CRFT Lookup doesn’t just mutter, “It’s Vue.” It delivers a full tech rundown—free, sharp, and with a dash of charm.
How CRFT Lookup Works Its Magic
So, how does CRFT Lookup play framework detective? It’s like a code-whisperer, analyzing bundle signatures, DOM structures, and technical patterns. With a database of over 2,500 technology fingerprints, it spins up a headless Chromium instance to scan any URL you throw at it. In a heartbeat, it IDs frameworks like React, Vue, or Next.js, plus other tech like UI libraries and analytics tools.
Drop a website’s URL into CRFT Lookup, and it’ll hunt for framework clues left in public-facing code. It’s not just about frameworks, though—this tool can dissect any site, from GitHub to PostHog, serving up a tidy tech stack summary that’s easy to grok.
Beyond Frameworks: The Full Tech Takedown
CRFT Lookup isn’t here to half-bake it. It goes all-in, giving you a panoramic view of a website’s tech profile. Here’s the full spread:
- Tech Stack Breakdown: From Angular and Gatsby to Cloudflare and AWS, see the whole crew of frameworks, CMS platforms, and infrastructure.
- Lighthouse Scores: Google Lighthouse metrics rate performance, accessibility, SEO, and best practices. Is that site smooth or just shiny? You’ll know.
- Meta Tag Previews: Peek at how a site looks when shared on Google, Facebook, or Slack. Keep its social game flawless.
- Sitemap Visualization: Explore a site’s structure with an interactive tree view, mapping pages and navigation like a digital cartographer.
Whether you’re fine-tuning your site’s frontend or scoping out a competitor’s tech, these insights help you spot gaps, borrow brilliance (ethically, naturally), and code like a rockstar.

Keeping It Ethical (and Free!)
Let’s squash any concerns: CRFT Lookup only scans publicly accessible data. No creeping into private code or spilling sensitive secrets—it’s all above board, just reading what’s out there. Think of it as checking a website’s public GitHub repo, not hacking the server.
Oh, and it’s free. Unlimited scans, no wallet required. How do they make money? By selling top-notch web design and development services, not by charging for reports. Share your reports via unique URLs, stored for 30 days, and packed with all the details—perfect for team collabs or client show-offs.
The Fine Print on Framework Detection
To keep it real: CRFT Lookup doesn’t serve up detailed framework features, ecosystems, or use cases. It identifies frameworks (like React or Svelte) and categorizes them based on their technical signatures. For the deep dive, you’ll need to research the framework yourself—CRFT just hands you the starting point.
Its detection is solid, thanks to a regularly updated engine that cross-checks multiple indicators. But it can only spot frameworks with public-facing components—heavily optimized or custom builds might stay incognito.
Ready to Snoop?
Whether you’re a developer crafting the next big app, an architect planning a scalable frontend, or just a web-curious coder, CRFT Lookup is your go-to for uncovering the tech behind any site. Fire up a scan, share the results, and build smarter. You might just find the secret sauce that takes your site from “meh” to “mind-blowing.”
