SafeLine
SafeLine is a self-hosted web application firewall and reverse proxy designed to protect web apps from attacks and exploits.
What SafeLine is
SafeLine is a self-hosted web application firewall and reverse proxy designed to protect web apps from attacks and exploits. The maker describes it as an Nginx-based intermediary that blocks malicious HTTP traffic between applications and the internet. Listed protections include SQL injection, XSS, code injection, XXE, SSRF and path traversal. Anti-bot challenges are intended to let human users through while blocking crawlers and bots, and rate limiting addresses DoS attacks, brute-force attempts, traffic surges and other abuse. Dynamic protection encrypts server HTML and JavaScript 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. The project requires Docker and Docker Compose V2 on the host. SafeLine is available under GPL-3.0. Its Personal plan is free, billed forever, for up to 10 apps. Lite costs $10 a month; Pro costs $100 a month. Ultimate pricing is custom and billed annually. A seven-day trial is listed.
