## What it is
Petal Components is an MIT-licensed library of shadcn-style HEEx UI components (buttons, modals, tables, forms, sidebars, chat) for Phoenix LiveView apps, built on Tailwind v4. It ships with a hosted MCP server that exposes component schemas to AI coding tools like Claude Code and Cursor so they generate idiomatic markup.

## Use cases
- add prebuilt ui components to a phoenix liveview app
- use shadcn-style components in elixir heex templates
- let claude code or cursor generate correct petal component markup via mcp
- build dashboards with sidebar, table, and modal components
- style phoenix forms and buttons with tailwind v4
- add accessible menus, tree views, and chat components to liveview

## When to choose
- you build Phoenix or LiveView apps and want composable, copyable UI primitives
- you use AI coding assistants and want them to emit correct component usage
- you want Tailwind v4 components without React or a JS build step

## When to avoid
- you use React, Vue, or another non-Elixir frontend stack
- your project is pinned to Tailwind 3 and you cannot upgrade
- you need a fully managed component product with paid support (consider Petal Pro instead)
