If you run a website, you’re already under attack.
SQL injections, XSS payloads, cookie tampering, and bot crawlers hit your endpoints daily. Most of them never show up in your logs.
The usual options?
- Cloud WAFs: powerful, but expensive.
- Open-source tools: free, but noisy and hard to manage.
- DIY rules: time sink, never-ending updates.
That’s why SafeLine WAF has been getting attention from developers in 2025.
What Is SafeLine?
SafeLine is an open-source web application firewall (WAF) built by Chaitin Tech and trusted by engineers at major Asian tech companies. It’s designed to stop the common attacks that break apps every day—SQLi, XSS, CSRF, file inclusion—right out of the box.
Unlike most WAFs, it doesn’t just rely on static regex rules. SafeLine uses semantic analysis of HTTP traffic to parse requests like a browser does. Result: attacks are detected even if payloads are obfuscated, while false positives stay as low as 0.01%.
Why Developers Recommend It
- Open Source & Free: The core version is free forever.
- Smarter Detection: Blocks SQLi and XSS payloads that bypass regex-based filters.
- Quick Deploy: Runs as a reverse proxy—Docker/K8s supported. One command, up in minutes.
- Community Backing: Over 400,000 deployments worldwide.
Quick Start
You can spin up SafeLine on a CentOS server in under 5 minutes. Docker users? Even faster.

Why This Matters in 2025
AI-powered bots and automated scanners are getting smarter every day. If you’re still running without a WAF—or relying on outdated rules—you’re leaving the door wide open.
SafeLine gives you enterprise-grade protection without the enterprise headache.
Stay safe, stay open source.
