WebGPU in 2026: High-Performance Graphics and Compute in the Browser

WebGPU brings modern GPU capabilities to the web, enabling high-performance graphics and compute workloads that were previously impossible in browsers.

WebGPU vs WebGL

• Modern API: Based on Vulkan/Metal/D3D12
• Compute Shaders: General-purpose GPU computing
• Better Performance: Lower driver overhead
• Explicit Control: Manage GPU resources directly

Getting Started

const adapter = await navigator.gpu.requestAdapter();
const device = await adapter.requestDevice();

const canvas = document.querySelector("canvas");
const context = canvas.getContext("webgpu");
context.configure({
  device,
  format: navigator.gpu.getPreferredCanvasFormat(),
});

// Create shader module
const shaderModule = device.createShaderModule({
  code: `
    @vertex fn vs(@builtin(vertex_index) i: u32) -> @builtin(position) vec4f {
      const pos = array(vec2f(0, 1), vec2f(-1, -1), vec2f(1, -1));
      return vec4f(pos[i], 0, 1);
    }
    @fragment fn fs() -> @location(0) vec4f {
      return vec4f(1, 0, 0, 1);
    }
  `
});
