# CLI dev command

> The `trigger.dev dev` command is used to run your tasks locally.

This runs a server on your machine that can execute Trigger.dev tasks:

<CodeGroup>
  ```bash npm
  npx trigger.dev@beta dev
  ```

  ```bash pnpm
  pnpm dlx trigger.dev@beta dev
  ```

  ```bash yarn
  yarn dlx trigger.dev@beta dev
  ```
</CodeGroup>

You will see in the terminal that the server is running and listening for requests. When you run a task, you will see it in the terminal along with a link to view it in the dashboard.

It is worth noting that each task runs in a separate Node process. This means that if you have a long-running task, it will not block other tasks from running.

## Options

### Attaching a local debugger

You can use the `--debugger` flag to run the server in debug mode. This will allow you to attach a debugger to the server and debug your tasks.

<CodeGroup>
  ```bash npm
  npx trigger.dev@beta dev --debugger
  ```

  ```bash pnpm
  pnpm dlx trigger.dev@beta dev --debugger
  ```

  ```bash yarn
  yarn dlx trigger.dev@beta dev --debugger
  ```
</CodeGroup>
