Pigment CSS is a zero-runtime CSS-in-JS library from MUI that extracts colocated styles into separate CSS files at build time. It integrates with Next.js and Vite and supports theming via CSS variables.

Use cases

  • write css-in-js styles without runtime overhead
  • extract colocated styles to css files at build time
  • style react components with themeable css variables
  • use css-in-js with next.js app router and server components
  • use css-in-js with vite
  • create global styles and animation keyframes in javascript

When to choose

  • you want css-in-js ergonomics with zero runtime cost in a Next.js or Vite app
  • you are already in the MUI ecosystem and want its styling approach
  • you need static css extraction for server components

When to avoid

  • you need a maintained library - the project is on hold in alpha phase
  • your bundler is not Next.js or Vite
  • you need production stability and long-term support
  • you prefer plain CSS or a mature solution like Tailwind or vanilla-extract
