SafeLine is a self‑hosted Web Application Firewall and reverse‑proxy written in Go. It protects web services by filtering malicious HTTP traffic using machine‑learning‑driven detection and configurable rules.

Use cases

• Block SQL injection, XSS and other web‑app attacks before they reach my server
• Mitigate HTTP flood and DDoS attacks on my public website
• Add CAPTCHA‑based bot protection for login and form endpoints
• Deploy a reverse‑proxy that enforces security policies for multiple microservices
• Implement API gateway security with rate‑limiting and request validation
• Protect legacy applications that cannot be modified with a front‑line WAF

When to choose

• You need a self‑hosted, open‑source WAF that can run on‑prem or in your own cloud
• You want ML‑enhanced threat detection with low false‑positive rates
• You prefer a single‑binary Go solution that is easy to deploy via Docker or a binary
• You require built‑in bot protection, CAPTCHA, and HTTP‑flood mitigation

When to avoid

• You prefer a fully managed SaaS WAF with zero operational overhead
• Your environment only supports proprietary platforms not covered by Go binaries
• You need deep integration with a specific commercial WAF ecosystem
• You have extremely low traffic and the overhead of a reverse‑proxy is unnecessary
