Subtle — Background Generator

Subtle is a free tool for generating random, modern, minimalist, subtle backgrounds for marketing pages and hero sections. Choose from 18 generative styles — mesh gradients, glows, grids, dots, waves, flow fields, contours, rings, cross-ticks, halftone, and scenic scenes like mountains, ocean, island, city, peaks and orbits.

Every background is driven by a shareable seed, can be animated, and exports as SVG, CSS or PNG. There's also a drop-in React component. This app needs JavaScript enabled to run.
