The Vulkan API is available on any Android device starting with API level 24 (Android Nougat), however not all devices will have a Vulkan driver.
Android uses its Hardware Abstraction Layer (HAL) to find the Vulkan Driver in a predefined path.
All 64-bit devices that were released with API level 29 (Android Q) or later must include a Vulkan 1.1 driver.
Vulkan is supported on the Fuchsia operation system.
Vulkan is not natively supported on iOS, but can still be targeted with Vulkan Portability Tools.
Vulkan is not natively supported on MacOS, but can still be targeted with Vulkan Portability Tools.
Some embedded systems support Vulkan by allowing presentation directly-to-display.
