About
Hammerspoon is a free, open-source macOS automation tool that bridges the operating system to a Lua scripting engine. Users write Lua scripts to interact with macOS APIs covering windows, audio, keyboard, wifi, batteries, and much more. It supports a plugin system called Spoons for pre-built automation workflows.
Problem
macOS lacks a flexible, programmable automation layer that lets users script complex interactions across system APIs.
For
macOS power users and developers who want to automate their desktop environment
How it works
Users write Lua scripts in a config file that connect system events (keypresses, wifi changes, battery levels, etc.) to custom actions via Hammerspoon's extensive extension API.
