go-webgpu

Zero-CGO WebGPU bindings for Go — GPU-accelerated graphics and compute in pure Go

Pure Go WebGPU bindings using goffi + wgpu-native. No CGO required.

Requirements

• Go 1.25+
• wgpu-native v24.0.3.1 (download)

Installation

go get github.com/go-webgpu/webgpu

Download wgpu-native and place wgpu_native.dll (Windows) or libwgpu_native.so (Linux) in your project directory or system PATH.

Quick Start

package main

import (
    "fmt"
    "log"

    "github.com/go-webgpu/webgpu/wgpu"
)

func main() {
    // Initialize library
    if err := wgpu.Init(); err != nil {
        log.Fatal(err)
    }

    // Create WebGPU instance
    instance, err := wgpu.CreateInstance(nil)
    if err != nil {
        log.Fatal(err)
    }
    defer instance.Release()

    // Request GPU adapter
    adapter, err := instance.RequestAdapter(nil)
    if err != nil {
        log.Fatal(err)
    }
    defer adapter.Release()

    fmt.Printf("Adapter: %#x\n", adapter.Handle())
}

Examples

Example	Description
triangle	Basic triangle rendering
colored-triangle	Vertex colors and buffers
textured-quad	Textures, samplers, index buffers
rotating-triangle	Uniform buffers, animation
cube	3D rendering with depth buffer
instanced	Instanced rendering (25 objects in 1 draw call)
compute	Compute shader parallel processing
indirect	GPU-driven rendering (DrawIndirect)
render_bundle	Pre-recorded draw commands
timestamp_query	GPU profiling with timestamps
mrt	Multiple Render Targets
error_handling	Error scopes API

Run examples:

cd examples/triangle && go run .
