GameFlow

GameFlow suits players who want detailed control mapping across gamepads, keyboards, mice, and phone browsers. Its saved profiles and scripting make it adaptable to complex setups, while virtual gamepad output currently makes Windows the practical choice.

Overview

GameFlow brings input remapping, profile management, and virtual-controller output together in a free, open-source application. The breadth of its controls can accommodate setups that go beyond straightforward button swaps, and editable profiles let users carry configurations between sessions. The main qualification is platform-specific: Linux and macOS support input, but virtual gamepad output for those systems is not built yet.

Key features

Mapping and profiles

Controls include autofire, shift layers, SOCD cleaning, stick trim, multi-source rows, gyro aiming, touchpad mapping, button combinations, and freeze macros. That range is useful for players who need different behaviors across games or want several inputs to contribute to one control. Sandboxed Lua scripting through MoonSharp allows custom control logic, though it is a more involved option than basic remapping.

Profiles are human-editable JSON files that can be created, duplicated, renamed, imported, and exported. This gives users direct control over their setups and a practical way to share or organize them.

Phone, motion, and streaming tools

A phone browser on the same local network can act as a controller without a separate app, with support for up to 16 phones. That is a flexible extra input route, particularly for shared or improvised setups, though it depends on devices being on the same LAN.

The motion server exposes DSU/Cemuhook over UDP for Cemu, Dolphin, Yuzu, and Ryujinx, with the protocol supporting four pads. GameFlow can also generate a transparent controller overlay URL for an OBS Browser source, giving streamers a way to show controller activity on screen.

Pricing

GameFlow is free: the Free plan costs nothing and is open source in beta. It includes keyboard and mouse output, virtual-controller output, profile switching, and multiplatform support. There are no paid tiers to weigh against the free plan. Its MIT license permits use as-is, without warranties.

Platforms

GameFlow is listed for Windows, Linux, macOS, and web, and accepts gamepad, joystick, keyboard, mouse, and phone-browser input. The desktop application requires .NET SDK 10.0 or later and uses SDL3 for gamepad and joystick input on Windows, Linux, and macOS. Virtual-controller output is currently built for Windows through HIDMaestro in user mode, without a kernel driver or reboot. Linux and macOS users can use the input side, but cannot yet rely on GameFlow for virtual gamepad output.

One further limitation matters for some games: GameFlow does not hide physical controllers from games and has no HidHide or equivalent integration. That may rule it out where a game needs to see only the virtual controller.

Who it's for

GameFlow is a strong fit for Windows players who want layered mappings, custom Lua logic, motion support, or phone-browser input in one free tool. Its editable profiles also suit users who want to manage or exchange configurations directly. It is a weaker choice for Linux and macOS users who need virtual gamepad output, or for anyone whose setup requires hiding physical controllers.

Pros and cons

Pros

• Broad mapping controls, from autofire and shift layers to gyro aiming and freeze macros, support more involved control schemes.
• Human-editable JSON profiles can be imported, exported, duplicated, and renamed.
• Phone-browser input works over the same LAN without an app and supports up to 16 phones.
• Free and MIT licensed, with Windows virtual output that does not require a kernel driver or reboot.

Cons

• Virtual gamepad output is not built for Linux or macOS, despite input support on both.
• Physical controllers cannot be hidden from games through GameFlow, which can interfere with setups that need only virtual output visible.
• The desktop application requires .NET SDK 10.0 or later.
• The software is beta and its MIT license provides no warranty.

Alternatives

Consider Monect PC Remote Play if you want a freemium remote-control tool spanning Android, iOS, macOS, web, and Windows. Its free plan covers core PC remote-control features; Premium adds an ad-free experience and higher feature limits, while the 12-month plan is 12.00 CNY.

AntiMicroX is a free Linux and Windows desktop option if those are the platforms you need. ControllerBuddy is another free, open-source choice for Linux and Windows. For a free mapper specifically on macOS and Windows, DS5 Mapper is an alternative.

LEA Extended Input may suit users seeking free clients and server across Android, iOS, and Windows. On Windows, DS4Windows is a free application for Windows 10 or newer that requires .NET 8.0 Desktop Runtime, Visual C++ Redistributable, and ViGEmBus. FlexInput is a free MIT-licensed option for Windows 10/11 (x64). Linux users looking specifically for input-device remapping can consider Input Remapper, a free GPL-3.0 application.

Verdict

GameFlow is worth choosing for Windows players who want deep mapping controls, editable profiles, and extras such as phone-browser input and motion-server support without paying. Linux and macOS users should look elsewhere if they need virtual gamepad output, and players who must hide physical controllers should choose a tool with that capability.
