Playroom is a zero-install, code-oriented design environment that lets teams design with JSX powered by their own React component library. It builds a standalone bundle that can be deployed alongside design system documentation, enabling simultaneous design across multiple themes and screen sizes.

Use cases

  • prototype UI with real React components in the browser
  • preview a design system component across multiple themes at once
  • test responsive layouts across different screen sizes simultaneously
  • create quick interactive mock-ups with production component code
  • share design iterations via URL
  • evaluate design system flexibility and component coverage

When to choose

  • you maintain a React-based design system and want a code-oriented playground
  • you need to validate components against multiple themes and breakpoints simultaneously
  • you want a lightweight, deployable alternative to heavyweight design tools for component work

When to avoid

  • your components are not React/JSX based
  • you need pixel-level visual design tools rather than code-driven prototyping
  • you need non-browser design workflows like print or native mobile design
