Rebind is a free engine that makes your keyboard and mouse scriptable. Remap keys, expand text, run macros, smooth a tremor, or drive input from another program — the same Luau script on Windows, macOS, and Linux, with any USB keyboard and mouse you already own. How it works covers the engine itself.

FAQ

​
Is Rebind free?

Yes. Software mode is free forever and needs no hardware. A Rebind Link is a one-time purchase for hardware output.

​
Does Rebind work on macOS and Linux?

Yes. The same script runs unchanged on Windows, macOS, and Linux. See platforms for per-namespace details. No. Software mode uses your OS’s input APIs without any hardware. The Link adds hardware-isolated, deterministic output at up to 8,000 Hz.
