ColorDesigner vs Grabient

ColorDesigner is a web and extension platform for creating color wheels, palettes, and gradients. Its listed 13 tools include a palette builder, gradient generator, color mixer, color wheel, converter, image palette extraction, image color picking, contrast checker, and color comparison. The palette builder creates tints, shades, tones, and complementary, analogous, split-complementary, triadic, and tetradic harmonies. The Free plan costs nothing and includes 12 tools, HEX export, up to five saved colors, five palettes, and one project. Pro is $37.20 a year, billed annually, excluding tax; it adds unlimited saved colors, palettes, and projects, plus export in HEX, RGB, HSL, LAB, LCH, OKLAB, and OKLCH. Subscription plans include a 14-day free trial; the one-time payment option has no trial. The Figma plugin creates tints, shades, harmonies, and stepped gradients from selected layers or local styles, but supports solid fills only. The Photoshop extension includes a color wheel, OKLCH support, harmonies, and stepped gradients with hue interpolation across color spaces.

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.
