## What it is
A lightweight, high-performance web application firewall (WAF) built on lua-nginx-module (OpenResty) for Nginx. It filters requests using regex rules to block SQL injection, XSS, SSRF, webshell uploads, scanners, and CC attacks.

## Use cases
- block sql injection and xss attacks on nginx
- prevent webshell uploads
- rate limit cc attacks per ip
- block scanner user agents
- prevent backup and svn file leaks
- add a waf to openresty

## When to choose
- you run nginx/openresty and want a simple, lightweight WAF with regex rules
- you need basic protection against common web attacks without a heavy appliance
- you want per-IP CC rate limiting built into nginx

## When to avoid
- you need dynamically managed rules via shared memory or redis
- you need advanced WAF features like a commercial ruleset or machine-learning detection
- you don't control nginx configuration or can't install lua modules

## Facets
- artifact type: library
- maturity: maintenance
- function: security, rate-limiting, middleware, logging
- domain: security, web-development, backend
- platform: self-hosted
