Rebind vs vendor software
G Hub, Synapse, and iCUE only program their own brand. Rebind remaps any USB keyboard and mouse on Windows and macOS, and Rebind Link adds hardware output.
Each vendor app programs only that company's hardware. Mix a keyboard from one brand with a mouse from another and you run two apps. Swap brands next year and you start over.
Rebind sits in front of any USB keyboard and mouse, whatever the brand. Your remaps move with you to another device or operating system.

Vendor apps give you per-device profiles. Rebind gives you Luau: coroutines, HTTP and WebSocket, screen sampling, per-app activation. Block an input, rewrite it, or fan one key into a sequence.
