description: Astro-first components through a shadcn-compatible registry.

> Fulldev UI for Astro. The `@fulldev` registry in `components.json` points at `https://ui.full.dev/r/styles/{style}/{name}.json`; see [installation](/astro/docs/installation.md).

Fulldev UI is an Astro-first component set and shadcn-compatible registry.
It keeps the familiar install flow and public composition of shadcn where that
is useful, then adds a smaller set of content-oriented primitives built for
Astro sites.

## What it is

Components are shipped as source files through the shadcn CLI, so you own the
code you install. They are written with vanilla Astro components and semantic
theme tokens instead of framework-specific wrappers.

## What is different

Most shared primitives stay close to shadcn/ui so the API feels familiar.
Fulldev-specific components such as `Section`, `Logo`, `Price`, `Rating`, and
`Video` focus on content-heavy and marketing-style Astro interfaces.

## Start here
