🕳️ Tech Stack Detector: Wappalyzer & BuiltWith Alternative

Find out what any website is built with, in bulk. CMS, ecommerce platform, analytics, ad pixels, CDN, hosting, frameworks, libraries and versions, detected from 7,600+ technology fingerprints. Every result also includes tracking IDs (GA4, GTM, Meta Pixel...), social profiles, email provider and SSL issuer.

By DataMole. We dig the data you need.

Tech Stack Detector scans websites the way Wappalyzer and BuiltWith do and returns clean, structured JSON. Paste domains, full URLs or even email addresses, and the Actor removes duplicates, scans them in parallel and groups every detected technology by category. Choose Fast mode for large lists, or Deep mode to render each page in a real browser and catch JavaScript-only tools. In our tests Deep mode usually finds about twice as many technologies, including versions.

✨ Why this one

• ✅ 7,600+ fingerprints, continuously updated from the community-maintained open-source database.
• ✅ Two modes: fast and cheap for big lists, or deep for maximum coverage.
• ✅ Sales-ready extras: tracking IDs, social profiles and email provider in the same row.
• ✅ Versions and confidence scores for every technology.
• ✅ Bulk friendly: accepts messy input (URLs, emails), removes duplicates, retries with www., and clearly reports sites that don't exist.
• ✅ No API key, no login, no proxy needed for most websites.

❓ FAQ

Fast or Deep? Use Fast for thousands of domains or when you only need the CMS, ecommerce platform and infrastructure. Use Deep when you need marketing, analytics and JavaScript framework details. Deep mode finds roughly twice as many technologies but is slower.

How accurate is it? Detection uses the same fingerprinting approach as Wappalyzer. Each technology comes with a confidence score and the signals that triggered it (detectedVia), so you can filter with confidence.

Why did a website fail? Some domains have no website, block bots, or time out. They appear as rows with a clear error message and are not counted as results.

Can I filter to one category? Yes. Use categories, for example ["Ecommerce"] to build a list of online stores and their platforms.
