Website Tech Stack Detector

What is Website Tech Stack Detector?

Website Tech Stack Detector is an Apify Actor that tells you what any website is built on: CMS, e-commerce platform, analytics, ad pixels, e-mail marketing, chat widget, payment provider, framework, cookie-consent tool, and hosting — one clean row per website, not per page. It runs on plain HTTP, no headless browser, so a few thousand domains is fast and cheap.

What data does Website Tech Stack Detector extract?

Website Tech Stack Detector extracts every signature anchored to something a site can only have if it truly runs it — a vendor CDN hostname, a namespaced variable, a generator tag:

Field	Type	Description
domain	string	Root domain, www. stripped
title / description	string	Homepage title and meta description
generator	string	<meta name="generator"> tag, if present
cms / ecommerce	array	CMS and e-commerce platforms
analytics / advertising	array	Analytics tools and ad pixels
emailMarketing / chat / payments	array	Marketing, chat, payment tools
frameworks / cookieConsent	array	Frameworks and consent tools
cdn / server	array	Hosting and web server
primaryCms / primaryEcommerce	string	Best single guess
isEcommerce	boolean	True if a shop platform was found
trackingIds	object	GA4, GTM, Ads, Meta Pixel, Hotjar, Yandex, TikTok IDs
technologies / technologyCount	array/number	All detections, count
pagesCrawled / scrapedAt	number/string	Pages fetched, timestamp
error	string	Error message if domain could not be crawled (null if successful)

How to use Website Tech Stack Detector

1. Paste your websites into Websites (bare domains or full URLs).
2. Optionally pick Technology categories; empty means everything. Leave Max pages per website at 3.
3. Enable Follow subdomains for sites like shop.example.com, then click Start and download results as JSON, CSV, Excel, or HTML.

Pricing

Website Tech Stack Detector uses pay-per-event pricing: $0.005 per website result ($5 per 1,000), plus a negligible $0.00005 actor-start fee, with platform usage included. HTML-only fetching keeps a 1,000-domain list at 3 pages each to a few cents of compute. Set Maximum cost per run to cap spend.

Website Tech Stack Detector vs. BuiltWith and Wappalyzer subscriptions

BuiltWith and Wappalyzer sell monthly subscriptions with lookup caps. This Actor is pay-per-event, run on demand or on a schedule, results straight into a dataset or your own pipeline via the API — no subscription, no unused seats.

Using Website Tech Stack Detector with AI agents and MCP

Website Tech Stack Detector runs on pay-per-event pricing with limited permissions — the two requirements for an Actor to be callable through the Apify MCP server at mcp.apify.com. An agent passes startUrls and gets one row per domain back, and connects via n8n, Make, Zapier, or LangChain through Apify's integrations.

FAQ

How accurate is it? Every signature is anchored to something a site can only have if it truly runs that technology, not a brand name in page text.

Why did it miss a tool I know is there? Usually Google Tag Manager: tags loaded through GTM are injected at runtime and never appear in HTML, which this Actor reads only — it reports the GTM container, not the tags inside it. Raising maxPagesPerDomain helps for scripts on missed pages.

Does it detect Turkish e-commerce platforms? Yes — Ticimax, IdeaSoft, T-Soft, ikas, Platin Market, iyzico, PayTR, and Shopier.

Is this legal to run? The Actor reads only public HTML and collects no personal data. You're responsible for complying with the sites' terms and applicable law.

How do I control cost? Set Maximum cost per run — narrowing categories and lowering Max pages per website also cut compute.

Can I export as CSV or Excel? Yes, from the Output tab and API.
