you self-host a web service being scraped by AI bots
- you want a lightweight, self-hosted alternative to Cloudflare bot protection
- you can tolerate a brief JavaScript/proof-of-work check for human visitors

## When to avoid
- you need to allow API clients or non-browser automated access
- your users include browsers without JavaScript
- you need full WAF/DDoS protection rather than crawler filtering

## Facets
- artifact type: service
