Company Tech-Stack Detector — Website Technology Lookup

What is this site built with? Point this Actor at any list of websites and get back the technologies each one runs — CMS, ecommerce platform, analytics, marketing/CRM, JS framework, hosting/CDN, chat widget and payment provider — read straight from the public HTML and HTTP headers. No browser, no proxies, no login.

Per website you get:

• 🧱 CMS (WordPress, Webflow, Shopify, Wix, Squarespace, Drupal, Ghost, Tilda, Framer…)
• 🛒 Ecommerce platform (Shopify, WooCommerce, Magento, BigCommerce, Salesforce Commerce, PrestaShop)
• 📊 Analytics & tags (GA4, GTM, Meta Pixel, Hotjar, Segment, Amplitude, Mixpanel, Clarity, Plausible)
• 📣 Marketing / CRM (HubSpot, Marketo, Pardot, Klaviyo, Mailchimp)
• 💬 Chat & support (Intercom, Drift, Zendesk, Crisp, Tawk, Calendly)
• ⚛️ Framework (Next.js, Nuxt, Gatsby, Angular, jQuery)
• 💳 Payments (Stripe, PayPal)
• ☁️ Hosting / CDN (Cloudflare, Vercel, Netlify, CloudFront, Fastly, GitHub Pages, nginx, Apache)
• 🎯 Sales signals — plain-English cues like "runs an online store (Shopify)", "invests in marketing automation (HubSpot)", "SaaS with customer-success budget (Intercom)"

Who is this for

• Sales & SDR teams — qualify and segment leads by the tools they already run ("everyone on Shopify + Klaviyo")
• Agencies — find prospects on a platform you specialize in, or audit a client's stack
• Competitive & market research — see what a set of competitors is built on
• Recruiters & analysts — infer a company's engineering choices from the outside

Why it matters

Technographic data behind tools like BuiltWith ($295–995/mo) and Wappalyzer ($250–450/mo, with credits that expire) is derived from the same public source: a page's own HTML and headers. This Actor reads that directly and pays per website checked — no monthly seat, no expiring credits.

Accuracy

Detection is signature-based over the homepage HTML and response headers. Path-based fingerprints (e.g. wp-content/) are matched only when they belong to the site itself — a third-party widget hosted on someone else's WordPress CDN will not misflag the page. Detections are conservative: it reports what it can confirm, not guesses.

FAQ

Does it render JavaScript? No — it reads the served HTML and headers. That's fast, cheap and enough for the fingerprints above. Technologies injected only after heavy client-side rendering may not appear.

Is it accurate? It reports confirmed signatures and avoids the common false positives (e.g. a foreign CDN asset won't mislabel the whole site). It won't detect a technology that leaves no public trace on the homepage.

Is this legal? Yes — it reads publicly served HTML and standard HTTP headers, the same data any browser receives.

Can I filter by technology? Each result lists technologies and byCategory; filter the dataset downstream (e.g. keep only rows where ecommerce == "Shopify").
