glad is a loader-generator that produces multi-language bindings for Vulkan, OpenGL, GLES, EGL, GLX, and WGL based on official Khronos specifications.
The core problem glad solves is the tedious and error-prone task of manually writing or maintaining loader code for graphics APIs across different programming languages and platforms. Rather than hand-coding function pointers and extension queries, developers specify which API version and extensions they need, and glad generates the corresponding loader code automatically from the official specifications. This approach ensures correctness and consistency while eliminating boilerplate.
Developers should choose glad if they are building graphics applications in C, C++, Rust, Python, D, Nim, or Pascal and need reliable, specification-compliant loader code. It suits projects ranging from simple OpenGL applications to complex Vulkan renderers. The tool provides a web service for interactive generation, allowing developers to select exactly which API features they need rather than including unnecessary code. The project maintains examples for common scenarios including GLFW and SDL integration, multiple window contexts, and on-demand loading patterns. Community-maintained plugins extend language support beyond the built-in offerings.
The project shows consistent maintenance with regular updates to track specification changes and address user-reported issues. Development activity includes active engagement with community contributions and plugin development, indicating sustained interest in expanding language coverage. The codebase demonstrates attention to code quality through comprehensive examples and documentation that help users integrate generated loaders correctly into their projects.
