Upload your raw DNA file. Get health & trait insights based on 120+ SNPs. Everything runs in your browser — your data never leaves your device.
🚀 Live Demo: gattaca.erdkse.com
Millions of people have raw DNA files from 23andMe, AncestryDNA, or MyHeritage sitting unused in a folder. GATTACA makes that data useful — privately and for free.
- 🔒 Privacy-first — All analysis runs client-side, no data sent to any server
- 🧬 120+ SNPs analyzed across 10 health & trait categories
- 📁 Multi-format support — 23andMe, AncestryDNA, MyHeritage, FamilyTreeDNA, LivingDNA (CSV/TSV/TXT)
- 🌍 Multi-language — English & Turkish (more welcome!)
- 📱 Responsive — Works on desktop and mobile
- 🌗 Dark mode — Automatic theme detection with manual toggle
