WebGPU Support Checker & Performance Report

The easiest way to check if WebGPU is enabled is right here on this website. Our top hero badge and environment metrics panel will immediately display if your browser supports the API.

If it is currently disabled or not supported:

• Google Chrome / Edge: WebGPU is enabled by default in version 113+. If you are on an older version or need experimental profiles, navigate to chrome://flags, search for "Unsafe WebGPU", and enable it.
• Mozilla Firefox: Go to about:config, search for dom.webgpu.enabled, and double-click to set it to true. Also verify that WebRender is enabled.
• Apple Safari: Available in Safari 18+ or inside Safari Technology Preview. Enable "WebGPU" inside Safari's "Developer" menu under "Feature Flags".

Yes, WebGPU is vastly superior to WebGL. WebGL is modeled on OpenGL ES 2.0/3.0, which was designed in an era of single-threaded GPU access and simple pipelines.

WebGPU is built from the ground up to reflect modern native graphics APIs like Vulkan (Windows/Linux), Metal (Apple Mac/iOS), and DirectX 12 (Windows). It offers key performance advantages:

• Lower CPU Overhead: WebGPU requires fewer browser validation checks during the main draw loop, freeing up the CPU.
• GPU Compute Shaders: Direct hardware execution for high-speed mathematical operations, critical for modern AI, ML, and physics simulation.
• Multi-Threading: WebGPU can record commands in parallel across multiple Web Workers, unlocking full multi-core CPU capacity.
• Modern Shader Language: Uses WGSL (WebGPU Shading Language), which is clean, robust, and compiles directly to native GPU code.

WebGPU in Chrome is the next-generation web-native API standard for rendering high-fidelity 3D graphics and conducting parallel computing. Released in Google Chrome 113, it provides direct, secure, and sandbox-isolated access to your system's underlying GPU hardware.

With WebGPU, Google Chrome lets web developers run complex LLM AI models, image generation, visual effects, and high-end video games locally inside the browser. It eliminates the distinction between web and native application capability by unlocking direct system hardware acceleration securely.

WebGPU serves as the foundation for modern web engineering, spanning multiple highly intensive compute domains:

• In-Browser AI & Machine Learning: Accelerates deep learning models like LLMs (WebLLM), transformers, stable diffusion, and computer vision models running 100% locally on your own GPU.
• Interactive Web Games: Enables desktop-grade 3D graphics, real-time lighting, advanced shading, and massive physics engines to run at 60+ FPS without installation.
• Data Visualization: Renders millions of real-time coordinates, geospatial nodes, and complex mathematical graphs smoothly.
• Image & Video Editing: Speeds up digital media encoding, rendering filter effects, video compositing, and texture processing in web apps like Canva or Figma.

WebGPU is the next-generation web standard graphics and compute API, developed by the W3C. It provides modern web applications with direct, secure access to your device's GPU hardware for high-performance 3D rendering and parallel computation.

Think of it as the spiritual successor to WebGL, built to match the capabilities of modern native APIs like Vulkan, Metal, and DirectX 12.

WebGPU is supported in Google Chrome 113+ (April 2023), Microsoft Edge 113+, Mozilla Firefox 141+ (stable, behind a flag in earlier versions), and Apple Safari 18+ (macOS 15 / iOS 18).

The API is also available in Chrome on Android, Safari on iPhone, and Chromium-based browsers like Brave, Opera, and Arc. You can verify your exact support status instantly using our diagnostic tool above.

No — WebGPU is not identical to any native API, but it is designed to closely mirror their modern architecture. It provides a unified, safe abstraction layer that maps efficiently to Vulkan (Windows/Linux/Android), Metal (Apple), and DirectX 12 (Windows).

This means developers can write WebGPU code once and have it run with near-native performance across all major platforms and hardware.

Yes. WebGPU is available on mobile devices running modern operating systems — Safari 18+ on iPhone and iPad (iOS 18 / iPadOS 18), and Chrome 113+ on Android.

Mobile GPU support is more limited than desktop, so certain advanced features (ray tracing, mesh shaders) may not be exposed. Our diagnostic tool reports your exact mobile adapter type, vendor, and supported features.

Mozilla Firefox supports WebGPU natively starting from Firefox 141 (stable channel, July 2025). On older versions, navigate to about:config in the address bar, search for dom.webgpu.enabled, and double-click to set it to true. You should also verify that gfx.webrender.all is enabled.

Restart Firefox and our diagnostic tool will confirm support.

WebGPU is enabled by default in Safari 18 and later on macOS Sequoia, iOS 18, and iPadOS 18.

If you are on an earlier version, install Safari Technology Preview and enable WebGPU via the Develop menu → Feature Flags → WebGPU. Restart Safari and visit our site to verify.

WGSL (WebGPU Shading Language) is the official shader language for WebGPU, designed for writing both vertex/fragment shaders and compute kernels.

It is strongly typed, readable, and compiles directly to the native shader languages of Vulkan SPIR-V, Metal MSL, and DirectX HLSL. WGSL replaces the need for GLSL or ESSL that WebGL used, offering better tooling, clearer syntax, and stronger safety guarantees.

Yes — WebGPU is one of the most powerful enablers for running AI and machine learning models entirely client-side. Frameworks like Transformers.js, MediaPipe, TensorFlow.js WebGPU backend, and WebLLM use WebGPU compute shaders to run LLMs, image generation (Stable Diffusion), computer vision, and speech recognition directly in your browser with GPU acceleration.

No server, no API costs, and full data privacy.

Yes. WebGPU is built with security as a first-class concern. All GPU access is sandboxed by the browser, validated for memory safety, and protected against timing attacks and shader-based exploits (similar to Spectre mitigations).

Untrusted shaders are compiled in a safe, deterministic environment, and the API prevents direct hardware access — meaning WebGPU is actually safer than older plugin-based graphics APIs.

Common reasons WebGPU fails include: an outdated browser (pre-Chrome 113, pre-Firefox 141, pre-Safari 18), disabled hardware acceleration in browser settings, outdated or blocked GPU drivers (especially on Linux or older Windows), running in an unsupported environment (e.g., WebView on some platforms), or privacy settings blocking the navigator.gpu API.

Use our diagnostic suite above — it tests every step of the initialization pipeline and reports the exact failure reason.

WebGPU defines minimum required hardware limits that all conformant implementations must support, such as maxTextureDimension2D (8192), maxBindGroups (4), maxStorageBufferBindingSize (128 MB), and maxComputeInvocationsPerWorkgroup (256).

Real hardware typically exceeds these minimums — for example, modern desktop GPUs may support 16K+ textures and gigabytes of buffer memory. Our System & Hardware Limits Report section above compares your device's supported values against the W3C spec minimums in real time.

The best starting point is the official W3C WebGPU specification, which doubles as a detailed reference. For hands-on learning, explore the WebGPU Fundamentals tutorial site, the MDN Web Docs WebGPU guide, and Google's WebGPU Samples repository on GitHub.

Our diagnostic tool is also a useful learning companion — it shows exactly what your hardware can do, which helps you set realistic parameters when writing your first compute or render pipelines.
