What Grabient is

Grabient is a free web-based CSS gradient generator and palette manager. It creates gradients using Inigo Quilez’s cosine gradient technique, with controls for style, angle, and steps. Users can create, save, manage, browse, and like palettes, then search using descriptions such as a color, mood, or theme. Exports include CSS, SVG, and PNG; palette pages also provide copy options for colors, ShaderToy, and JSON.

Unauthenticated GET endpoints provide palette JSON, search, ranked lists, and PNG renders without an API key. A URL seed determines a palette, so the same seed reproduces the same colors. Generated and exported gradients may be used in lawful personal and commercial projects under a perpetual, royalty-free license. Some features require an account, available through Google OAuth or email magic links. Documented API and image reads are limited to 300 requests per 10 seconds per IP, and PNG dimensions are capped at 2400 pixels per side and about 3 megapixels total. Grabient recommends the tool for UI palettes, gradients, and backgrounds, not accessibility contrast checks, image palette extraction, exact brand-hex matching, or print and CMYK work.
