Key Features

• Track multiple domains such as books, movies/TV, games, workouts, and habits
• Imports from popular services (e.g., Goodreads, Trakt, Strong App)
• Integrations with media servers and players (e.g., Jellyfin, Plex, Emby, Kodi, Audiobookshelf)
• OpenID Connect authentication support
• Notifications to third-party services (e.g., Discord, ntfy, Apprise)
• PWA support for an app-like mobile experience
• GraphQL API for programmatic access and integrations
• Analytics and summaries with charts to understand trends and progress

Use Cases

• Maintain a private personal catalog of watched/read/played media with reviews and history
• Track workouts and fitness routines alongside other personal metrics
• Replace spreadsheets with a unified dashboard and automated imports/integrations

Ryot is a good fit for homelab and privacy-conscious users who want a single system to record and analyze personal activity across media and health domains, with extensibility via integrations and its API.

SparkyFitness is a full-stack, open-source fitness tracking application for logging nutrition, workouts, water intake and body measurements. It provides a web PWA and an Android client, optional Garmin integration, and an AI-powered chat assistant (SparkyAI) for natural-language food logging and image-based meal recognition.

Key Features

• Nutrition logging with custom foods, categories and interactive charts.
• Exercise logging and a searchable exercise database.
• Water intake and daily check-ins to track habits.
• Body measurements tracking with progress charts and goal management.
• AI Nutrition Coach (chat-based food logging, image uploads, chat history).
• Web PWA, Android mobile app, optional Garmin microservice, and Docker-based deployment.

Use Cases

• Individuals or families who want a self-hosted alternative to commercial fitness trackers.
• Users who want AI-assisted food logging and image recognition for meal entries.
• Developers and self-hosting enthusiasts deploying a full-stack app using Docker and PostgreSQL.

Limitations and Considerations

• Several features are noted as beta/under heavy development (AI Chatbot, multi-user/family access, Apple Health sync); expect potential breaking changes and migration work during upgrades.
• The project is intended for self-hosting and requires configuring environment variables, database migrations, and optional external API keys for food providers.

SparkyFitness is a comprehensive, privacy-focused option for users who prefer to self-host their fitness data, offering a modern React front end, Node/Express backend and PostgreSQL storage with Docker deployment support.

Perfice is an open-source, local-first self-tracking platform that lets you track arbitrary metrics (sleep, mood, habits, etc.), set goals, and surface correlations between metrics. The client is a web app (Svelte + TypeScript) with an optional backend for account sync and integrations.

Key Features

• Trackables: define and record any metric or event with flexible value types
• Automatic correlations: compute and surface relationships between metrics to reveal patterns
• Goals: create and monitor goals across multiple trackables
• Local-first storage: primary data storage and calculations use browser storage (IndexedDB) for privacy and offline-first use
• Exportability: export and import data in CSV and JSON formats
• Mobile support: packaged for Android via a native WebView wrapper (Capacitor) for on-device use
• Optional backend & sync: user accounts, multi-device synchronization and integrations are supported via an optional server
• Customizable UI and workflows, built with modern web stack for easy theming and extension

Use Cases

• Personal habit and behavior tracking to discover what affects mood, sleep, or productivity
• Wellness monitoring and correlation analysis for sleep, exercise, and mood patterns
• Quantifying progress toward goals and visualizing metric trends over time

Limitations and Considerations

• Multi-device sync and account features require deploying and configuring the optional backend; the backend is not required for single-device local use
• As a local-first app using browser storage, very large datasets may be constrained by the client environment and browser IndexedDB limits
• Mobile distribution relies on building the native wrapper; additional steps and tooling are needed to produce store-ready mobile packages

Perfice is suited for users who want a privacy-conscious, extensible self-tracking tool with built-in insights and goal support. It balances a local-first experience with optional server-backed sync for multi-device workflows.

Clean Slate is an open-source calorie tracker web application designed for fast, compassionate food logging. It emphasizes caloric awareness while minimizing perfectionism by tracking only calories and protein and by encouraging a daily "fresh start" approach.

Key Features

• Simple food search and quick-add calories/protein for fast logging
• Barcode scanning powered by Open Food Facts to import product nutrition
• Create and log custom foods and recipes; track meals and exercise
• GraphQL API (Hasura) for querying logs, foods, recipes, and profiles
• Two authentication options: simple apiToken-based auth or optional Firebase social login
• Deployable via Docker Compose with PostgreSQL backend and Caddy reverse proxy
• Mobile-friendly web client built in TypeScript with a lightweight, speed-first UX

Use Cases

• Personal calorie and protein tracking for weight management or nutrition awareness
• Support for people recovering from disordered eating who need a gentle, non-judgmental tracker
• Self-hosted deployments for users requiring privacy and control over their data

Limitations and Considerations

• Default apiToken auth stores long tokens in the database and lacks email/password flows; Firebase adds complexity to set up
• Barcode coverage depends on Open Food Facts data; some products may be missing or incomplete
• No official native mobile apps; the service is primarily a responsive web client

Clean Slate is focused on simplicity and evidence-based education to teach sustainable tracking habits. It is suitable for individuals who want a fast, privacy-conscious tracker and for operators who prefer self-hosted deployment via Docker Compose.

Calorific is a minimal, dead-simple self-hosted calorie tracker implemented in PHP. It provides an easy interface to log meals, reuse saved meals and ingredients, and monitor progress against a daily calorie target without micromanaging macronutrients.

Key Features

• Log individual meals and entries with timestamped records
• Save and reuse commonly used meals and ingredients to speed logging
• Build log entries from saved meals or ingredient lists, and compose saved meals from ingredients
• Set a daily calorie goal and preview how a new entry will affect daily progress
• Built-in update mechanism for the application
• Options for hour offsets to accommodate server time differences
• Utility features for cleaning up the log database and hiding the control panel

Use Cases

• Track daily calorie intake for weight loss, maintenance, or gain with minimal overhead
• Maintain a reusable list of common meals and ingredients for fast logging
• Lightweight self-hosted alternative for users who do not need detailed macro tracking

Limitations and Considerations

• Focuses on calories only; it does not provide detailed macronutrient tracking or advanced nutrition analysis
• No documented API or official mobile apps; primarily a web interface intended for single-user or small private use
• Developed and tested on a typical AMP stack (Apache + MySQL) — other web servers or SQL engines may require additional configuration

Calorific is suited for users who want a straightforward, private calorie log without complex features. It is lightweight, easy to deploy on an AMP stack or via Docker, and emphasizes quick logging and simple progress tracking.
