cliclick

Scriptable mouse and keyboard events, for automating apps that expose no API.

What it does

cliclick synthesises input events: move the cursor, click, double-click, drag, scroll, type a string, press modifiers and key codes. Coordinates are absolute screen pixels, and a w: command inserts waits between steps.

cliclick m:500,300 c:. w:200 t:"hello"
cliclick kd:cmd t:s ku:cmd      # Cmd-S
cliclick p                       # print current cursor position

Notes

Needs Accessibility permission in System Settings; without it commands are accepted and silently do nothing.
Coordinate-based automation is brittle across display changes. Prefer AppleScript or Shortcuts when the target app is scriptable, and keep cliclick for the ones that are not.

Alternative to

Alternative	Type	Trade-off
AppleScript / `osascript`	Built in	Scripts the app properly when the app supports it
Hammerspoon	Open source	Lua, and far more capable for anything conditional
Keyboard Maestro	Paid	A recorder and image-based targeting
Shortcuts	Built in	The supported route, when the app exposes actions
