Deploy and Host true-nutri-backend on Railway

TrueNutri Backend is a secure Go API that powers AI-driven nutrition tracking for mobile apps. It eliminates security vulnerabilities by moving sensitive API keys server-side while providing fast, reliable food analysis through Gemini AI integration and seamless Supabase data management.

About Hosting true-nutri-backend

Hosting true-nutri-backend involves deploying a containerized Go application that serves as a secure proxy between your Flutter mobile app and AI services. The backend handles authentication via Supabase JWT tokens, processes food images through Gemini AI for nutritional analysis, and stores results in your Supabase database. Railway's automatic deployments, environment variable management, and built-in scaling make it ideal for this production-ready API that requires zero-downtime updates and reliable performance for mobile users.

Common Use Cases

Mobile App Security: Eliminate API key exposure in Flutter/React Native apps by moving all AI processing server-side
AI-Powered Food Analysis: Process food images through Google's Gemini AI with secure authentication and rate limiting
Nutrition Data Management: Store and retrieve meal analysis results with user authentication and data privacy controls
