Website Tech Stack Detector: Wappalyzer Alternative

For sales teams, agencies and developers who need to know what a list of websites is built on: one row per URL with its CMS, ecommerce platform, framework, analytics, hosting, payment and chat tools.

What you get

• cms, ecommerce and jsFrameworks: for example WordPress, Shopify or Next.js
• analytics, payment and liveChat: for example Google Analytics, Stripe or Intercom
• cdnHosting (for example Cloudflare or Vercel), plus the raw server, poweredBy and generator values the site reports, which can include the exact WordPress version
• status and error on every row: "ok", or "error" with the reason a site couldn't be checked, so you always know which URLs failed and why

Example output

Real output from a run on Apify (2026-10-19):

{
  "rowType": "site",
  "url": "https://www.brooklinen.com/",
  "finalUrl": "https://www.brooklinen.com/",
  "status": "ok",
  "error": null,
  "cms": [],
  "ecommerce": ["Shopify"],
  "jsFrameworks": [],
  "analytics": ["Google Analytics"],
  "cdnHosting": ["Cloudflare"],
  "payment": [],
  "liveChat": [],
  "server": "cloudflare",
  "poweredBy": null,
  "generator": null,
  "analyzedAt": "2026-10-19T03:40:53.782Z"
}

In the same run, techcrunch.com came back as WordPress on Cloudflare with "generator": "wordpress 6.9.10", and notion.com as Next.js on Vercel and Cloudflare. A domain that doesn't exist came back like this, and wasn't charged:

{
  "rowType": "error",
  "url": "https://this-domain-does-not-exist-xyz123.com/",
  "finalUrl": null,
  "status": "error",
  "error": "The domain doesn't resolve (DNS lookup failed)."
}

(The empty technology fields are left out of this second example.)

What it costs

$0.007 per site analyzed on the Free plan, and less on paid Apify plans ($0.0065 Bronze, $0.006 Silver, $0.0055 Gold and above). Nothing else is billed.

• 100 sites checked = $0.70
• 1,000 sites checked = $7.00

Only rows with "status": "ok" are charged. A URL that can't be checked gets an "error" row with the reason and costs nothing. A URL listed twice is checked, and charged, once.

Use cases

• Before a sales call, find which leads run Shopify, WordPress or HubSpot.
• Before quoting a redesign or migration, check a prospect's CMS and hosting.
• Count how many sites in a list use a given analytics, payment or chat tool.

Input

Field	Type	Description
startUrls	array of URLs	The websites to check. Only the homepage of each is checked, not the whole site. If you leave it empty, it checks brooklinen.com, techcrunch.com and notion.com.

{
  "startUrls": [
    { "url": "https://www.brooklinen.com" },
    { "url": "https://techcrunch.com" },
    { "url": "https://www.notion.com" }
  ]
}

• Tech Stack Lead Finder: find sites that use a technology, for example Shopify stores without Klaviyo, across 120+ technologies
• Website Email & Phone Extractor: get the contact details of the sites you want to pitch

Notes

• What it recognises: 36 technologies.
  • CMS: WordPress, Drupal, Joomla, Wix, Squarespace, Webflow, Ghost, HubSpot CMS
  • Ecommerce: Shopify, WooCommerce, Magento, BigCommerce
  • Frameworks: Next.js, Nuxt, React, Vue.js, Angular, jQuery
  • Analytics: Google Analytics, Google Tag Manager, Meta Pixel, Hotjar, Segment, Mixpanel, HubSpot Analytics
  • Hosting and CDN: Cloudflare, Vercel, Netlify, AWS CloudFront, Fastly, GitHub Pages
  • Payment: Stripe, PayPal
  • Chat: Intercom, Drift, Zendesk Chat
• How it checks: it reads the homepage's HTML and response headers from one plain HTTP request, with no browser. Tools that load later through JavaScript or a tag manager can be missed. For example, stripe.com shows only Next.js and an nginx server.
• When a site blocks it: sites that refuse automated requests come back as "error" with the HTTP status (for example 403), uncharged.
• Freshness: every run checks the live site. Nothing is cached.
• Feedback and support: open an issue in the Issues tab on this page. Missing technologies you'd like detected are welcome there too.
