# Coder Desktop

Coder Desktop provides seamless access to your remote workspaces through a native application. Connect to workspace services using simple hostnames like `myworkspace.coder`, launch applications with one click, and synchronize files between local and remote environments, all without installing a CLI or configuring manual port forwarding.

<Callout type="success" title="Tip">
  Coder Desktop provides **automatic port forwarding** to every service running in your workspace. Any port your application listens on is instantly accessible at `workspace-name.coder:PORT` with no manual setup required. For a comparison of all port forwarding methods, see [Workspace Ports](/docs/@v2.35.3/user-guides/workspace-access/port-forwarding/).

## What You'll Need

* A Coder deployment running `v2.20.0` or [later](https://github.com/coder/coder/releases/latest)
* Administrator privileges on your local machine (for VPN extension installation)
* Access to your Coder deployment URL

## Quick Start

1. Install: `brew install --cask coder/coder/coder-desktop` (macOS) or `winget install Coder.CoderDesktop` (Windows)
2. Open Coder Desktop and approve any system prompts to complete the installation.
3. Sign in with your deployment URL and session token
4. Enable "Coder Connect" toggle
5. Access workspaces at `workspace-name.coder`

## How It Works

**Coder Connect**, the primary component of Coder Desktop, creates a secure tunnel to your Coder deployment, allowing you to:

* **Access workspaces directly**: Connect via `workspace-name.coder` hostnames
* **Automatic port forwarding**: All workspace ports are available at `workspace-name.coder:PORT` with no configuration
* **Use any application**: SSH clients, browsers, IDEs work seamlessly
* **Sync files**: Bidirectional sync between local and remote directories
* **Work offline**: Edit files locally, sync when reconnected

The VPN extension routes only Coder traffic—your other internet activity remains unchanged.

        ```
      </Tab>

      <Tab value="Manual Installation" id="manual-installation-1">

## Testing Your Connection

Once connected, test access to your workspaces:

<Tabs items="[&#x22;SSH Connection&#x22;, &#x22;Ping Test&#x22;, &#x22;Web Services&#x22;]" groupId="coder-docs-tab:ping-test-ssh-connection-web-services" persist="true">
  <Tab value="SSH Connection" id="ssh-connection">
    ```shell
    ssh your-workspace.coder
    ```
  </Tab>

  <Tab value="Ping Test" id="ping-test">
    ```shell
    # macOS
    ping6 -c 3 your-workspace.coder

    # Windows
    ping -n 3 your-workspace.coder
    ```
  </Tab>

  <Tab value="Web Services" id="web-services">
    Open `http://your-workspace.coder:PORT` in your browser, replacing `PORT` with the specific service port you want to access (e.g. 3000 for frontend, 8080 for API)
  </Tab>
</Tabs>

## Administrator Configuration

Organizations that manage Coder Desktop deployments can configure the application using MDM (Mobile Device Management) or group policy.

### Disable Automatic Updates

Administrators can disable the built-in auto-updater to manage updates through their own software distribution system.

<OSTab items="[&#x22;macOS&#x22;, &#x22;Windows&#x22;]">
  <Tab value="macOS" id="macos-1">
    Set the `disableUpdater` preference to `true` using the `defaults` command:

    ```shell
    defaults write com.coder.Coder-Desktop disableUpdater -bool true
    ```

    Organization administrators can also enforce this setting across managed devices using MDM (Mobile Device Management) software by deploying a configuration profile that sets this preference.
  </Tab>

  <Tab value="Windows" id="windows-1">
    Set the `Updater:Enable` registry value to `0` under `HKEY_LOCAL_MACHINE\SOFTWARE\Coder Desktop\App`:

    ```powershell
    New-Item -Path "HKLM:\SOFTWARE\Coder Desktop\App" -Force
    New-ItemProperty -Path "HKLM:\SOFTWARE\Coder Desktop\App" -Name "Updater:Enable" -Value 0 -PropertyType DWord -Force
    ```

    You can also configure a `Updater:ForcedChannel` string value to lock users to a specific update channel (e.g. `stable`).

    <Callout type="info" title="Note">
      For security, updater settings can only be configured at the machine level (`HKLM`), not per-user (`HKCU`).
    </Callout>
  </Tab>
</OSTab>

## Troubleshooting

### Connection Issues

#### Can't connect to workspace

* Verify Coder Connect is enabled (toggle should be ON)
* Check that your deployment URL is correct
* Ensure your session token hasn't expired
* Try disconnecting and reconnecting Coder Connect

#### VPN extension not working

* Restart Coder Desktop
* Check system permissions for network extensions
* Ensure only one copy of Coder Desktop is installed

### Collecting Logs

When reporting an issue, attach the relevant log files so we can diagnose it faster.

<OSTab items="[&#x22;macOS&#x22;, &#x22;Windows&#x22;]">
  <Tab value="macOS" id="macos-2">
    Coder Desktop and its network extension write to the Apple [unified logging system](https://developer.apple.com/documentation/os/logging). The file sync (Mutagen) daemon writes to a separate log file.

    1. Export the unified logs for the last hour with the `log` command:

       ```shell
       log show --predicate 'subsystem == "com.coder.Coder-Desktop"' \
         --info --debug --last 1h > ~/Desktop/coder-desktop.log
       ```

       Adjust `--last` (e.g. `30m`, `2h`, `1d`) to cover the time the issue occurred. You can also view the same logs interactively in **Console.app** by filtering on the `com.coder.Coder-Desktop` subsystem.

    2. If you're using file sync, also collect the Mutagen daemon log:

       ```shell
       ~/Library/Application\ Support/Coder\ Desktop/Mutagen/daemon.log
       ```

       Coder Desktop also opens this file in Console automatically when the file sync daemon fails.
  </Tab>

  <Tab value="Windows" id="windows-2">
    Coder Desktop has three components that write logs: the app (UI), the VPN service, and the file sync (Mutagen) daemon.

    1. App log (daily rolling):

       ```powershell
       %LOCALAPPDATA%\CoderDesktop\app.log
       ```

    2. VPN service log (default install path):

       ```powershell
       C:\Program Files\Coder Desktop\coder-desktop-service.log
       ```

    3. File sync (Mutagen) daemon log, if you use file sync:

       ```powershell
       %LOCALAPPDATA%\CoderDesktop\mutagen\daemon.log
       ```

    You can quickly open the app log directory by pasting `%LOCALAPPDATA%\CoderDesktop` into File Explorer.

  Before attaching logs to a public issue, review them for any sensitive information (deployment URLs, usernames, hostnames) and redact as needed.
