Portable core remaps, with hardware output.

If you write AutoHotkey, you already think the way Rebind works: bind a key, transform an input, fire a hook, run a macro. Rebind's scripting language is Luau, a fast, typed member of the Lua family. The model carries straight over.

AutoHotkey is Windows-only and sends input at the software level. Rebind's core remap and HID APIs run on Windows, macOS, and Linux. OS-specific APIs such as Registry, Pipe, App, Window, and Screen differ by platform. With Rebind Link, output leaves a dedicated USB device as standard HID.

The full engine is free. Hardware isolation and a USB report rate of up to 8,000 Hz in hardware mode come with Rebind Link.

AutoHotkey:

CapsLock::Escape

Rebind, the same remap, and it runs on macOS and Linux too:

-- rebind: name=CapsLock to Escape
-- rebind: version=1.0.0
-- rebind: min_sdk=3.0.0

Bind.Remap("CapsLock", "Escape")

AutoHotkey:

#HotIf WinActive("ahk_exe Photoshop.exe")
^j::Send("^+s")
#HotIf

Rebind, where the modeline scopes the whole script, so there are no per-binding guards:

-- rebind: name=Photoshop Save As
-- rebind: version=1.0.0
-- rebind: min_sdk=3.2.2
-- rebind: process=Photoshop.exe

Bind("LCtrl+J", function()
  HID.Combo("LCtrl+LShift+S")
  return false
end)

Use AutoHotkey when you're on Windows only, want the deepest, most mature ecosystem of scripts and docs, and software-level output is all you need.

Use Rebind when you want portable core remaps across Windows, macOS, and Linux; standard USB HID output from dedicated hardware; a built-in HTTP/WebSocket runtime; or clients for TypeScript, Python, and Rust.

Use both: keep your AutoHotkey setup on Windows and port the scripts you want portable or hardware-backed to Rebind.

Can I run my exact AutoHotkey scripts in Rebind? No. Scripts are Luau, not AHK syntax. But the model is the same, porting is straightforward, and RebindGPT can draft a port from a plain-English description.

Does Rebind work on macOS and Linux? Yes. Remaps, binds, macros, text expansion, and HID output run on Windows 10/11, macOS on Apple Silicon, and Linux x86_64. A few deeper OS integrations are Windows-first today. The platform support matrix lists what each platform supports.
