3-Minute Setup: The Open Source WAF That’s Taking Over GitHub

Looking for a Web Application Firewall (WAF) that actually works — and doesn't take hours to configure?
Meet SafeLine, a lightweight, open source WAF that’s built for developers, DevOps teams, and security engineers who want real protection without the complexity.

SafeLine is gaining serious traction with 310,000+ installs and 16K+ GitHub stars, thanks to its intelligent detection engine and rapid 3-minute deployment.

Let’s see why it’s quickly becoming a favorite among developers and security professionals.

🔍 What Makes SafeLine Stand Out?

🧠 Intelligent Semantic Analysis Engine

• No rule library needed: SafeLine analyzes HTTP request semantics to detect attack intent, not just patterns.

• Excellent zero-day defense: Intercepts 98% of unknown attacks like SQLi, XSS, and RCE in real-world testing.

• False positives under 0.1%: Learns user behavior to distinguish legit traffic from malicious activity.

🔐 Real-Time Dynamic Protection

• Dynamic Protection: SafeLine encrypts HTML and JavaScript on the fly, generating random code each visit.
  Example:

  • Before: /admin/login is exposed in source.

  • After: paths become /a1b2c3, and change on every refresh.
    Bots and scanners can’t keep up.

• Bot & scanner blocking: Detects and blocks automated tools using fingerprinting, mouse movement, IP reputation, and more.

⚙️ Lightweight & Easy to Deploy

• Quick Docker install: Works on single-core CPU, 1GB RAM — setup takes just minutes.

• Intuitive dashboard: Real-time logs, traffic stats, and attack reports with zero learning curve.

🚀 Get Protected in 3 Minutes

On your Linux server, run:

bash -c "$(curl -fsSLk https://waf-ce.chaitin.cn/release/latest/manager.sh)"

Then access the dashboard at:

https://<your-server-ip>:9443/

First-time login? Reset the admin password with:

docker exec safeline-mgt resetadmin

Output looks like this:

[SafeLine] Initial username: admin  
[SafeLine] Initial password: **********

Once logged in, add your website in the panel — SafeLine immediately starts filtering and monitoring your traffic.

🛡️ Block Attacks and View Logs in Real Time

Hackers and bots trying to attack your site will get a hard stop message — while you get full visibility in the dashboard:

• Attacker IPs

• Payloads used

• Attack types

• Timestamps and frequency

Know exactly who’s trying to break in — and how they failed.

🌐 Highlights

• Core engine is fully open and production-ready

• Works seamlessly with ELK or other monitoring stacks

• Includes essential detection and alerts

Simple, powerful, and open. SafeLine is everything a modern WAF should be.

🧠 Final Thoughts

SafeLine is fast to deploy, easy to use, and extremely effective at keeping bad traffic out.
If you're running a personal site, a SaaS project, or managing cloud services — give it a try.
