glfw/glfw

GLFW is a multi-platform library for creating windows, contexts, and surfaces for OpenGL, OpenGL ES, and Vulkan applications.

The library solves the problem of writing platform-specific window and input handling code by providing a simple, platform-independent API. It abstracts away the differences between Windows, macOS, and Linux (supporting both Wayland and X11), allowing developers to write graphics applications once and deploy them across multiple operating systems. The core is written in C99 with Objective-C components for macOS support, keeping dependencies minimal and compilation straightforward.

Developers should choose GLFW if they are building graphics applications that need to run on multiple platforms without managing platform-specific windowing code themselves. It suits projects ranging from simple OpenGL tutorials to complex Vulkan applications. The library requires only CMake and platform headers during compilation, with no external SDK dependencies beyond what your operating system provides. Pre-compiled binaries are available for Windows and macOS, reducing setup friction. The project supports older systems including Windows 7 and macOS 10.11, though some Linux features like window decorations on GNOME Wayland benefit from optional additional packages.

The project maintains comprehensive documentation including guides, tutorials, and API references available both online and in release archives. Development activity shows consistent attention to compatibility across compilers including Visual C++, GCC, Clang, Clang-CL, and MinGW-w64. The repository includes no submodules, instead bundling small dependencies directly, which simplifies the build process. Release artifacts include source archives and binaries for major platforms, with detailed release notes documenting new features and deprecations for each version.
