Ant Design theme editor

React components with the styles generated at runtime: no stylesheet to import, a theme object instead. UISandbox builds Ant Design 6.6.1 from its own package and opens it in the editor: seven screens in Ant Design's own components and its own defaults. Turn the brand, the type, the spacing and the corners, and every component follows. Nothing to install, nothing uploaded.

Ant Design in the UISandbox editor: the knobs on the left, Ant Design's own components on the right — Ant Design as it ships, in the editor. A real screenshot.

What you take with you

Export writes Ant Design's design system in Ant Design's own names, starting from what you see:

antd.theme.ts: the theme object Ant Design reads, since it has no stylesheet to edit
theme.css: the variables, in Ant Design's own names, as the knobs left them
install.md: where each file goes, step by step
MANIFEST.md: what could not be done, said rather than substituted
DESIGN.md: the design system for people and agents: colours, type, spacing, what each is for
.claude/skills/design-system/SKILL.md: for Claude Code, Cursor or Codex: build the next screen in Ant Design's own classes
tokens.json: W3C design tokens, which Tokens Studio and Figma variables import

On your own app

If your app runs on Ant Design, the sandbox recognises it from the rendered page and writes the design system in Ant Design's names from your app's own values. What you turned on the kit comes with you. The quickest way in is the one where nothing leaves your machine: run npx uisandbox-mcp open in your project, or ask your agent to "open this app in UISandbox". How it works.
