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.
AI wireframing tool closing the loop from prompt to design to code
Visily's dated update posts show a steady march up the fidelity ladder. March added code generation for designs, a Plan Mode for ideation ahead of AI generation, and unsupported font replacement on Figma imports. February brought Figma import itself and blur effects; January added Design Instructions for consistent output and a Deep Design mode. Earlier releases covered shadows, a browser capture overlay, an AI Content Filler and interactive dropdowns.

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.
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.

The arc runs from making generated designs look right to making them useful downstream. Design Instructions and Deep Design addressed consistency and polish; Figma import opened a migration path in; code generation opens an exit path out. Plan Mode is the interesting addition — separating intent from generation, rather than treating one prompt as the whole brief.
With import from Figma and export to code both in place, expect the round trip to tighten — keeping generated code and design in sync is the obvious unsolved half, though the entries do not describe work on it yet.
