PatternCraft is a small, free gallery of ready-made CSS and Tailwind background patterns and gradients, geometric tiling, decorative effects, built for copy-paste use rather than browsing finished illustration files.
You get working CSS immediately, not an image you then have to figure out how to position as a background.
Useful for a developer who wants a decent-looking site background in under a minute and doesn't want to touch a design tool at all.
Listed at over 250 patterns and described by the maker as "100% free," no account or download step, just copy the snippet shown on screen.
