Tech Stack Detector: CMS, Frameworks, Analytics & Hosting

Find out what any website is built with, in bulk. Paste domains and get, for each site, the detected CMS / ecommerce platform, JavaScript framework, analytics & ad pixels, tag manager, CDN, hosting, web server, live chat, payments, cookie consent, A/B testing and more, with the evidence behind every detection. A lightweight Wappalyzer / BuiltWith alternative.

Use cases

• Lead generation & sales prospecting: find Shopify stores, WordPress sites or HubSpot users in a list of domains and qualify leads by stack.
• Competitor research: see which analytics, A/B testing and chat tools competitors use.
• Agencies: audit client/prospect sites before a pitch (outdated jQuery, no analytics, no CDN…).
• Market research: measure technology adoption across thousands of domains.

Notes

• Analyzes the public homepage HTML and HTTP response headers (no browser), so it's fast and cheap. Technologies injected only at runtime by JavaScript may be missed.
• No login, no personal data collected.
