High-performance 2D UI layout library in C
Clay is a high-performance 2D UI layout library written as a single C header file that implements a flexbox-like layout model with microsecond-level performance. It uses static arena-based memory allocation with no malloc or free calls, keeping total memory usage under 4MB for thousands of elements. Clay is renderer-agnostic, outputting sorted rendering primitives that work with any 3D engine, SDL, or can compile to HTML via WebAssembly.
