Download Klaus

Get the Klaus build for your system. The desktop app and the terminal command share one account and one configuration.

Klaus Desktop

An agent workspace for real tasks. Project sessions, the changes view, the Overview panel, messaging channels, scheduled tasks and the skill marketplace, all in one window.

Upgrading from 0.3.x: quit Klaus first, then install the new build. On macOS drag Klaus into Applications and replace the old app; on Windows run the installer. Your sessions, workspaces and settings are kept, though sites in your browser may need signing in again.

Klaus Cli

Klaus in your terminal. One command to install, and it reads the same configuration, skills, plugins and MCP servers as the desktop app.

macOS
curl -fsSL https://klaus-ai.cn/install.sh | sh

Installs to ~/.klaus/bin without sudo. The script verifies the sha256 before writing to disk.

Windows
curl -fsSLo install.bat https://klaus-ai.cn/install.bat && install.bat

Installs to %LOCALAPPDATA%\Klaus\bin and adds it to your user PATH. No admin rights needed.
