Spec score 7.7 #15 of 27 in Game Controller Mapper Software

What it is

Input Remapper is free Linux software for changing how input devices behave. It can map keys, mouse movements, joysticks, wheels, triggers, combinations and other inputs to different outputs, using either X11 or Wayland. In its graphical interface, you select a device, create a preset, add mappings and apply them. Optional macros provide cross-device variables, conditions and named parameters. Analog inputs can become analog outputs with adjustable sensitivity and non-linearity. Installation guidance covers Ubuntu/Debian, Fedora, Arch and Void, with manual installation described for other distributions. Version 2.0 and later requires at least Ubuntu 22.04. Reading `/dev/input/` events requires special permissions, so the interface requests a sudo password. Output symbols depend on the keyboard layout. The project is GPL-3.0 licensed and warns that game anti-cheat software might detect macros.
