Contrack is a self-hosted contact management and personal CRM application that combines contacts from Apple, Google, LinkedIn, Facebook, calendars, and inboxes. Its four-step workflow imports contacts, deduplicates matching profiles, enriches records from notes or cited web research, and tracks follow-ups, birthdays, milestones, and conversation history on each person's timeline. It provides private plain-language search across contacts and notes, automatic reminders from dated phrases such as "next Tuesday," morning follow-up briefings, a map view, shared family or team accounts with separate address books, verified backups, exports, attachments, tags, and a command palette. It can connect to Claude, ChatGPT, or Cursor through MCP for contact lookups and note logging, while search runs locally. Contrack runs on a personal computer or home server with Docker, Docker Compose, or from source, storing data in a local volume. The repository also offers a browser demo with fictional contacts and describes the application as open-source and privacy-focused.

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.

MTL Explorer is a self-hosted GPS track and trail log for a personal computer, NAS, home lab, or server. It imports Garmin, GPX, and FIT tracks, displays thousands of activities on maps, calculates track statistics, replays routes with a cinematic 3D camera, and supports route planning through BRouter. The application is distributed as a Docker Compose stack with a Spring Boot backend, a Vue 3 and TypeScript progressive web app, an OpenAPI schema, and optional sidecars for BRouter, local vector maps, and GeoNames SQLite location search. It is licensed under AGPL-3.0-or-later, with a separate commercial license for users who do not want to comply with the AGPL terms.

wanderer is a self-hosted trail database for making recorded GPS tracks and planned routes searchable. It lets users upload tracks or create routes, add metadata, notes, and photos, view them through map integrations, share trails, and organize them into custom lists. Search and filtering support trail-catalogue queries such as distance, elevation, and difficulty. The project can be deployed with Docker Compose or run on bare metal and is licensed under AGPLv3.

Reitti is a self-hosted personal location-tracking and analysis application developed by Dedicated Code. It builds an interactive timeline and map from GPS data, identifying visits and trips, estimating transport modes such as walking, cycling, and driving, recording raw tracks, recognizing significant places, and providing movement statistics. It imports GPX, Google Takeout JSON, Google Timeline Export, and GeoJSON files, and accepts real-time data from OwnTracks, GPSLogger, Overland, Home Assistant, and its REST API. Reitti supports multi-device tracking, manual correction and stitching of GPS points, custom map styles, and integration with a self-hosted Immich server to place photos on the timeline. It can share live locations through same-instance or federated connections and revocable magic links, optionally including a recent track. The application is deployed with Docker, supports multi-user isolation and OIDC login, and is licensed under AGPL-3.0.
