SFML

SFML works seamlessly on Windows, macOS, Linux, and other systems, providing a unified API that abstracts away platform-specific details, as highlighted in its cross-platform focus.

The library emphasizes simplicity and performance with a clean C++ interface, making it easy to manage windows, graphics, audio, and network without low-level boilerplate, per its philosophy.

Offers fast rendering of sprites, shapes, text, and images using hardware acceleration, ensuring smooth performance for real-time applications, as noted in the key features.

Distributed under the zlib/libpng license, SFML is free for any use, commercial or personal, with no attribution required, as explicitly stated in the README.
