NutriTrace

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.

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.

Trace is an AI-powered browser developed by Breadcromb that creates a private knowledge layer by unifying tabs, documents, and conversations and uses that context to assist the user. The product is described as local-first by default and is offered as a free download.

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.

getbased is an open-source, local-first personal health dashboard and self-hostable web application, with a hosted version at getbased.health. It combines laboratory results, DNA data, wearable and body metrics, light exposure, lifestyle context, therapy histories, and personal notes in a browser-based workspace. Lab reports can be imported from PDFs, images, and spreadsheets or entered manually; known markers are mapped for review, then tracked with charts and context-aware ranges. The application calculates supported ratios and indices through deterministic fallbacks, including biological age when the required inputs are available, and produces Biology Scores that summarize marker patterns rather than diagnose conditions. DNA support includes consumer and clinical raw-DNA formats, curated SNP interpretation, APOE haplotypes, and mitochondrial DNA haplogroups. The dashboard also supports selected wearable connections, local Apple Health file imports, manual measurements, light and environmental tracking, and structured therapy histories. It can run without an account and stores most data in the browser by default; AI analysis, encrypted synchronization, profile sharing, external Knowledge Bases, and Agent Access are opt-in. The project can be self-hosted or used through its hosted application.
