Tech Stack Detector | $3/1K | BuiltWith Alternative

What does Website Technology Detector do?

This Actor finds out which technologies a website is built with. Give it a list of domains and get one row per website with the detected:

• CMS and website builder: WordPress, TYPO3, Joomla, Drupal, Contao, Wix, Squarespace, Webflow, Jimdo, IONOS MyWebsite, Ghost, HubSpot CMS and more
• Shop system: Shopify, WooCommerce, Shopware, Magento, PrestaShop, JTL-Shop, Gambio, OXID, BigCommerce, Plentymarkets and more
• Analytics and advertising: Google Analytics 4, Google Tag Manager, Matomo, Plausible, etracker, Hotjar, Microsoft Clarity, Meta Pixel, LinkedIn Insight Tag, TikTok Pixel, Google Ads
• Cookie consent tools: Cookiebot, Usercentrics, OneTrust, Borlabs Cookie, Complianz, CookieYes, Real Cookie Banner, consentmanager, CCM19
• CDN, hosting and web server: Cloudflare, Fastly, Akamai, CloudFront, Vercel, Netlify, nginx, Apache, LiteSpeed, IIS
• Frameworks, page builders, chat, CRM, newsletter, payment, fonts, maps, captchas and more

150+ technologies in total, with version numbers where the website reveals them and the evidence for every detection. No proxies and no browser, so runs are fast and cheap. A lightweight alternative to BuiltWith and Wappalyzer lookups.

Why use this tech stack checker?

• Sales and lead generation: filter a lead list by CMS or shop system, e.g. find all Shopware or old Joomla shops for your offer
• Web agencies: spot websites on outdated systems or without a consent tool, and prepare relaunch pitches
• Market research: measure how common a technology is in your industry or region
• Competitor analysis: see which analytics, ad pixels and marketing tools competitors use
• Bulk lookups: hundreds of domains in one run, export to CSV or Excel
• Pay per website: websites that can't be loaded are free

How to check which technologies a website uses

1. Click Try for free.
2. Paste your domains into Websites, one per line (example.com is enough).
3. Click Start.
4. Open the Overview table, or download everything as JSON, CSV or Excel.

How much does it cost?

This Actor uses pay per event: a fixed price per analyzed website, and platform usage is included. It costs $0.003 per website, so 1,000 websites cost $3. The Pricing tab always shows the binding price. Websites that return an error or can't be reached are not charged.

Use it with AI agents (MCP)

This Actor works as a tool for Claude, ChatGPT, Cursor and other AI assistants through the Apify MCP server. Add this server URL to your MCP client:

https://mcp.apify.com?tools=veedel_digital/tech-stack

Then ask in plain language, for example: "Check which CMS and shop system these 50 websites use and list all Shopify stores."

The assistant fills in the input, runs the Actor and works with the results. You pay the same price per result as in Apify Console.

FAQ

How accurate is the detection?

The Actor analyzes the start page of each website: its HTTP headers, cookies, meta tags, scripts, stylesheets and HTML. Every result comes with the evidence it is based on. Technologies that leave no trace in the delivered HTML (for example a backend database or tools that only load after cookie consent or on subpages) can't be detected. Treat the result as a strong indication, not a guarantee.

Why is a website missing technologies I know it uses?

Some tools are only loaded after the visitor accepts cookies, only on certain subpages, or are injected by JavaScript in the browser. Websites behind strict bot protection may also return a reduced page.

Can I request a technology?

Yes, please open an issue in the Issues tab with the technology name and an example website.

Something does not work

Please open an issue in the Issues tab with the website and the run ID. You can also start the Actor programmatically from the API tab.
