Identify 2,000+ technologies with version detection.

Tech Stack Detection

Knowing what technologies a website uses is essential for competitive analysis, security auditing, and migration planning. EchoBat's Fingerprint engine identifies over 2,000 technologies by analyzing HTTP headers, meta tags, JavaScript globals, HTML patterns, cookies, and DNS records. Unlike browser extensions that only check the current page, EchoBat fingerprints across your entire site and aggregates findings by category.

How It Works

EchoBat's Fingerprint engine runs detection patterns against every response during the crawl. Signatures check HTTP headers (Server, X-Powered-By), HTML meta tags, inline JavaScript globals, cookie names, DNS records, and URL patterns. Each detection includes a confidence score (high/medium/low) with the specific evidence that triggered it. Results are grouped by category and technology, with version information extracted where possible.

Why It Matters

  • Comprehensive 2,000+ technology signature database
  • Exact version detection with evidence trail showing where each was found
  • EOL/outdated technology alerts for security risk assessment
  • Auto-categorized results: frontend, backend, hosting, analytics, security
