How CRFT Lookup Works Its Magic
So, how does CRFT Lookup play tech detective? It’s like a digital forensics expert, analyzing a website’s HTML, JavaScript, response headers, and more. Powered by a database of over 2,500 technology fingerprints, it spins up a headless Chromium instance to scan any URL you throw its way. In seconds, it identifies frameworks, CMS platforms, analytics tools, and—yes—Shopify apps like Klaviyo, Judge.me, or ReCharge.
Enter a Shopify store’s URL, and CRFT Lookup will sniff out the apps leaving public-facing clues in the code. It’s not just about Shopify, though—this tool can dissect any website, from TailwindCSS to GitHub, revealing the tech stack in a neat, easy-to-read breakdown.
Beyond Apps: The Full Tech Takedown
CRFT Lookup isn’t a one-trick pony. It goes way beyond spotting Shopify apps, offering a 360-degree view of a website’s tech profile. Here’s what you get:
- Tech Stack Breakdown: From React and NextJS to Cloudflare and AWS, see the frameworks, CMS platforms, and infrastructure powering a site.
- Lighthouse Scores: Integrated Google Lighthouse metrics grade performance, accessibility, SEO, and best practices. Is that site fast or just flashy? Now you know.
- Meta Tag Previews: See how a site looks when shared on Google, Facebook, WhatsApp, or Slack. Perfect for ensuring your site’s social glow-up is on point.
- Sitemap Visualization: Explore a site’s structure with an interactive tree view, revealing page hierarchy and navigation paths. It’s like a map to the website’s soul.
Whether you’re benchmarking your Shopify store against the big dogs or analyzing a competitor’s site, these insights help you spot gaps, steal ideas (ethically, of course), and optimize like a pro.

Keeping It Ethical (and Free!)
Let’s address the elephant in the room: CRFT Lookup only scans publicly accessible data. No sneaking into private code or spilling sensitive secrets—it’s all above board, analyzing what’s already out there. Think of it as reading the label on a jar, not cracking it open.
Oh, and did we mention it’s free? Yup, unlimited scans, no credit card required. How do they make money? By selling top-notch web design and development services, not by nickel-and-diming you for reports. Reports are shareable via unique URLs, saved for 30 days, and packed with all the juicy details—perfect for collaborating with your team or impressing a client.
The Fine Print on Shopify App Detection
Now, to clear up any confusion: CRFT Lookup doesn’t provide detailed app descriptions, pricing, or specific roles in the Shopify ecosystem for detected apps. Instead, it identifies the apps (like Klaviyo or Privy) and categorizes them based on their technical signatures. For deeper insights, you’ll need to research the apps yourself—but CRFT gives you the starting point.
Its accuracy is solid, thanks to a regularly updated detection engine that cross-references multiple indicators. However, it can only spot apps with public-facing components—custom or heavily obfuscated setups might slip through.
Ready to Snoop?
Whether you’re a Shopify merchant plotting your next move, a developer hunting for tech inspiration, or just a curious web nerd, CRFT Lookup is your go-to tool for uncovering the tech behind any site. Fire up a scan, share the results, and start building smarter. Who knows? You might just discover the secret sauce that takes your site from “meh” to “marvelous.”
