## What it is
Mjolnir is a lightweight automation and productivity application for macOS that loads a Lua environment and lets users script common tasks via installable Lua modules. It is the predecessor to Hammerspoon and is configured through a ~/.mjolnir/init.lua file.

## Use cases
- automate window management on mac with lua scripts
- bind custom global hotkeys to move or resize windows
- script repetitive macos tasks
- control applications from a lua config
- build a personal productivity toolkit on os x

## When to choose
- you want a lightweight, scriptable automation app for macOS using Lua
- you prefer a minimal core extended via LuaRocks modules
- you want a Hammerspoon-style tool with a smaller footprint

## When to avoid
- you need an actively maintained tool with recent updates
- you prefer JavaScript or another scripting language over Lua
- you need a cross-platform automation solution
