## What it is
A Lua-based Anti-DDoS script for Nginx that presents a Cloudflare-style JavaScript authentication puzzle to filter out bots and mitigate Layer 7 DDoS attacks. It includes WAF features such as IP/User-Agent blacklists, rate limiting, and POST data inspection.

## Use cases
- protect nginx from ddos attacks
- mitigate layer 7 flooding without cloudflare
- block bad bots and scanners on nginx
- add an under attack mode challenge page to my site
- rate limit abusive ip addresses on nginx
- filter malicious post data with a waf
- self-host ddos protection for video streaming sites

## When to choose
- you self-host nginx/openresty and want free DDoS mitigation without a proxy service
- you need Cloudflare-style interstitial challenge pages on your own infrastructure
- you want WAF features like IP whitelisting, User-Agent filtering, and POST inspection built into nginx

## When to avoid
- you use a web server other than nginx/openresty
- you need managed, network-layer DDoS scrubbing at massive scale
- you cannot run Lua modules in your nginx build

## Facets
