SafeLine

A community web application firewall (WAF) built on Nginx that protects sites from common attacks like SQL injection, XSS, and bot traffic.

About SafeLine

SafeLine is a free, open source web application firewall (WAF) developed by Chaitin Tech. It sits in front of your web servers and inspects incoming HTTP traffic, blocking malicious requests before they reach your application. The software uses an enhanced Nginx engine with semantic analysis engines to detect and stop SQL injection, cross-site scripting, path traversal, and other OWASP Top 10 threats without relying solely on signature matching.

Configuration is handled through a web-based dashboard where you can manage multiple sites, view blocked requests, and adjust protection policies. SafeLine also includes a rate limiting module to defend against brute force login attempts and DDoS attacks. It integrates with common reverse proxy setups and supports Let's Encrypt for automatic TLS certificates. The project is maintained on GitHub under a GPL-2.0 license and runs on Linux.
