Tech Stack Detector — Wappalyzer Alternative

Detect the technology stack of any website in seconds. Give this Actor a list of domains and get back structured tech profiles: CMS, JavaScript frameworks, analytics, ecommerce platforms, CDN, hosting, advertising and marketing tools — grouped by category, with versions where identifiable. Pure HTTP: no browser, no proxies, no API key.

Why this Actor

• 104 technology fingerprints — a curated detection database covering the tools that actually matter: WordPress, Shopify, React, Next.js, Vue, Google Analytics, HubSpot, Cloudflare, Stripe, and 90+ more.
• Multiple signal sources — page HTML, response headers, script URLs, meta tags, and cookies are all analyzed, so detection works even when one signal is hidden.
• Versions where identifiable — WordPress 6.4.2, not just "WordPress"; nginx 1.24.0, not just "nginx".
• Confidence scores — every detection is labeled high (authoritative signal like a meta generator tag or response header) or medium (HTML pattern match).
• 20x cheaper than the leading alternative — $0.005 per domain instead of $0.10.

Inputs

• Websites — domains or URLs, one per line (e.g. https://example.com).
• Include versions — try to extract technology versions (default on).
• Request concurrency — parallel analysis (default 5, max 20).

Output

One dataset item per domain:

{
  "domain": "example.com",
  "url": "https://example.com/",
  "statusCode": 200,
  "technologies": [
    {"name": "WordPress", "categories": ["CMS"],
     "version": "6.4.2", "confidence": "high"},
    {"name": "Cloudflare", "categories": ["CDN", "Security"],
     "version": "", "confidence": "high"}
  ],
  "technologyNames": ["WordPress", "Cloudflare"],
  "categories": {
    "CMS": ["WordPress 6.4.2"],
    "CDN": ["Cloudflare"]
  },
  "technologyCount": 2
}

Export to Excel, CSV, JSON, XML, or HTML straight from the Apify dataset.

Pricing

• $0.005 per domain analyzed (pay-per-event detection) — only successfully analyzed domains are billed.
• $0.00005 Actor start per run.

Notes

• Detection is fingerprint-based: sites with heavily obfuscated markup may report fewer technologies.
• Only the homepage is fetched per domain; no crawling, no JavaScript execution.
