SHOW DEV: 초가공 식품 및 팜유를 노출하기 위해 제로 로그인 식료품 스캐너를 제작했습니다.

Hey everyone! 👋
I got frustrated with modern supermarket shopping. Over 70% of food on grocery shelves is now Ultra-Processed (UPF), packed with hidden industrial seed oils, synthetic emulsifiers, and artificial food colorings.
Worse yet, most existing grocery scan apps force you to download a 100MB mobile app, create an account with email, and navigate aggressive subscription paywalls — all while you’re standing in the aisle with 5 seconds to choose.

So I spent the last few weeks building UnwrapTruth — a 100% free web app that turns your mobile browser into an instant supermarket scanner with zero login friction.

🚀 What it does:

• 📷 Instant Barcode & Camera OCR Scanner: Scan barcodes or snap a photo of any ingredient label to decode what’s really inside.
• 🚨 NOVA 4 Ultra-Processed Classification: Automatically flags ultra-processed markers, chemical emulsifiers, and artificial sweeteners.
• 🌿 30+ Hidden Palm Oil Aliases: Detects disguised derivatives like Palmitate, Elaeis Guineensis, and Glyceryl.
• ⚖️ Nutri-Score 2024 Algorithm: Real-time nutrient traffic lights across sugars, saturated fats, sodium, fiber, and protein.
• ⚔️ Side-by-Side Versus Mode: Compare two competing products head-to-head on a single screen.
• 🥑 Clean Alternative Swaps: Recommends healthier, seed-oil-free brand alternatives sitting right next to the junk on supermarket shelves.

– 🥫 Digital Clean Pantry: Save your household staples locally with zero tracking.

🛠️ The Tech Stack:

• Framework: Next.js (App Router, Server-Side Rendering)
• Styling: Vanilla CSS & Tailwind CSS for high-performance responsive layout
• Data: Open Food Facts global taxonomy graph + custom NOVA & harmful additive heuristics
• AI / Vision: Gemini API for label OCR extraction

– Hosting: Vercel (Edge-cached worldwide)

I’d love to get feedback from the dev community on the scan speed, UI responsiveness, and features you’d like to see next!
