Grainient

Reach for this when a landing page needs a distinctive hero background and a CSS gradient or a Tailwind `bg-gradient-to-br` looks cheap — these are 4K–12K raster and video files, not code, so you ship them as an <img>/<video> layer or a CSS background-image, and you must budget for the file weight (compress to AVIF/WebP and set explicit dimensions). Everything except /freebies sits behind a paid login, so you cannot download assets for the user; link the collection and let them fetch it. If you need something generative and code-native instead, use the shader tool at shader.grainient.supply or a CSS/canvas gradient library.

Why it is here. One of the deepest single-author background libraries around — 61 curated packs beat a generic stock search, and the animated and shader pieces cover the motion case most gradient packs ignore.
