Best Free & Open Source Alternatives to Strava

Geo Activity Playground is a Python-based tool for analyzing and visualizing GPS-tracked outdoor activities. It processes activity files from various sources (GPX, FIT, TCX) and generates insightful statistics, maps, and visualizations about your workouts.

Unlike cloud-based fitness platforms, this tool runs entirely on your local machine, giving you full control over your data without uploading anything to third-party servers. It provides heatmaps, elevation profiles, activity calendars, and various performance metrics.

What is Ryot?

Ryot (Roll Your Own Tracker) is a self-hosted platform for tracking every facet of your media consumption and fitness journey from a single interface. Built in Rust and TypeScript, it centralizes logging for movies, TV shows, anime, manga, books, audiobooks, podcasts, music, and video games alongside workout logs, body measurements, and exercise progress.

Key features

• Unified tracking across 9+ media types and fitness in one app
• One-click imports from Trakt, Goodreads, MyAnimeList, Audiobookshelf, Plex, Jellyfin, Emby, Kodi, and more
• Automatic scrobbling via integrations with Jellyfin, Plex, Kodi, and Emby
• Workout logger with a comprehensive exercise database and detailed progress graphs
• Body measurements tracking with historical charts
• GraphQL API for custom integrations
• OpenID Connect authentication and notifications via Discord, Ntfy, or Apprise
• PWA support for mobile use
• Single Docker container backed by PostgreSQL

How it compares

Unlike Trakt (limited to movies and TV) or Goodreads (books only), Ryot covers your entire media diet in one place while also handling fitness tracking that would otherwise need Strava, Hevy, or FitNotes. Your data lives in your own PostgreSQL database, and automatic scrobbling from media servers (Jellyfin, Plex, Emby, Kodi) means nothing is sent to third parties. A paid Ryot Pro tier adds profile sharing, personalized recommendations, and enhanced collections, but the core platform is fully usable without spending a cent.

CubeTrek is a web application designed to visualize, share, and manage GPS tracks with a focus on outdoor activities in mountainous and hilly terrain such as skiing, mountaineering, mountain biking, and trail running.

Unlike traditional 2D tracking apps, CubeTrek renders your adventures in realistic 3D topography. It features TrekMapper to reveal your most frequented spots, a replay mode to relive activities interactively, activity matching to benchmark past performances, and comprehensive dashboards with calendar heatmaps and performance metrics.

CubeTrek supports importing FIT, GPX, and ZIP files, and can sync with third-party services like Garmin Connect, Polar Flow, and Coros. It is open source under GPL-2.0.

Endurain is a self-hosted fitness tracking service designed to give users full control over their data and hosting environment. It is similar to Strava but focused on privacy and customization.

Built with Vue.js and Python, Endurain supports importing data from various fitness devices and apps, tracks activities like running, cycling, and hiking, and provides detailed statistics and visualizations. The service includes features such as gear tracking, sleep scoring, health monitoring, and single sign-on support.

Endurain is fully self-hostable via Docker and offers multi-language support. It is licensed under AGPL-3.0.

RunnerUp is a free and open-source running tracker for Android devices. It tracks your running, cycling, and other outdoor activities using GPS, providing detailed statistics about pace, distance, heart rate, and elevation.

It supports various workout plans and integrates with external heart rate monitors. The app is designed to be lightweight and privacy-focused, keeping your fitness data on your device rather than in the cloud. It can also export data to various formats for use with other platforms.

OpenTracks is a sport tracking application that completely respects your privacy. It is an Android app that records your outdoor activities via GPS, supports Bluetooth LE sensors (heart rate, cycling speed/distance/cadence/power, running speed/cadence), and provides voice announcements and photo markers — all without requiring internet access, displaying ads, or using Google Play Services.

Tracks can be exported as KMZ, KML, or GPX files, and the app includes a public API for integration with automation tools like Tasker. OpenTracks is based on Google's discontinued My Tracks app and has been heavily reworked to remove all proprietary dependencies and analytics.

Compared to Strava, OpenTracks offers a completely offline experience with no social features or cloud sync, making it ideal for users who prioritize privacy and local data ownership over community engagement and competitive leaderboards.
