Overview

Description from the maker (original English)

Endurance training: activities, load, zones, and workouts sent to Garmin, COROS and Suunto watches

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 3 of 3 passed
  • Runs on the maker’s server: what you ask it goes through their server.
  • The registry lists no key to fill in.

Menu names can differ slightly by plan and over time.

Your choice stays on this device in a cookie; no account needed.

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

What it can do

The server asks you to sign in before it lists its tools.

Compared with others in Otheri

  • More stars than 0% of the other 32606 servers in this category
  • Published to the registry more recently than 90% of the other 32606 servers in this category
  • Basic checks equal to or better than 100% of the other 32606 servers in this category

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.

Common questions

Is OpenAthlete safe?

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.3.0) reached the registry 3 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

In the same category: Spec Driven Development, Remote Desktop Commander, Georgia MCP

Why OpenAthlete

Training platforms keep years of your data, charge coaches per athlete, and can be bought or shut down. Today's Plan closed in 2024; TrainingPeaks has belonged to Garmin since July 2026.

OpenAthlete is free on our servers in France and free on yours. The code is public under AGPL-3.0, the training-load formulas are in this repository, and you can export everything at any time. It is built by an independent developer and ultra runner in Grenoble, with no investors.

What it does

Plan. A calendar that thinks in seasons, weeks and sessions: training blocks, A/B/C races, illness and travel periods that move the sessions they cover, whole weeks copied or shifted with undo, and a calendar feed for Google, Apple or Outlook.

Build and sync. Structured workouts with targets from your own zones (pace, power, heart rate, % of VMA or FTP), a reusable library, and delivery to Garmin, COROS and Suunto watches at the next sync.

Analyse. Activities from Garmin, COROS, Suunto, Polar and Strava, or FIT, GPX and TCX files. Each interval graded against the plan, detected climbs, time in zones, aerobic decoupling, pace adjusted for gradient and weather, and non-destructive fixes for heart-rate spikes.

Progress. Records by distance and duration, year against year; critical speed and power; fitness, fatigue and form (CTL, ATL, TSB) from heart rate or perceived effort, projected over your planned sessions; HRV, resting heart rate and sleep from your watch. Every metric says what it measures and where it stops being reliable.

Coach. Compliance, volume and form for every athlete on one screen, alerts for reported pain, inactivity and unread messages, planning for several athletes at once, comments and real-time chat. Five athletes free, unlimited with Supporter.

AI, on your terms. Generate or edit a session from a sentence, get a short read of each activity and three questions on how it felt. Bring your own key (OpenAI, Anthropic, Google, Mistral, OpenRouter, DeepSeek, xAI, Groq, or a local model when self-hosted), pick the model per feature, or use the allowance included with Supporter. Nothing reaches an AI provider until you allow it. An MCP server lets Claude, ChatGPT or Cursor read your training and plan sessions straight into your calendar.

Mobile. The web app is built for phones and installs on the home screen. iOS and Android apps are in testing (TestFlight).

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

cd openathlete nvm use && pnpm install

PostgreSQL (with pgvector) and Redis

docker compose -f docker-compose.dev.yml up -d

Environment files, then edit them if needed

for f in apps/api apps/web libs/database; do cp $f/.env.example $f/.env; done

Prisma client, shared package, database

pnpm database run db:generate && pnpm shared build && pnpm database run db:deploy

pnpm dev # API on http://localhost:3000, web app on http://localhost:5173

Run the same checks as CI with scripts/verify.sh (add --integration, --build or --e2e for the slower suites).

Development Tips
  1. Run type checking before committing:
   pnpm tsc:check
  1. Format and lint your code:
   pnpm format:write

pnpm lint:fix

Upgrading from earlier versions
  1. Pull the current version:
   git pull
  1. Check if dependencies got added/updated/removed
   pnpm install
  1. 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
  1. Check for .env variables changes

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

  1. Start the server. In a development environment, just do:
   pnpm dev

For a production build, run for example:

   pnpm build

pnpm start

  1. 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.

Support OpenAthlete

OpenAthlete is built by one developer in Grenoble, supported by the community. There are three ways to help the project thrive:

- Become a Supporter on openathlete.org: €5/month or €50/year. It pays for the servers and adds AI on our keys and unlimited coached athletes.

- Buy a coffee: one-off support, even if you self-host. buymeacoffee.com/openathlete.

- Contribute: star the repo, open issues, send pull requests, translate, or join the Discord.

Self-hosting is fully supported and always free, with no limits. Supporters fund the project's long-term sustainability.

Roadmap

OpenAthlete is actively developed. Here's what's coming next:

  • 🧩 Modular Training Logic - Custom goals, coach import, and flexible training methodologies
  • 📈 Enhanced Dashboards - Intuitive data visualizations and performance analytics
  • 🔗 More Integrations - Wahoo, Zwift, Oura, and more
  • 👥 Clubs - Club accounts with several coaches and groups
  • 📱 Native apps - iOS and Android apps in the stores
