A small tool that lets web apps access your GoldenCheetah data. It runs on your computer and keeps your data private. Nothing is sent to the cloud.
You don't need Python or any other programming tools installed. The commands below handle everything automatically.
macOS and Linux: open Terminal (on Mac: press Cmd+Space, type "Terminal", press Enter) and paste:
curl -LsSf uvx.sh/goldencheetah-proxy/install.sh | sh
Windows: open PowerShell (press the Windows key, type "PowerShell", press Enter) and paste:
powershell -ExecutionPolicy ByPass -c "irm https://uvx.sh/goldencheetah-proxy/install.ps1 | iex"
Important: After installing, close your terminal and open a fresh one. This is needed so your terminal picks up the newly installed command.
Open GoldenCheetah, then go to:
Settings → General → Integration → Enable API Web Services
Open a terminal (or PowerShell on Windows) and run:
goldencheetah-proxy
You should see:
GoldenCheetah Proxy v0.1.0
Proxy running on http://localhost:12022
Forwarding to GoldenCheetah at http://localhost:12021
Waiting for connections...
Leave this running while you use the web viewer.
Open goldencheetah-web-viewer/index.html in your browser and click Connect.
The proxy will ask you to approve the website. Click Allow (or type y in the terminal on Linux).
GoldenCheetah has a built-in API that runs on your computer. Browsers can't talk to it directly due to security restrictions (CORS). The proxy sits in between and adds the right headers so your browser can access the data.
Browser → Proxy (localhost:12022) → GoldenCheetah API (localhost:12021)
Your data never leaves your computer.
goldencheetah-proxy --port 9999 # Use a different port (default: 12022)
goldencheetah-proxy --gc-port 5555 # GoldenCheetah API port (default: 12021)
Building a web app that uses GoldenCheetah data? This repo includes an agent skill that teaches AI coding agents how to build against the proxy. Install it into your project with:
