Kawa

Kawa is a macOS utility that lets users switch input sources using custom keyboard shortcuts. It replaces the default input‑method selector with a configurable hotkey system, allowing rapid changes between languages or keyboard layouts without navigating menus. The application runs as a standard macOS bundle and can be installed via Homebrew or by downloading a prebuilt binary from the project's release page.

The tool targets macOS users who frequently change input sources, such as multilingual typists or developers working with various keyboard layouts. It offers a straightforward interface for defining shortcuts and integrates with the operating system’s input‑source APIs. A known limitation exists with complex CJKV input sources due to a macOS Carbon library issue.
