Tech Stack Detector — CMS, Ecommerce & Marketing Stack Lookup

Point this Actor at a list of websites and find out exactly what each one runs — CMS, ecommerce platform, analytics, marketing/CRM, chat widget, JS framework, payment provider and hosting/CDN — read straight from the public HTML and HTTP headers. No browser, no proxies, no login, nothing to configure.

What you get

• CMS — WordPress, Webflow, Shopify, Wix, Squarespace, Drupal, Joomla, Ghost, Tilda, Framer.
• Ecommerce platform — Shopify, WooCommerce, Magento, BigCommerce, Salesforce Commerce, PrestaShop.
• Analytics & tags — GA4, Universal Analytics, Google Tag Manager, Meta Pixel, Hotjar, Segment, Mixpanel, Amplitude, Plausible, Microsoft Clarity.
• Marketing / CRM — HubSpot, Marketo, Salesforce Pardot, Mailchimp, Klaviyo.
• Chat & support — Intercom, Drift, Zendesk, Crisp, Tawk.to, Calendly.
• Framework — Next.js, Nuxt, Gatsby, Angular, jQuery.
• Payments — Stripe, PayPal.
• Hosting / CDN — Cloudflare, Vercel, Netlify, AWS CloudFront, Fastly, GitHub Pages, Nginx, Apache.
• Sales signals — plain-English cues such as "runs an online store (Shopify)", "invests in marketing automation (HubSpot)", "SaaS with customer-success budget (Intercom)".
• Runs on Apify: schedule it, monitor it, call it from the API, export to JSON/CSV/Excel or push straight into your own pipeline.

Who is this for

• Sales & SDR teams — qualify and segment leads by the tools they already run
• 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 charges 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, so 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 — a technology that leaves no public trace on the homepage won't show up.

How to run it

1. Click Try for free — no card needed on the free plan.
2. Paste your websites into Websites, one per line.
3. Press Start. Results land in the dataset — read them in the UI, pull them from the API, or have a webhook push them onward.

Pricing

Pay-per-event: $0.005 per run start + $0.005 per result. No monthly seat, no minimum. 100 websites cost about $0.51; 1,000 websites about $5.01.

A website that could not be fingerprinted is still returned, with found: false and the reason — and it is not charged for. You pay for answers, not for attempts.

Input

Field	Required	What it does
websites	yes	Websites to fingerprint. Up to 100 per run.
maxConcurrency	no	How many to check at once, 1–50 (default 10).

{
    "websites": ["shopify.com", "wordpress.org", "vercel.com"],
    "maxConcurrency": 10
}

Output

One row per website. This is a real row from a real run:

{
    "url": "https://wordpress.org/",
    "checkedAt": "2026-07-26T13:28:51.658Z",
    "found": true,
    "httpStatus": 200,
    "technologiesCount": 4,
    "technologies": ["WordPress", "Google Tag Manager", "Nginx", "Google Fonts"],
    "byCategory": {
        "CMS": ["WordPress"],
        "Tag Manager": ["Google Tag Manager"],
        "Hosting/CDN": ["Nginx"],
        "Fonts": ["Google Fonts"]
    },
    "cms": "WordPress",
    "ecommerce": null,
    "hosting": "Nginx",
    "salesSignals": [],
    "summary": "https://wordpress.org/ — WordPress, Nginx. 4 technologies detected."
}

Field	What it means
technologies / technologiesCount	Full flat list and its length
byCategory	Same technologies grouped — CMS, Ecommerce, Analytics, Tag Manager, Marketing/CRM, Chat/Support, Framework, Payments, Hosting/CDN, Fonts
salesSignals	Plain-English cues, empty when the stack has none worth flagging
found	false means fingerprinting failed; the row says why and is not billed

FAQ

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

Is it accurate? It reports confirmed signatures and avoids the common false positive of a foreign CDN asset mislabeling 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? Every result lists technologies and byCategory; filter the dataset downstream, e.g. keep only rows where ecommerce == "Shopify".

Can I call it from an AI agent? Yes — standard Apify Actor, callable from the Apify API, the SDK, or the Apify MCP server.

What this is NOT. It does not render pages, detect technology hidden behind heavy client-side JavaScript, or replace a full technographic database. It reads what the homepage's HTML and headers actually expose.
