Website Tech Stack Detector: 280+ Technologies, Leads & Signals

Point it at websites, or at a Google search like plombier Lyon, and get back everything a sales or agency team needs to qualify and contact the company:

• 🧩 Tech stack: 280+ technologies that matter for small and mid-size businesses. CMS and site builders (WordPress, Wix, Shopify, Jimdo, TYPO3, Webflow…), e-commerce, page builders, analytics, ads pixels, cookie-consent tools, chat, booking, reviews, payment, hosting and CDN. Versions are included where the site exposes them.
• 🏢 Company identity & contacts: legal name, legal form, registry numbers (HRB, SIREN, FN, UID, KvK, BCE, CIF, UK company number), VAT IDs, managing directors, address, emails and phones, read from the site's legal notice (Impressum, mentions légales…).
• 🎯 Sales signals + opportunity score (0–100): the concrete reasons to reach out, such as an outdated WordPress, end-of-life PHP, no HTTPS, a site that isn't mobile-friendly, tracking without cookie consent (GDPR), Google Fonts loaded from Google servers (GDPR), a missing legal notice, a DIY site builder, no analytics, an unmaintained site or a slow server.

✨ Why this Actor

💸 Fair price	The most-used technology lookup on the Store charges $100 / 1,000 sites for technologies alone. Here you get technologies + company identity + contacts + sales signals for $20 / 1,000.
🎯 Built for prospecting	Filter with onlyWithTechnologies: ["Wix"] and minOpportunityScore: 40 to get "companies on Wix with at least two issues, with their manager's name and email" in one run.
🔎 From keywords to leads	Type Tischlerei München or dentist Leeds. Directories and marketplaces (Yelp, Gelbe Seiten, Pages Jaunes, Yoojo…) are skipped, so you get real company websites.
📅 Always current	"Outdated WordPress" and "end-of-life PHP" are computed on every run from WordPress.org and official PHP end-of-life dates, not from a stale list.
🇪🇺 Europe-aware	GDPR signals (consent tool, Google Fonts), and legal-notice parsing in German, French, English, Dutch, Italian and Spanish.
🧾 Evidence included	Every detected technology comes with where it was seen (meta tag, header, cookie, asset, HTML). Detection reads the site's code, never its visible text: an agency writing "we build Shopify stores" is not reported as a Shopify store.

🎯 Use cases

• Web and marketing agencies: find local businesses with an outdated or DIY website, no analytics or GDPR issues, and contact the manager with a concrete argument.
• SaaS and tech sales: build lists of companies using (or not using) a technology, for example Shopify stores with no reviews app, or restaurants with no online booking.
• Market research: technology market share in a sector or city.
• Compliance and security consultants: spot EOL PHP, expired or expiring SSL certificates and missing legal notices.

❓ FAQ

• Why could a website be reported as unreachable when it works in my browser? Many small European websites block foreign servers. The Actor automatically retries those through a residential connection in the website's country; only websites that are really down, parked or not HTML stay unreachable (and are free).
• Is the "slow server" signal reliable? Response time (time to first byte) is measured on a separate thread so the analysis itself never skews it, and it is not reported when the site had to be reached through a proxy.
• What if I set a maximum cost or a short timeout? The Actor stops cleanly before either limit: every website you are charged for is delivered, nothing is charged for work that could not finish, and the run ends as Succeeded with a message telling you how many websites are left.
• How does detection work? It uses EuroScrape's own curated signature database, matched on HTML, scripts, meta tags, HTTP headers and cookies. There's no browser, so it's fast and cheap. Technologies injected later through Google Tag Manager can't always be seen.
• Is it legal? It only reads public pages, the same way a browser does. Contact details come from legal notices that companies must publish by law. Use personal data (manager names) in line with the GDPR.
