NanoVG
NanoVG is an open C vector library inspired by the Canvas API with paths, gradients, text, and OpenGL backends.
Why use it
Debug overlays, editor widgets, and small game UIs gain high-quality 2D drawing quickly.
Where it fits
Find engines, frameworks, code libraries, version control, and production automation.
What to check
Upstream is stable but limited; complex layout, modern GPU backends, and accessibility need other solutions.
