What is Sparkyfitness?
SparkyFitness is a comprehensive self-hosted fitness tracking application that serves as a privacy-first alternative to MyFitnessPal. It helps users monitor nutrition, exercise, body measurements, water intake, and health goals all in one unified platform. Built with modern web technologies (React 18, TypeScript, Node.js, PostgreSQL) and designed for self-hosting via Docker, it gives users complete control over their personal fitness data.
Key features include nutrition tracking with meal logging and custom food creation, exercise logging with a comprehensive exercise database, body measurement tracking with progress visualization, hydration monitoring, goal setting, daily check-ins, and an AI-powered nutrition coach (SparkyAI) that allows chat-based food logging with image recognition. The app supports multi-user profiles for family use, offers interactive charts and comprehensive reports, and integrates with Apple Health, Google Health Connect, Fitbit, Garmin Connect, Strava, and Withings.
SparkyFitness is designed for privacy-conscious fitness enthusiasts, families who want to track health data together, and self-hosting enthusiasts who prefer keeping their health data on their own servers rather than in the cloud. It is open source under the MIT License and is currently in active beta development with over 3,600 users on GitHub and 52 active developers contributing.
