Durves is a tiny free tool for creating customizable wavy dot-matrix patterns — the kind of subtle background you see on landing pages and UI hero sections. You tweak proportion, dot radius, amplitude, wave frequency, and color, and the canvas re-renders in real time; export to PNG or SVG when you're done.

It's built and open-sourced by Filipe Esteves, funded by optional PayPal donations, and also published as a Framer plugin for designers who'd rather generate patterns inside Framer. A perfect example of the small, single-purpose, free utility this directory exists to surface.
