What is shadcn/ui?
shadcn/ui is turning a component registry into infrastructure for AI app UIs.
shadcn/ui has stopped being just a Radix-based component registry. It now supports three primitive bases - Radix, Base UI (the default since July) and React Aria - and has been shipping registry infrastructure of its own: GitHub-repo registries in June, server-side search in July. The newest work sits outside components entirely, in @shadcn/helpers, a utility package aimed at AI SDK and TanStack AI.
What is Zeroheight?
Design system documentation making itself the constraint on AI-generated UI
Three releases in February, each recorded twice. An AI Assistant embedded in SSO-protected styleguides lets viewers chat with the guidelines to find tokens and guidance. The same Assistant became available inside Slack and Microsoft Teams via mention. And a Figma-verified connector for Figma Make brings documented design system guidance into AI-powered prototyping.

shadcn/ui is turning a component registry into infrastructure for AI app UIs.
◆ Current state
shadcn/ui has stopped being just a Radix-based component registry. It now supports three primitive bases - Radix, Base UI (the default since July) and React Aria - and has been shipping registry infrastructure of its own: GitHub-repo registries in June, server-side search in July. The newest work sits outside components entirely, in @shadcn/helpers, a utility package aimed at AI SDK and TanStack AI.
◆ Where it's heading
Two arcs run in parallel. One is decoupling from any single primitive vendor, which turns the registry into a distribution layer rather than a wrapper around Radix. The other is a push up the stack into AI application code - chat interface components in June, typeset for streaming text in July, and now mocks for paused tool calls and approvals. The components are becoming a means to a larger surface.
◆ Prediction
Expect the helpers line to keep extending along agent-workflow states - the entries so far move from introduction, to chat surfaces, to human-in-the-loop - and more composite patterns like Questionnaire rather than new primitives.

Design system documentation making itself the constraint on AI-generated UI
◆ Current state
Three releases in February, each recorded twice. An AI Assistant embedded in SSO-protected styleguides lets viewers chat with the guidelines to find tokens and guidance. The same Assistant became available inside Slack and Microsoft Teams via mention. And a Figma-verified connector for Figma Make brings documented design system guidance into AI-powered prototyping.
◆ Where it's heading
zeroheight's problem has always been that documentation nobody opens does not govern anything. All three releases attack that from different sides: bring the docs to where people already are (Slack, Teams), let them be asked instead of read (Assistant), and inject them into the tool that generates UI (Figma Make). The last is the most consequential, because it changes documentation from a reference into an input.
◆ Prediction
Expect connectors for further AI generation surfaces beyond Figma Make, since the Figma Make integration establishes the pattern of design system guidance as generation context rather than as a page someone consults.
