ColorKit vs Grabient

ColorKit is a free web toolkit for designers and artists working with color palettes, gradients, and other design elements. Its palette generator offers AI prompts, style modes, color locking, and controls for hue, brightness, saturation, and temperature. Palettes can be exported as PNG, copied as CSV or an array, or shared by URL. The image palette tool extracts 2 to 10 colors, allows manual adjustment of color points, and can create a PNG collage; ColorKit says images used by this tool are never uploaded to its server. The gradient maker supports linear, radial, and conic gradients, adjustable color stops, AI generation, CSS copying, and image or code export, with up to eight stops per gradient. A contrast checker calculates text and background contrast ratios and can pick colors from an uploaded image or image URL. Other listed tools include a color picker, shade generator, SVG color changer, background maker, and color mixer. ColorKit is available on the web. Image palette extraction needs no signup; a free account is required to save palettes and gradients.

Grabient is a free web-based tool for making CSS gradients and managing palettes. Users can adjust gradient style, angle and steps, then create, save, browse, manage or like palettes. Search accepts descriptive terms such as colors, moods or themes. Exports include CSS, SVG and PNG; palette pages also offer copy options for colors, ShaderToy and JSON. Unauthenticated GET endpoints provide palette JSON, search, ranked palette lists and PNG renders without an API key. A URL seed determines a palette, so repeating the same seed reproduces its colors. Generated or exported gradients may be used for lawful personal and commercial projects under a perpetual, royalty-free license. Some features require an account, available through Google OAuth or email magic links. The documented API and image reads are limited to 300 requests per 10 seconds per IP, and PNG output has size caps. Grabient recommends itself for UI palettes, gradients and backgrounds, not accessibility contrast checks, image palette extraction, exact brand-hex matching or print/CMYK work.
