AdventureLog

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.

GeoLens is a self-hosted geospatial data catalog for collecting, indexing, previewing, and sharing GIS datasets on infrastructure controlled by one organization. It ingests uploaded and created datasets, database tables, service snapshots, and remote STAC assets, including Shapefile, GeoPackage, GeoJSON, GeoParquet, FlatGeobuf, KML/KMZ, CSV, XLSX, GeoTIFF, Cloud-Optimized GeoTIFF, and VRT raster mosaics. The catalog records dataset provenance and source state, supports pg_trgm fuzzy search and optional pgvector semantic ranking, and provides spatial analysis operations such as buffer, centroid, clip, dissolve, spatial join, and intersection. Its browser-based map builder composes and styles multi-layer maps and publishes them through links or embeddable iframes. GeoLens exposes OGC API Features and Records, STAC API 1.0, JSON-LD catalog formats, direct tile URLs, and vector tiles for use with QGIS, ArcGIS, MapLibre, and other OGC clients. The stack uses a React and MapLibre frontend, a FastAPI API, a GDAL/ogr2ogr ingestion worker, Titiler for raster tiles, PostgreSQL with PostGIS, pgvector, and pg_trgm, plus object storage and Valkey caching. The project is deployed with Docker Compose or prebuilt container images and also publishes Python, TypeScript/JavaScript, CLI, and read-only MCP packages. Optional AI features use an OpenAI-compatible endpoint or Anthropic key for natural-language dataset and map interactions. GeoLens is licensed under Apache License 2.0; its own REST API may change between minor releases, while its OGC and STAC standards surfaces are intended for client integration.

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.

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.
