About the Project

Training infrastructure that respects athletes

Endurance athletes feed years of intimate training data into proprietary U.S. platforms such as TrainingPeaks, Strava, and Garmin Connect, with little practical say in how that data is processed, monetized, or retained.

OpenAthlete is a different proposition: comparable tracking and analysis in an open-source stack, hosted in the EU when you use managed infrastructure, self-hostable when you prefer your own hardware, and with training-load logic you can read and adapt in the repository. It is maintained by an ultra-trail runner based in Grenoble.

Key Features

• 🇪🇺 EU-Hosted & GDPR-Native — Data processed in the European Union
• 🔒 You Own Your Data — Self-hostable, full export, no lock-in
• 🔍 Transparent Algorithms — Training load formulas (CTL/ATL/TSB) are in the code, auditable, customizable
• 📊 Comprehensive Tracking — Workouts, fitness/fatigue/form metrics, progression visualizations
• 🔗 Device Integrations — Activities from Strava, Garmin, Polar and Suunto; planned workouts sent to Garmin and Suunto watches (Coros coming); FIT and GPX file import
• 📱 On your phone — Installable web app on iPhone and Android; iOS app in beta (TestFlight)
• 🤖 AI Assistance — Modest helpers for session generation and load monitoring (not a replacement for a coach)
• 🌐 Open Source — AGPLv3, community-driven, sustainably funded

Getting Started

To get a local copy up and running, please follow these simple steps.

Prerequisites

Here is what you need to be able to run OpenAthlete.

• Node.js (Version: >=22.14.0) - We recommend using nvm for version management
• pnpm (Version: >=9.x) - Fast, disk space efficient package manager
• PostgreSQL (Version: >=13.x) - Database
• Git - Version control

If you want to enable AI features, you may need to obtain API credentials. More details can be found in the documentation.

Development

Setup

1. Clone the repo into a public GitHub repository (or fork https://github.com/openathleteorg/openathlete/fork):

   git clone https://github.com/openathleteorg/openathlete.git
   cd openathlete
   

2. Install packages with pnpm

   pnpm install
   

3. Set up your environment variables

   • Frontend: Copy apps/web/.env.example to apps/web/.env and update with your configuration
   • Backend: Copy apps/api/.env.example to apps/api/.env and update with your configuration
   • At minimum, you'll need:
     • DATABASE_URL - PostgreSQL connection string
     • JWT_SECRET - Secret key for JWT tokens (generate with openssl rand -base64 32)
     • VITE_API_URL - Backend API URL (for frontend)

4. Setup Node version

   If your Node version does not meet the project's requirements, use nvm:

   nvm use
   

   You first might need to install the specific version and then use it:

   nvm install && nvm use
   

5. Build shared packages

   pnpm shared build
   

6. Set up the database using Prisma

   In a development environment, run:

   pnpm database run db:migrate dev
   

   In a production environment, run:

   pnpm database run db:deploy
   

7. Run (in development mode)

   pnpm dev
   

   This will start:

   • Frontend at http://localhost:5173
   • Backend API at http://localhost:3000

Development Tips

2. Run type checking before committing:

   pnpm tsc:check
   

3. Format and lint your code:

   pnpm format:write
   pnpm lint:fix
   

Upgrading from earlier versions

1. Pull the current version:

   git pull
   

2. Check if dependencies got added/updated/removed

   pnpm install
   

3. Apply database migrations by running one of the following commands:

   In a development environment, run:

   pnpm database run db:migrate dev
   

   In a production environment, run:

   pnpm database run db:deploy
   

4. Check for .env variables changes

   Compare your .env files with the .env.example files to see if new variables were added.

5. Start the server. In a development environment, just do:

   pnpm dev
   

   For a production build, run for example:

   pnpm build
   pnpm start
   

6. Enjoy the new version.

Deployment

Self-hosting with Docker

On any server with Docker and its Compose plugin:

curl -fsSL https://raw.githubusercontent.com/openathleteorg/openathlete/main/scripts/install.sh | sh

OpenAthlete then runs on http://localhost from the published images, with new random secrets in openathlete/.env. Add -s -- --domain openathlete.example.org to serve your domain over HTTPS with automatic certificates. Run the script again to update.

The self-hosting guide covers HTTPS, device sync, AI, backups and upgrades from older setups.

Manual Deployment

For detailed deployment instructions, see our self-hosting documentation.

Backend (NestJS)

1. Build the application:

   cd apps/api
   pnpm install
   pnpm build
   

2. Set up environment variables in .env

3. Run database migrations:

   pnpm database run db:deploy
   

4. Start the server:

   pnpm start:prod
   

Frontend (React + Vite)

1. Build the application:

   cd apps/web
   pnpm install
   pnpm build
   

2. Serve the built files using a web server (nginx, Apache, etc.)

   Example nginx configuration:

   server {
       listen 80;
       server_name your-domain.com;
   
       root /path/to/apps/web/dist;
       index index.html;
   
       location / {
           try_files $uri $uri/ /index.html;
       }
   }
   

Environment Variables

Backend Required Variables

DATABASE_URL="postgresql://user:password@host:5432/openathlete"
JWT_SECRET="your-secret-key"
NODE_ENV="production"

Frontend Required Variables

VITE_API_URL="https://api.your-domain.com"

For a complete list of environment variables, see the .env.example files in each app directory.
