Component System

Component system designed for scale

Move fast with a carefully crafted component system built to grow with your product. Easy to use and customize.

  • Semantic tokens. Our token system gives you intelligent design decisions out of the box—colors, spacing, and sizing that work together harmoniously while remaining easy to customize for your brand.

  • Recipes. Pre-built component variants and compositions that let developers quickly assemble complex UI patterns without wrestling with CSS or design decisions.

import { defineSemanticTokens } from '@saas-ui/react'

export const semanticColors = defineSemanticTokens.colors({
  status: {
    success: {
      value: { _light: '{colors.green.500}', _dark: '{colors.green.500}' },
    },
    error: {
      value: { _light: '{colors.red.500}', _dark: '{colors.red.500}' },
    },
    warning: {

“At Aidbase, we're developing a framework-agnostic component library to support our various chatbots, ticket forms, and other widgets. It's challenging building something that's a great developer experience and performing well at the same time. SaaS UI has been a massive help in this.”

“In order to be able to build beautiful portals in an efficient way, we were we looking for a turnkey solution, with enough flexibility. SaaS UI is exactly what we were looking for. Eelco is very thoughtful. We had factored in that early adopting comes with some risk - but so far all any issues are quickly remedied and there are almost weekly new useful features for us!”

“The SaaS UI was key to building my SaaS platform on NextJS. It allowed me to create my platform's UI quickly and easily, with many pre-made components that saved me a lot of development time. Also, the SaaS UI is very flexible and can be easily customized to suit my specific needs.”

Jacob Leuthardt

Founder - Frantic Software

“SaaS UI has let my business hit the ground running. Good UI is the foundation of good software and SaaS UI is what makes good software. Before SaaS UI, my UI was hand written in plain HTML/CSS/JS. Now it's an eye-catching experience that turns heads.”
