GameFlow vs InputPlumber

GameFlow is free, cross-platform gamepad tooling that routes gamepad, keyboard, mouse, or phone input through saved profiles to virtual-controller output. Mapping options include autofire, remapping, shift layers, SOCD cleaning, stick trim, gyro aiming, touchpad mapping, button combos, and freeze macros. Custom control logic can be written in sandboxed Lua through MoonSharp. Profiles are editable JSON documents that users can create, duplicate, rename, import, and export. A phone browser on the same local network can act as a controller without an installed app, with support for up to 16 phones. GameFlow can generate a transparent controller-overlay URL for an OBS Browser source, and its motion server exposes DSU/Cemuhook over UDP for Cemu, Dolphin, Yuzu, and Ryujinx. The application requires .NET SDK 10.0 or later and uses SDL3 for gamepad and joystick input on Windows, Linux, and macOS. Windows virtual output uses HIDMaestro in user mode; Linux and macOS virtual gamepad output are not built yet.
