What We Detect

  • Security — HSTS, CSP, security header grade
  • Programming Language — PHP, Python, Node.js, ASP.NET

How It Works

We send an HTTP request to the target URL and analyze the response headers. Headers like X-Powered-By, Server, CF-Ray, X-Vercel-Id, and cache headers reveal the technology stack without needing to execute JavaScript.

We also check DNS records (NS, MX, TXT) to identify DNS providers, email services, and domain verification records for popular SaaS tools.
