Website Tech Stack Detector – CMS, Frameworks, Analytics

Website Tech Stack Detector finds out what technology a website uses, in bulk. For each URL it fetches the page once and matches the HTML and HTTP headers against 115 technology signatures: CMS (WordPress, Shopify, Wix, Webflow…), ecommerce platforms, JavaScript frameworks (React, Next.js, Vue, Angular…), analytics and tag managers, advertising pixels, live chat, marketing automation, CDN, hosting, web servers and backend frameworks.

A Wappalyzer / BuiltWith-style lookup without a browser extension or a subscription: one row per site with the full technology list, technologies grouped by category, and quick cms, ecommerce and analytics columns.

How much does it cost?

This Actor uses pay-per-event pricing. You pay only for results, not for servers or subscriptions:

• $0.002 per URL analyzed, which is $2.00 per 1,000 websites
• plus Apify's standard Actor start event of $0.00005 per run (per GB of memory; the default 512 MB memory = one event)

You process	You pay (approx.)
100 websites	$0.20
1,000 websites	$2.00
10,000 websites	$20.00

Apify's free plan includes monthly platform credit, which is enough to try this Actor at no cost.

Run it via API, schedule or AI agents

Run from your own code with the Apify API, JavaScript or Python client, schedule it in Apify Console, connect it to Make, Zapier, n8n or Google Sheets, or let an AI agent call it through the Apify MCP server (https://mcp.apify.com).

curl -X POST "https://api.apify.com/v2/acts/quillbit-tools~tech-stack-detector/run-sync-get-dataset-items?token=YOUR_APIFY_TOKEN" \

FAQ

Which technologies are detected? CMS (WordPress, Drupal, Joomla, Wix, Squarespace, Webflow, Ghost, HubSpot CMS, Framer, Contentful, Sanity, Blogger, Weebly), ecommerce (Shopify, WooCommerce, Magento, BigCommerce, PrestaShop, Ecwid), JS frameworks (React, Next.js, Vue.js, Nuxt, Angular, Svelte, SvelteKit, Remix, Astro, Gatsby, Ember), analytics (Google Analytics, Hotjar, Clarity, Plausible, Matomo, Segment, Mixpanel, Amplitude, Heap, PostHog…), pixels, live chat, CDN, hosting, web servers and backend frameworks — 115 signatures in total.

How accurate is it? It reports a technology only when its fingerprint (script URL, meta generator, cookie or header) is present in the homepage HTML or headers. Technologies loaded only after JavaScript runs, or only on inner pages, can be missed. Run it on a specific inner URL if needed.

Does it use a browser? No. One plain HTTP request per URL, which is why it costs $2 per 1,000 sites.

What am I charged for? One url-analyzed event per unique URL, including sites that fail (DNS error, timeout).

Can I filter for one technology? Yes. Filter the dataset on technologies or ecommerce / cms in Excel, Google Sheets or via the API.
