Tech Stack Detector - Website Technology Lookup

Detect the technologies used by a website: frameworks, CMS, analytics, CDN, payments, hosting. The Actor fetches one URL with a single HTTP request and matches it against a set of about 90 Wappalyzer-style technology signatures.

No browser, no API key, no start fee.

How it works

1. Fetches the page via HTTP GET through Apify Proxy (retried up to 3 times on network or HTTP errors)
2. Analyzes 5 signal sources: HTTP headers, HTML patterns, script URLs, meta tags, cookies
3. Matches against a list of about 90 technology signatures
4. Returns deduplicated results grouped by category

Use cases

• Sales prospecting — qualify leads by the tools they already use (e.g. find all Shopify stores running Klaviyo)
• Competitive intelligence — see which technologies other sites in your market use
• Technical review — list the server, CDN and security headers a site exposes
• Due diligence — get a first inventory of a company website's technical footprint
• AI / LLM workflows — feed the structured JSON output into LLM pipelines for automated analysis

Limitations

• Scans one URL per run (the homepage or the URL you give), not the whole site.
• Detection is based on the HTML, HTTP headers, script URLs, meta tags and cookies returned by a single request. JavaScript is not executed, so technologies loaded only client-side (e.g. injected by a tag manager) may be missed.
• Only technologies in the built-in signature list (about 90) can be detected; versions are not reported.
• If the site blocks or rejects the request after the retries, the run fails.
