VLLNT UI

v0.3.0 / MIT

Web and native UI for AI agents.
One design system. Platform-correct renderers.

313 stable React web components plus a source-only React Native catalog for AI apps. Both renderers publish machine-readable availability and contracts, so agents choose platform-correct source instead of scraping HTML.

Canary0.4.0-canary.927b45a

What's coming

  • Source-only React Native renderer and shared design contracts for the 0.4.0 canary track; stable Web installation remains unchanged.
  • Localized Native catalog discovery, dependency/capability comparison, and extensible React/React Native source tabs in a single component preview surface.
  • Preserve nested scrolling, reduced-motion behavior and sidebar keyboard focus in the affected Web components.
  • Forward explicit tab accessibility relationships and label/keyboard handlers without changing default tab navigation.
  • Emit JSON-LD graph documents and localized Native discovery metadata without advertising unpublished npm packages.

    v0.2.1

    Public API: ProgressCard now re-exported from @vllnt/ui — it shipped in 0.2.0's tarball but was missing from the barrel, so import { ProgressCard } from "@vllnt/ui" resolved to undefined.

Agent-first

Built so AI coding agents can use it directly.

Every component ships as a machine-readable JSON descriptor with name, version, stability, accessibility schema, usage examples, and prop definitions. Agents discover the registry through three surfaces.

/llms.txt

Concise index per the llmstxt.org spec - sections, links, descriptions.

Open

/llms-full.txt

Full registry context in one fetch - docs + per-component descriptors.

Open

/mcp

Streamable HTTP MCP server. Tools: search_components, get_component, list_categories.
