Website Tech Stack Detector - CMS, Analytics & 290+ Techs

Website Tech Stack Detector: CMS, Analytics, CDN and 290+ Technologies

Find out what any website is built with. Give this tech stack detector a list of domains and get, for each site, the CMS, ecommerce platform, JavaScript framework, analytics and ad pixels, chat and email-marketing tools, payment providers, CDN, hosting and web server, with the evidence behind every finding. A fast, low-cost alternative to manual Wappalyzer or BuiltWith lookups for whole lists of websites.

What can this technology detector find?

Over 290 technologies in more than 40 categories, including:

• CMS and site builders: WordPress, Shopify, Wix, Squarespace, Webflow, Drupal, Joomla, Ghost, HubSpot CMS, BigCommerce, Magento, WooCommerce
• Frameworks: React, Next.js, Vue, Nuxt, Angular, Svelte, Gatsby, Astro
• Analytics and ads: Google Analytics 4, Google Tag Manager, Meta Pixel, TikTok Pixel, LinkedIn Insight, Hotjar, Segment, Mixpanel, Plausible, Matomo, Microsoft Clarity
• Marketing and chat: HubSpot, Intercom, Drift, Zendesk, Crisp, Tawk.to, Klaviyo, Mailchimp
• Payments, CDN and hosting: Stripe, PayPal, Cloudflare, Fastly, Akamai, Amazon CloudFront, Vercel, Netlify
• Plus fonts, cookie-consent tools, review widgets, search, A/B testing, error tracking and security services.

Each finding has a confidence (high for headers, cookies, meta tags and script URLs; medium for HTML patterns) and its evidence, so you can trust or check every result.

What data do you get?

Field	Description
url, finalUrl, domain	What you entered and where it ended up after redirects
status, statusCode	ok, http_error or blocked, and the HTTP code
title, description, language	Basic page info
technologies	List of {name, category, confidence, evidence}
categories	Category to technology names
cms, ecommerce, frameworks, analytics, cdn, hosting	Quick columns for filtering
server, redirects, responseTimeMs, htmlBytes, technologyCount	Technical details

Who uses it?

• Sales and business-development teams qualifying leads by the tools a prospect uses ("Shopify stores using Klaviyo", "WordPress sites without analytics").
• Agencies and freelancers preparing audits and pitches.
• Software companies sizing a market or tracking competitors' adoption.
• Researchers and investors studying technology trends across lists of companies.

Use it via API, Make, Zapier, n8n or an AI agent

Apify API. Start a run and get the results back in one HTTP request (replace YOUR_API_TOKEN with the token from Apify Console > Settings > Integrations):

curl -X POST "https://api.apify.com/v2/acts/plotpointtech~website-technology-detector/run-sync-get-dataset-items?token=YOUR_API_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"urls": ["https://wordpress.org", "https://nextjs.org", "https://www.nalgene.com", "allbirds.com"], "timeoutSecs": 25}'

For longer jobs, start the run asynchronously and read the dataset when it finishes. Official apify-client libraries exist for Python and JavaScript; the API tab on this page has ready-made code.

No-code automation. Connect the tool to Make, Zapier, n8n, Google Sheets, Slack, Airtable or any webhook with Apify integrations, and use Schedules in Apify Console to run it hourly, daily or weekly.

AI agents (MCP). Give Claude, ChatGPT, Cursor, VS Code or any MCP-compatible agent direct access to this tool through the hosted Apify MCP server. Add this server URL to your client:

https://mcp.apify.com?tools=plotpointtech/website-technology-detector

The agent can then call the tool with the same input fields shown above and read the results.

FAQ

Is it legal to detect a website's technologies? Yes. The tool requests each public home page once, the way a browser does, and reads what the server openly sends. It does not log in or get around bot checks.

How does it compare with Wappalyzer or BuiltWith? It uses the same kind of signals (headers, cookies, meta tags, script URLs and HTML patterns) on the live home page, with evidence for each match. It does not keep historical data or check every inner page.

Why are some tools missing? Only the home page is checked. Tools loaded later by a tag manager, only on inner pages, or only after cookie consent may not be visible.

What does "blocked" mean? The site answered with a bot check (for example a Cloudflare challenge). CDN and security headers are still reported; page-level technologies are not.

How many websites can I check at once? Thousands per run. Sites are checked 10 at a time by default.
