Go Reference gamen Matrix

gamen is cross-platform GUI window creation and management library in Go. It natively supports Windows, Linux, Android and Web. on Linux both X11 (via xcb) and Wayland are supported.

gamen provides consistent api for creating and managing GUI windows across different platforms. gamen also lets you handle events generated by platform window via callbacks. gamen is fairly low level, it provides platform native window handles for graphics APIs like OpenGL and Vulkan to initialize from, gamen by itself doesn’t provide you a drawing primitive you have to use a library like go-webgpu or similar.

gamen has a callback based api for handling events i.e it doesn’t do queueing (except for web backend) by itself. Because most of the backends already do internal queueing of events, doing it again inside the library can introduce unnecessary latency. Also this keep api flexible, a separate library can introduce event queue on top of gamen for easier developer experience.


package main

import (


func init() {

func main() {
	d, err := display.NewDisplay()
	if err != nil {
	defer d.Destroy()

	w, err := display.NewWindow(d)
	if err != nil {
	defer w.Destroy()

	w.SetCloseRequestedCallback(func() { d.Destroy() })

	for {
		if !d.Poll() {

		// render()

examples wgpu_poll and wgpu_wait shows how to use the event loop for a Game and a GUI respectively. Though an ideal client will switch between Poll and Wait. (GUI temporarily showing an animation)



windows (win32) backend does not use CGO, i.e does not require a C toolchain, only Go compiler is enough


resulting binaries shouldn’t require any dependency to be installed by the users. but developers will need some devel packages.


sudo dnf install wayland-devel libX11-devel libXcursor-devel libxkbcommon-x11-devel xcb-util-image-devel xcb-util-wm-devel


sudo apt install libwayland-dev libxkbcommon-x11-dev libx11-xcb-dev libxcb-randr0-dev libxcb-xinput-dev libxcb-icccm4-dev libxcursor-dev libxcb-image0-dev


android backend uses game-activity.

tsukuru should be used to help with dependency resolution and building the android app.

# make sure you have android sdk installed
# connect your device and setup adb connection / run android emulator

go install

tsukuru run apk ./examples/hello


web backend uses syscall/js package.

tsukuru can be used to help with automatically building wasm and copying wasm_exec.js & wasm_exec.html from $GOROOT to a directory and spinning up a local file server for you.

go install

tsukuru run wasm ./examples/hello

gamen‘s api is a mix of glfw and winit and some terminologies from Wayland.
