Quickstart	Quickstart	Integrate Subtrace with just one command	rocket

Subtrace is an API observability tool. It connects your backend to Chrome DevTools so that you can inspect the latency of each API request. We'll show you how you can start using Subtrace with just a single command.

Open a terminal and download Subtrace:

```bash
curl -fSLO "https://subtrace.dev/download/$(uname -s)/$(uname -m)/subtrace" && chmod +x ./subtrace
```

Run your backend server startup command with Subtrace:

<CodeGroup>
  ```bash Generic
  ./subtrace run -- my-app-command
  ```

  ```bash Node
  ./subtrace run -- node server.js
  ```

  ```bash Go
  ./subtrace run -- go run .
  ```

  ```bash FastAPI
  ./subtrace run -- fastapi run main.py
  ```

  ```bash Flask
  ./subtrace run -- flask --app hello run
  ```

  ```bash Gunicorn
  ./subtrace run -- gunicorn -w 4 myapp:app
  ```

  ```bash Laravel
  ./subtrace run -- php artisan serve
  ```
</CodeGroup>
