What you give up either way

  • Proprietary, production-grade food image model and the vendor's claimed 2s avg scan time
  • Polish of a published iOS/Android app (store listings, reviews, continuous UX improvements)
  • Any proprietary mappings or curated food-item disambiguations beyond USDA matching
  • Built-in badges, habit heuristics, and cross-user analytics or personalization

An open-source project doing the core job proves a replacement is possible. It does not prove it matches Calchi AI, and it does not prove anyone has run it for a month. How we decide.
