A single-header C++ pixel drawing and UI framework for game development, visualization, and education.
olcPixelGameEngine is a single-header C++ framework for creating pixel-based graphics applications, including games, algorithm visualizations, and educational tools. It provides a fast, feature-rich environment for drawing pixels and handling user input across multiple platforms. The project simplifies low-level graphics programming by bundling essential functionality into one easy-to-use file.
C++ developers interested in game development, graphics programming, algorithm visualization, or educational projects who want a lightweight, cross-platform alternative to larger game engines.
Developers choose olcPixelGameEngine for its minimal setup—just one header file—and its flexibility for prototyping and learning. It offers a balance between low-level control and ease of use, with an active community and ports to other languages.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Requires only one header file, olcPixelGameEngine.h, drastically simplifying project setup and dependency management as highlighted in the README.
Supports Windows and Linux out of the box, with community ports extending to macOS, PSP, and Nintendo Switch, enabling development across diverse hardware.
Allows easy addition of features like 2D affine transforms, 3D software rendering, and sound through modular extensions, making it adaptable for various projects.
Regularly maintained with ports in C#, Rust, Lua, and Java, backed by a large community that contributes to ongoing development and resources.
macOS version is not yet officially released, relying on community contributions which may introduce instability or compatibility issues, as noted in the README.
Does not include integrated editors for assets, levels, or UI, requiring all game logic and content to be hand-coded, unlike full game engines.
Uses CPU-based software rendering, which can limit performance for complex scenes or high-resolution displays compared to GPU-accelerated frameworks.
