What WebGPU Is

WebGPU is a way for a web page to use your computer's graphics card directly. It is the successor to WebGL, and it is what lets a game built for the desktop run in a browser tab without a plugin or an install.

It is also new. Browsers have been switching it on one operating system at a time, so whether it works for you depends on which browser you use, which version it is, and what it is running on. If a game on this site told you that your browser does not have WebGPU, this page is for you.

Everything below was checked against each browser's own documentation on October 11, 2026. This is changing quickly, so if your browser is newer than the versions named here, try the game first.

The Short Version

• Windows, macOS or ChromeOS: use a current Chrome or Edge. Nothing to switch on.
• Mac: Safari 26 or newer works too (see the Safari section), and so does a current Firefox if your Mac has an Apple Silicon chip.
• Linux: Chrome works by default on some graphics cards. On others, and in Firefox, you have to switch it on by hand. Both are covered below.
• Whatever you use: update the browser first. Most of the time that is the whole fix.

Chrome and Edge

Chrome has had WebGPU switched on since version 113 on Windows, macOS and ChromeOS. Edge is built on the same engine and has had it since the same version.

On Android it has been on since Chrome 121, on phones running Android 12 or newer with a Qualcomm or ARM graphics chip. (The games here are desktop only for now.)

Linux is the newest addition:

• Chrome 144 switched it on for Intel graphics, 12th generation and newer.
• Chrome 147 added NVIDIA cards with a recent driver, when you are using Wayland.
• On anything else it is still behind a flag.

To switch it on by hand:

1. Open chrome://flags/#enable-unsafe-webgpu and set it to Enabled.
2. On Linux, also open chrome://flags/#enable-vulkan and set it to Enabled.
3. Restart Chrome.

To check that it worked, open chrome://gpu and look for the line WebGPU: Hardware accelerated.

If it still doesn't work:

• Open chrome://settings/system and make sure Use graphics acceleration when available is on. WebGPU is off whenever that setting is off.
• If chrome://gpu says "WebGPU has been disabled via blocklist or the command line", Chrome has decided not to trust your graphics card or its driver. Updating the driver is the first thing to try. The enable-unsafe-webgpu flag from the steps above also gets around that list.

Firefox

Firefox switched WebGPU on for Windows in version 141, and for Macs with Apple Silicon in version 147.

As of October 2026, on Linux and on Intel Macs it is not on in the regular release yet. It is only on by default in Firefox Nightly.

To switch it on:

1. Type about:config in the address bar, and accept the warning if one is shown.
2. Search for dom.webgpu.enabled.
3. Set it to true.
4. Restart Firefox to be safe.

This turns on something Mozilla has not finished testing on your system, so it may not run well, or at all. If it doesn't, Chrome is the easier route on Linux.

Safari

Safari added WebGPU in version 26 (September 2025). It is on by default in Safari 26 on macOS Tahoe 26, iOS 26 and iPadOS 26, so there is nothing to switch on.

Safari 26 also runs on macOS Sequoia and Sonoma. If WebGPU doesn't work there, update to macOS Tahoe or use Chrome.

If your Safari is older than 26, update it, or use Chrome.

Other Browsers

Brave, Opera and Vivaldi are built on the same engine as Chrome, so the Chrome section is the place to start. I could not find a statement from any of them about whether they leave WebGPU switched on, so if a game doesn't start there, try Chrome or Edge.

Still Not Working?

• Check whether your browser has WebGPU. Firefox and Safari have no page like chrome://gpu, so the simplest test is a game on this site: if it shows a note saying your browser can't run it instead of a Start button, WebGPU isn't available.
• Update your graphics driver. Chrome refuses WebGPU on graphics cards and drivers it knows to be broken.
• Check hardware acceleration. If it is turned off in your browser's settings, WebGPU is off with it.
• Try another browser. A current Chrome or Edge on Windows or macOS is the combination most likely to work.
