Check What CMS & Tech Stack Websites Use, in Bulk

What it does: tells you what each website in a list is built with, by Print & Plan UK. You give it: website URLs or bare domains. You get: one row per site listing its CMS or site builder, ecommerce platform (Shopify, WooCommerce and others), analytics, tag manager, ad pixels, cookie tool, live chat, payments, framework, server and CDN, each with a confidence score and the evidence that triggered it. Cost per run: $0.002 per site analysed, so 1,000 sites cost $2; blocked, failed or robots-disallowed sites are free. Example inputs: https://www.allbirds.com, https://wordpress.org/news/, gov.uk.

Good for sales prospecting ("every Shopify store in my list that has no live chat"), agency audits, competitor research and market sizing.

Highlights

• 185+ technologies in 30+ categories, including Shopify, WooCommerce, Magento, WordPress, Webflow, Wix, Next.js, Nuxt, GA4, GTM, Meta Pixel, HubSpot, Klaviyo, Intercom, OneTrust, Stripe, Klarna, Cloudflare, Vercel and Fastly.
• Evidence for every detection, e.g. header powered-by: Shopify, meta generator: WordPress 6.6. Easy to trust and easy to filter.
• Lightweight and polite: one page request per site plus robots.txt (honoured per RFC 9309). No headless browser, no proxies, no logins.
• Versions where the site exposes them (WordPress, Drupal, nginx, PHP, jQuery and others).
• $2 per 1,000 sites. Sites that block bots, fail or disallow crawling are free.

Input example

{
  "urls": ["https://www.allbirds.com", "https://wordpress.org/news/", "https://vercel.com", "gov.uk"],
  "includeEvidence": true,
  "maxConcurrency": 10
}

Output example (trimmed)

{
  "url": "https://www.allbirds.com/",
  "httpStatus": 200,
  "title": "Allbirds: Comfortable, Sustainable Shoes & Apparel",
  "technologyCount": 10,
  "technologyNames": ["Cloudflare", "OneTrust", "Shopify", "Swiper", "HTTP/3", "Open Graph", "Content Security Policy", "HSTS", "Microsoft Clarity", "Google Tag Manager"],
  "categories": {"Ecommerce": ["Shopify"], "CDN": ["Cloudflare"], "Cookie consent": ["OneTrust"], "Tag manager": ["Google Tag Manager"], "Session recording": ["Microsoft Clarity"]},
  "technologies": [
    {"name": "Shopify", "category": "Ecommerce", "confidence": 100, "version": null, "evidence": ["header powered-by: Shopify", "html: cdn.shopify.com"]},
    {"name": "Cloudflare", "category": "CDN", "confidence": 100, "version": null, "evidence": ["header server: cloudflare", "header cf-ray: …"]}
  ]
}

Confidence: 100 means a header, meta tag or cookie name matched (or two independent signals did). 75 means a single script or HTML signature. 50 means implied by another technology (e.g. WooCommerce implies WordPress) or a heuristic.

Pricing (pay per event)

Event	Price
Site analysed	$0.002 (= $2 per 1,000 sites)

Not charged: invalid URLs, sites disallowed by robots.txt, HTTP 4xx/5xx responses (partial header-level detections are still returned) and network errors.

FAQ

Why didn't it detect X? Only the first HTML response is analysed and JavaScript is not executed, so tools injected later by a tag manager may not appear. That keeps the Actor fast and cheap. Request a technology through the Issues tab.

Some sites return 403? Some sites block all automated traffic. We respect that and don't use proxies or browser disguises to get around it, and those sites cost you nothing.

Are cookies stored? Only cookie names are used for matching. Values are never read into the output.
