What it is

SafeLine is a self-hosted web application firewall and reverse proxy that filters traffic between web applications and the internet. Its Nginx-based design is described as blocking malicious HTTP traffic, with protection listed for SQL injection, XSS, code injection, XXE, SSRF and path traversal. Anti-bot challenges aim to distinguish human visitors from crawlers and bots, while 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. Listed 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. The repository identifies the license as GPL-3.0. SafeLine lists Linux, self-hosted and web platforms. Its Personal plan costs nothing, billed forever, for up to 10 apps. Lite is $10 a month, and Pro is $100 a month. Ultimate pricing is custom and billed annually. A seven-day trial is listed.
