WebGPU is a new technology that works in most, but not all, web browsers. It enables faster, more powerful computations with your computer’s graphics processing unit (GPU) in web applications like Asunder Knit.

Your device will need to support WebGPU to run Asunder Knit’s simulation feature. Typically this is a hardware (i.e. the computer chip inside your device) limitation. Nevertheless, the core charting features will work on all devices. Please refer to the following sections pertinent to your type of device for more information.

WebGPU on Mobile

Android

You will need Android 12+ and Chrome 121+ on a compatible, modern device. Android hardware varies the most, and WebGPU support is the most variable for Android devices. Typically, Android devices will require a recent ARM-based chip or Qualcomm Snapdragon chip.

Not all Android devices that support WebGPU will have it enabled; you may need to turn it on yourself. Visit the URL “chrome://flags” in your Android browser, search for “WebGPU”, and enable “Unsafe WebGPU.”

iPad & iPhone

You will need iPadOS 26+ or iOS 26+ where WebGPU will be enabled by default. Earlier versions of the Apple operating systems do not support WebGPU. If your device cannot update to version 26 or greater, the hardware is too old and not compatible.

On *some* iOS/iPadOS 18.x devices, you can enable experimental WebGPU through “Settings → Apps → Safari → Advanced → Feature Flags → WebGPU → ON.” However, reliability cannot be guaranteed.

WebGPU on Desktop

For desktop computers (running Windows, macOS, or Linux), most devices are able to run WebGPU in a modern browser. For Windows and macOS, WebGPU is fully supported in Chrome 121+, Safari 26+, and Firefox 145+. For Linux, WebGPU is supported in Chrome 144+ but this is still dependent on the computer’s GPU hardware, driver, and distro. Firefox for Linux does not have reliable support yet.
