I built a free cybersecurity scanner that gives any website a security score — here's how

I spent the last few weeks building SecureCheck AI — a free web-based cybersecurity intelligence platform for developers.

Here is what it does:

Paste any website URL and get a security score from 0 to 100
It checks real HTTP headers — CSP, X-Frame-Options, HTTPS redirects and more
It tells you exactly what is missing and how to fix it
It detects the tech stack of any website without touching their code
It has a full domain intelligence module — WHOIS, DNS, SSL certificate check
The AI assistant (powered by Groq Llama 3.3) answers security questions and analyzes code

How I know it works

I ran it on my own site and got 75/100. The report said I was missing a Content-Security-Policy header. I added 10 lines to my vercel.json. Ran it again — 100/100. That is exactly what this tool is built for.

What makes it different

Most security scanners are paid, complicated, or built for enterprise teams. This one is free, runs in the browser, and gives developers plain English explanations with exact fix recommendations.

Try it here:
https://securecheck-ui.vercel.app

Modules available right now:

Security Scanner
Technology Intelligence
Domain Intelligence
API Intelligence
Payment Lab
AI Security Assistant
Community Hub

Built with React, Tailwind, Node.js on Render, and Groq AI.

Would love feedback from the security community — what other checks should I add?
