Capture and automate macOS UI with the Peekaboo CLI.

Peekaboo

Peekaboo is a full macOS UI automation CLI: capture/inspect screens, target UI elements, drive input, and manage apps/windows/menus. Commands share a snapshot cache and support --json/-j for scripting. Run peekaboo or peekaboo <cmd> --help for flags; peekaboo --version prints build metadata. Tip: run via polter peekaboo to ensure fresh builds.
