(real output of a test run on 2026-11-04, shortened to 5 of the columns; the output's url column holds the full URL)

One flat row per site: CMS, framework, hosting/CDN, analytics, tag managers, ad pixels and the GTM / GA4 / Ads / Meta Pixel IDs in the page source — ready for Excel or Google Sheets.

Try it: press Start with the prefilled example (example.com and python.org). You get the python.org and example.com rows above in about 5 seconds, charged as 2 analysed sites (less than half a cent). Clear the URL list and press Start to get the same 2 rows as a free demo (not charged).

Price: from $1.40 per 1,000 analysed sites on Apify's paid plans (the price shown on this page); $2.00 per 1,000 on the free plan. Failed, blocked or error pages are not charged.

• Who it's for: agencies, sales teams building prospect lists by technology, market researchers, developers.
• Bulk: up to 1,000 URLs per run; one request per site, no proxies or browser needed.
• Tag IDs included: GTM, GA4, Google Ads and Meta Pixel IDs found in the page source.

Use cases

• Market and competitor research: which sites in a list run Shopify, WordPress, Webflow, Next.js and so on
• Prospect lists by technology: filter a CSV of domains by platform, payment provider or chat tool
• Tag inventory: collect the GTM container IDs, GA4 measurement IDs, Ads IDs and pixel IDs that appear in the page source of many sites at once
• Migration and handover notes: record what a site currently uses (server, CDN, CMS version when the page states it)

What you get (one row per URL)

Column	Content
url, finalUrl, status	the address you gave, where it ended after redirects, the HTTP status
technologyNames	comma-separated list, for example WordPress, Cloudflare, Google Tag Manager
categories	comma-separated categories, for example CMS, CDN, Tag manager
gtmIds, ga4Ids, adsIds, metaPixelIds	public IDs found in the page source
otherTrackingTags	other tag IDs, as TikTok Pixel: XXXX, Hotjar: 123456
technologies	JSON array: name, category, version (when the page states it) and evidence
trackingTags	JSON array of {name, id}
checkedAt, error	time of the request and the error code if the page could not be read

evidence says exactly where each technology was seen, for example script src contains googletagmanager.com/gtm.js?id=GTM-ABC1234, header server: nginx/1.24.0, meta generator: WordPress 6.4.2 or cookie name _fbp.

Example

Input:

{ "urls": ["https://example.com", "shop.example.org", "https://www.python.org"], "includeTracking": true }

Output row (shortened, illustrative):

{
  "url": "https://www.example.org", "finalUrl": "https://www.example.org/", "status": 200,
  "technologyNames": "Cloudflare, Google Tag Manager, jQuery",
  "categories": "CDN, JavaScript library, Tag manager",
  "gtmIds": "GTM-XXXXXXX", "ga4Ids": "", "adsIds": "", "metaPixelIds": "", "otherTrackingTags": "",
  "technologies": [{"name": "Google Tag Manager", "category": "Tag manager", "version": null,
                    "evidence": "script src contains googletagmanager.com/gtm.js?id=GTM-XXXXXXX"}],
  "checkedAt": "2026-10-20T09:00:00+00:00", "error": null
}

Addresses without https:// are accepted and get https:// added.

What it detects (230+ technologies, rules written for this Actor)

• CMS, site builders and ecommerce: WordPress, Shopify, Wix, Squarespace, Webflow, Drupal, Joomla, Ghost, HubSpot CMS, Magento, WooCommerce, BigCommerce, PrestaShop, TYPO3, Framer, static site generators and headless CMS
• JavaScript and CSS: React, Next.js, Vue.js, Nuxt, Angular, Svelte, jQuery, Alpine.js, htmx, Bootstrap, Tailwind CSS and more
• Servers, CDN and hosting: nginx, Apache, Cloudflare, Fastly, Akamai, Amazon CloudFront, Vercel, Netlify, Google Cloud, Azure and more

• Chat, support, payments, fonts, maps, video: Intercom, Zendesk, Drift, HubSpot, Stripe, PayPal, Klarna, Google Fonts, Adobe Fonts, Google Maps and more

Set includeTracking to false to leave analytics, tag managers, ad pixels and session-replay tools (and the ID columns) out of the result.

How it works

• One request per URL (redirects followed, up to 5). It reads the response headers, the names of cookies the server sets (never their values), the HTML (first 2 MB) and the src of script tags. External JavaScript files are not downloaded.
• Because only the first page is read, technologies that a site loads after the page is rendered in a browser are not seen. Results reflect what a plain HTTP client receives.
• Polite by design: 8 sites in parallel, at most 2 connections per host, 20 second timeout, an honest User-Agent.
• Internal and private addresses (localhost, private ranges, 169.254.169.254) are never contacted, including redirect targets; the row gets blocked_private_address.
• Detection only: the output lists what is present and where it was seen.

Price

Event	Free plan	Paid plans (Store discount tiers Bronze / Silver / Gold)
Analysed site (one URL fetched and analysed, HTTP status below 400)	$2.00 per 1,000	$1.80 / $1.60 / $1.40 per 1,000

The price on this page ("from $1.40") is the Gold tier price. 100 sites cost 20 cents on the free plan. On the Apify Free plan, the $5 of monthly platform credit covers about 2,500 sites a month — enough to try it on real data.

Not charged: timeouts, DNS failures, redirect loops, HTTP 4xx/5xx pages, blocked and invalid URLs, and the empty-input demo. A row is charged only after it has been written to the dataset. If you set a maximum cost per run, the run stops when the limit is reached.

Notes

Only request addresses you are allowed to access. Some sites block automated requests; those rows show the HTTP status or error. Versions are reported only when the page, header or script address states them.

If this Actor saved you time, a rating on the Store helps others find it.
