FAQ

What does it return? One row per website: a flat technologies list (with versions when the site reveals them), the same technologies grouped in categories, a technologyDetails list with name, category and version, plus the HTTP status, final URL, page title and Server header.

How does it detect technologies? It loads the URL you give once, without a browser, and matches the HTML, response headers, cookies and meta tags against 130+ known signatures. It does not crawl other pages, so tools that only load after JavaScript runs may be missed.

How much does it cost? $0.001 per website analysed ($1 per 1,000). Websites that cannot be reached are free. A site that answers, even with an error page, counts as analysed.

How many websites can I check per run? Up to 50,000 websites per run, with or without https://.

Do I need an API key? No. It reads public pages only; private and internal addresses are blocked.

Can I combine it with other Actors? Yes. Run the same list through Website Contact Extractor to add e-mails and phones, or schedule it in Apify to track when sites change their stack.

• No detection is perfect: treat results as strong hints.
