Website Technology & Tracking Detector

What does Website Technology & Tracking Detector do?

Paste a list of websites and get back, for each one, the technologies it runs on, grouped into useful buckets:

• CMS and site builders: WordPress, Drupal, Webflow, Wix, Squarespace, Framer, Ghost and more
• E-commerce: Shopify, WooCommerce, BigCommerce, Magento, PrestaShop and others
• Analytics and tag managers: GA4, Tag Manager, Segment, Mixpanel, Amplitude, Hotjar, Clarity and more
• Advertising pixels: Meta, Google Ads, LinkedIn, TikTok, Pinterest, Snap, Microsoft, Reddit, Criteo and more
• Marketing: HubSpot, Marketo, Klaviyo, Mailchimp, ActiveCampaign, SMS and pop-up tools
• Chat and support, payments and BNPL, reviews, scheduling and forms, cookie consent
• Frameworks, hosting, CDN and web server

It also pulls out tracking IDs found on the page: GA4 measurement IDs, GTM containers, Google Ads conversion IDs, AdSense publisher IDs, Meta and TikTok pixel IDs, HubSpot portal IDs and more.

About 140 technologies are covered. The signature list is our own and is updated over time.

Who uses it?

• Sales teams and agencies qualifying leads by stack ("Shopify stores with no email tool", "WordPress sites running Google Ads")
• SaaS companies finding users of a competitor or a complementary tool
• Marketers auditing their own and clients' tracking setup (missing pixels, duplicate tag managers)
• Analysts sizing technology adoption across a domain list
• AI agents that need a fast "what does this site use?" answer

How it works and its limits

• The home page HTML, script URLs, response headers and cookies are matched against our signatures. No browser is used, so it is fast and cheap.
• Tools that load only after a click, a login or a consent banner may not be visible. Results show what the public home page reveals.
• robots.txt is respected by default. No logins, no anti-bot circumvention.
• Product and company names are used only to describe what was detected. This tool is not affiliated with any of them.

FAQ

Can I check inner pages? Enter any URL, not only home pages. Each URL is one check.

How accurate is it? Detection is based on clear fingerprints like script hosts and generator tags, so false positives are rare. Server-side tools that leave no trace in the page can't be seen.
