Worried your site looks slapped together by AI? The worry is warranted — AI builders repeat a handful of signals, and most are visible right in the browser.
Design signals you can see
- Purple→indigo gradients repeat across hero, buttons, and badges
- Every section is centered and each card has rounded-2xl + a big shadow
- The hero has moving beams, spotlights, or aurora backgrounds
- The font is the default sans, uncustomized
- Emoji (✨🚀) repeat in headings
Technical signals in the code
- Builder badges/scripts left in (cdn.gpteng.co, lovable-tagger, v0 meta tags)
- Component-kit classes visible (background-beams, border-beam, animate-spotlight)
- Source maps (.map) or .env shipped to production
- API keys hardcoded in the frontend bundle
Check it all at once
Rather than checking each item, paste a URL into a tool that shows your stack and a vibe score. VibeCheck inspects builder artifacts, component-kit fingerprints, design patterns, and deploy hygiene at once, with a per-item fix. Ubiquitous tech like Tailwind or React never counts, so it only flags what's actually mass-produced.
