What do people build with it?

USE CASE 1

Replace raw Vulkan C API calls in a C++ game or rendering engine with safer, more expressive C++ wrappers.

USE CASE 2

Use automatic handle types to manage Vulkan object lifetimes without manually tracking when to destroy them.

USE CASE 3

Catch enum and bit flag mistakes at compile time instead of getting silent incorrect behavior at runtime.

USE CASE 4

Install via the LunarG Vulkan SDK or vcpkg to add Vulkan-Hpp to an existing graphics project.

Requires the LunarG Vulkan SDK and a working Vulkan-capable GPU, prior Vulkan knowledge is expected.

Apache 2.0, use freely in personal or commercial projects, including closed-source software, just keep the license notice.

So what is it?

Vulkan is a low-level graphics API used to write software that talks directly to a computer's graphics card, typically for games, 3D rendering engines, or other high-performance visual applications. Working with the original Vulkan C API involves a lot of manual bookkeeping: managing memory, tracking objects, and handling errors without much help from the language itself. Vulkan-Hpp is a set of C++ header files that wrap the same underlying Vulkan API and add the conveniences C++ programmers expect. The main improvements it provides are type safety for enums and bit flags (so the compiler catches mistakes that the C API would silently accept), support for standard library containers, exception-based error handling rather than checking return codes manually, and three families of handle types that manage object lifetimes automatically in ways similar to how C++ smart pointers work. All of this happens at compile time, so there is no additional cost when the program actually runs. The repository itself is primarily a code generator: it reads the official Vulkan XML specification published by Khronos and produces the C++ header files from that spec. This means Vulkan-Hpp stays in sync with new Vulkan versions as the spec is updated. Installation is straightforward. The headers are included in the LunarG Vulkan SDK, which is the recommended way to get them. They are also available through the vcpkg and Conan package managers for projects that use those tools. The project is maintained by Khronos, the industry group that also maintains the Vulkan specification itself, and is licensed under Apache 2.0.

Copy-paste prompts

Prompt 1
I'm using raw Vulkan in C++ and want to switch to vulkan-hpp. Show me how to create a VkInstance using the vulkan-hpp wrappers instead of the C API.
Prompt 2
How does vulkan-hpp handle Vulkan object lifetime automatically? Explain the three handle families and when to use each one.
Prompt 3
I'm getting a Vulkan error code back from an API call. Show me how vulkan-hpp turns that into a C++ exception and how to catch it.
Prompt 4
Walk me through adding khronosgroup/vulkan-hpp to a CMake project using vcpkg, what's the minimum setup?
Prompt 5
How does the vulkan-hpp code generator work? I want to understand how it reads the Vulkan XML spec and produces the C++ headers.
