Fenster is a minimal single-header C99 library for opening a cross-platform window with a 24-bit RGB framebuffer, plus keyboard/mouse input polling and audio playback. It offers a simple Arduino/Processing-style polling loop without callbacks or multithreading, with bindings for Go, Zig, and Lua.

Use cases

• draw pixels to a cross-platform 2D canvas in C
• build a minimal retro-style game with keyboard and mouse input
• play audio from a simple C program on Windows, macOS, and Linux
• teach graphics programming like old-school BGI or INT 10h demos
• prototype demoscene or software renderer experiments
• run Doom from a tiny C library

When to choose

• you want the smallest possible dependency for windowed 2D graphics in C
• you prefer a polling API over event callbacks and threading
• you need a teaching or prototyping tool for framebuffer graphics
• you want one header that works across Linux, macOS, and Windows

When to avoid

• you need widgets, menus, or a full GUI toolkit
• you need GPU-accelerated rendering or 3D graphics
• you need high-resolution or multi-window support
• you need robust production-grade input handling or accessibility features
