## The Hook

Anubis sits in front of your reverse proxy and makes scrapers pay SHA-256 before the origin does.

## What's Good

MIT. Go binary proof-of-work gate for Caddy/Traefik/nginx-style frontends. Policy allowlists for good bots. Docs at anubis.techaro.lol.

## The Catch

PoW slows mass scrapers; determined headless solvers still pass. Can impede Archive/RSS unless you allowlist. Not Cloudflare WAF. Distinct from Traefik/Caddy proxies.

## Verdict

MIT anti-scraper PoW layer. Free forever; tune policies.
