Vulkan Loader

This project provides the Khronos official Vulkan Loader for all platforms except Android


Vulkan is an explicit API, enabling direct control over how GPUs actually work. As such, Vulkan supports systems that have multiple GPUs, each running with a different driver, or ICD (Installable Client Driver). Vulkan also supports multiple global contexts (instances, in Vulkan terminology). The ICD loader is a library that is placed between a Vulkan application and any number of Vulkan drivers, in order to support multiple drivers and the instance-level functionality that works across these drivers. Additionally, the loader manages inserting Vulkan layer libraries, such as validation layers, between an application and the drivers.

This repository contains the Vulkan loader that is used for Linux, Windows, MacOS, and iOS. There is also a separate loader, maintained by Google, which is used on Android.

Version Tagging Scheme

Updates to this repository which correspond to a new Vulkan specification release are tagged using the following format: v<version> (e.g., v1.3.266).

Note: Marked version releases have undergone thorough testing but do not imply the same quality level as SDK tags. SDK tags follow the vulkan-sdk-<version>.<patch> format (e.g., vulkan-sdk-

This scheme was adopted following the 1.3.266 Vulkan specification release.
