SafeLine
What it is
SafeLine is a self-hosted web application firewall and reverse proxy that filters traffic between web applications and the internet. The maker describes its Nginx-based design as a way to block malicious HTTP traffic. Listed protections cover SQL injection, XSS, code injection, XXE, SSRF, and path traversal. Anti-bot challenges are intended to admit human users while blocking crawlers and bots; rate limiting addresses DoS attacks, brute-force attempts, traffic surges, and other abuse. A dynamic protection feature encrypts HTML and JavaScript from the web server on each visit. Integrations include an MCP Server for AI-assisted management, an Ingress-NGINX plugin for Kubernetes ingress, and a Kong Gateway plugin for APIs and services. Installation instructions call for Docker and Docker Compose V2 on the host. SafeLine is available for Linux, self-hosted, and web use, and its repository identifies a GPL-3.0 license. The Personal plan is free, billed forever, for up to 10 apps. Lite costs $10 a month, and a seven-day trial is listed.
