godotGem For Linux

godotGem is one of the most niche apps out there. It's a free, open-source, and cross-platform app that allows you to connect a controller over the network, as well as turn your steam deck into a controller, or use any controller from a Linux PC on Windows.

In short, the app has various interesting use cases, even though they're not for everybody. For instance, your computer/laptop doesn't have a free USB port for connecting your controller, as this app effectively makes the connection wireless, or you need an extra controller and all you have lying around you is a Steam Deck.

It's also handy if you want to connect a Linux computer to a Windows machine over the network, as this app allows you to bind an emulated controller on Windows to the same inputs you're doing on Linux, if that makes sense.

godotGem is not particularly stylish, but it's not bad either. You get a series of buttons, as well as a so-called "Blinder" button that fades the screen to black so that your Steam Deck doesn't have burn-in while sending its inputs over to the other computer.

It's also worth noting that the app uses ViGEm.NET, Godot, and webSockets to make everything happen. Hence, you'll need to manually install ViGEm and godotGem servers on your computer before being able to use the app.

The list of tested controllers is as follows: DualSense, DualShock 4, Logitech Gamepad F310, Nintendo Switch Pro Controller, Steam Controller, Steam Deck, and Xbox One (+series).

godotGem is without a doubt a very interesting app that might be of interest to a select few users who really want or need an app that allows them to use the controllers from one computer to another.
