Playroom

Playroom is a code-oriented design environment that renders JSX written against a team’s own component library. It shows designs across several themes and screen sizes at once, and its README describes it as a zero-install environment.

Playroom runs as a local development server while a design system is being worked on. For publishing, it builds into a standalone bundle that the README says can be deployed next to existing design system documentation. It is installed as the npm package named in the README, and the repository is a pnpm workspace whose public package is Playroom itself.
