Browser Support in 2026

In September 2026, caniuse.com 3,038 puts WebGPU at 87.35% of global usage (85.72% full plus 1.63% partial), while MDN 102 still labels it Limited availability rather than Baseline, because Firefox 555 and Safari 10 do not enable it everywhere.

Where WebGPU is enabled by default (caniuse.com and the gpuweb Implementation Status wiki)
Browser	On by default since	Where
Chrome 1 , Edge	113 (2023)	Windows, macOS, ChromeOS; Android from 121
Chrome on Linux	144	Intel Gen12+ GPUs; NVIDIA on Wayland from 147
Safari	26 (September 2025)	macOS 26, iOS, iPadOS and visionOS 26
Firefox	141 (July 2025)	Windows; Apple Silicon Macs from 145

WebGPU exists only in secure contexts (HTTPS or localhost), on the main thread and in workers. Detect it in two steps, because navigator.gpu can exist while requestAdapter() returns null on a blocklisted GPU:
