Storybook
The storybook package contains Storybook's core. It includes:
Storybook's CLI and development server
Storybook's main UI (aka "the manager")
Core functionality including component controls, toolbar controls, action logging, viewport control, and interaction debugger
User-facing utility libraries such as storybook/test, theming, and viewport
Libraries used by Storybook's ecosystem of frameworks, addons, and builders
It also contains a variety of other libraries and utilities under the stroybook/internal namespace, such as utilities for CSF, MDX & Docs.
React Styleguidist is a component development environment with a hot-reloaded dev server. It's similar to Storybook but focuses more on living style guides, and it uses Markdown for documentation.
Docz leverages MDX to bring Markdown and JSX together into one file, enabling easier documentation writing for your components. It's simpler to set up than Storybook but might not be as feature-rich.
Playroom allows you to simultaneously design across a variety of themes and screen sizes, powered by JSX and your own component library. It's different from Storybook in that it focuses on layout and design rather than component isolation.
