Open Food Facts

NutriTrace is a self-hosted personal nutrition tracker developed by TraceApps. It runs as a single Docker container and provides a browser Progressive Web App and a native Android app for food diaries, meal and recipe logging, calorie and nutrition goals, adaptive TDEE tracking, intermittent fasting, manual activities, and wellness data. It can use Open Food Facts and USDA data, import recipes from Mealie, and integrate with Fitbit via Google Health, Withings, Garmin, and Health Connect. Its Trace AI features can read diary and wellness data, log food or activities conversationally, and propose food entries from photos for user confirmation. It also exposes selected diary, goal, and food data to external AI agents through an opt-in, read-only Model Context Protocol endpoint. The project supports multi-user access and OIDC single sign-on, provides migration tools for several nutrition trackers, and distributes its server as a Docker image. The source is licensed under AGPL-3.0; the project states that it has no telemetry or cloud synchronization unless a user opts into a third-party integration.

openGym is a free, open-source gym and body-weight tracker with an Android app and Docker-based self-hosting. It provides guided workouts with previous weights, timed rest periods, personal-record notifications, weekly routines, supersets, cardio, timed sets, warm-up sets, and progression rules including linear progression, Greyskull LP, double progression, and added time. The tracker records workout history, body weight, RIR or RPE effort ratings, estimated one-rep maxes, and progress through charts, muscle-balance, fatigue, strength, and training-heatmap views. It can import histories from FitNotes, Strong, Hevy, and Apple Health exports, and export routines as files or PDFs. The project states that it requires no account, cloud service, or telemetry; its code, releases, container images, and APK builds are distributed under the AGPL-3.0 license.

OpenStock is an open-source stock market web application developed by Open Dev Society. It provides stock search, watchlists, company profiles and financial information, market news, TradingView charts and market widgets, personalized alerts, and support for more than 30 international exchanges. It is a market-information app rather than a brokerage, and data may be delayed according to provider limits. The application uses Next.js, React, TypeScript, Tailwind CSS, shadcn/ui, Better Auth, MongoDB, Finnhub, and TradingView widgets. Inngest runs background workflows for AI-personalized welcome emails and scheduled news summaries; optional sentiment insights use Adanos across sources including Reddit, X.com, news, and Polymarket. It can run locally or with Docker Compose, using MongoDB for persistence and Finnhub credentials for market data. The repository is licensed under AGPL-3.0, including source-release requirements for modified, redistributed, or deployed versions.

wger is a free, open-source, self-hosted fitness and workout manager developed by the wger project. It supports custom workout routines with automatic weight-progression rules, diet and calorie logging using a food database sourced from Open Food Facts, body-weight and custom-measurement tracking, progress photos, and a built-in exercise wiki. The application can be deployed with Docker and provides Android, iOS, F-Droid, and Flathub clients, multilingual support, multi-user accounts with basic gym-management features, and a REST API for integrations and automations. Application code is licensed under AGPL-3.0-or-later; exercise and ingredient data and documentation have separate licenses.

OpenAnalytics is an open-source, self-hostable web analytics stack developed by OpenLabs. It uses a lightweight browser tracker without cookies, fingerprinting, or cross-site profiles, and provides aggregate-only analytics for page views, custom events, sessions, web vitals, funnels, retention, embeddable widgets, public sharing, live presence, and Stripe revenue attribution. The repository is a pnpm monorepo comprising a tracker, ingestion collector, queue worker, API, ClickHouse query gateway, realtime SSE service, Next.js dashboard, and CLI. Postgres stores control-plane data, ClickHouse stores events and rollups, and Valkey provides the event queue and realtime cache. The query gateway is the only component permitted to read ClickHouse and verifies Ed25519-signed query envelopes; visitor identity uses a salted hash that rotates nightly, while optional city-level geolocation is resolved against a database on the host. It also includes CSV/JSON import and export, an MCP server, and an AI assistant. The project is licensed under AGPL-3.0. It can be self-hosted with Docker Compose, or used through the authors' hosted instance at getopen.so. Release images are published to GitHub Container Registry.
