What is the shell

The registry-shell is a generic Next.js viewer for component registries. Plug in a registry, get a docs site + component preview + accessibility inspector + test summary + shadcn-format JSON endpoints — out of the box.

Scintillar UI runs on the shell. So does your registry, if you want.

What it does for you

• Hosts docs — MDX files in your registry render as /docs/[slug].
• Previews components — interactive component demos with tab chrome (Install / Docs / A11y / Tests).
• Serves shadcn JSON — your public/r/{name}.json files are served at https://your-shell/r/{name}.json so consumers can shadcn add.
• Renders branding — title, logo, favicons, GitHub button, install command template — all driven by a single config.

What it doesn't do

• No component library of its own. Empty out of the box; you bring the components.
• No opinions about your CSS tokens, framework choice inside components, or doc structure beyond "MDX files in a folder."
• No database. Everything's filesystem-driven.

Where next

• Features — what you get at a glance.
• Connect a registry — wire the shell to your project in ~30 seconds.
