## Auto Update

The desktop client has built-in auto-update. When a new version is available it is detected automatically; you can also manually "Check for updates" from the menu in the bottom-left corner and upgrade with one click.

## Desktop vs. Command-line Deployment

- **Desktop client**: best for personal use on your own computer — works out of the box, GUI-based, auto-updating.
- **Command-line deployment**: best for developers or long-running servers with more customization. See [Quick Start](/guide/quick-start).

## Access from a Browser

Once the desktop client is running, it listens on port `9876` locally, and its backend is exactly the same Web console. So while the app is open you can also just point your browser at `http://localhost:9876` for the same full experience as the client UI.

## Local Data Storage

All data of the desktop client is stored on your machine:

- **Config directory**: `~/.cow` in your home folder, holding `config.json` (model keys, channels, etc.) along with logs, cache and other runtime data.
- **Workspace**: `~/cow` by default, holding chat history, knowledge base, memory, skills, scheduled tasks and other files produced by the Agent.

Uninstalling the client does not delete these two directories, so your data is preserved across reinstalls. To fully clean up or migrate to another device, just back up or remove the corresponding folders manually.
