## What it is
Calypso is the JavaScript and REST API powered single-page web application that serves as the WordPress.com dashboard. It is built with React, Redux, and a lightweight Node.js/Express server, enabling reading, writing, and managing WordPress sites from one interface.

## Use cases
- manage multiple WordPress sites from one dashboard
- run the WordPress.com admin interface locally for development
- build a single-page app on top of the WordPress.com REST API
- contribute to WordPress.com front-end code
- study a large-scale React and Redux application
- customize or extend the WordPress.com publishing experience

## When to choose
- you want to develop against or contribute to the WordPress.com dashboard
- you need a reference architecture for a large React/Redux single-page application
- you are building tooling on top of the WordPress.com REST API

## When to avoid
- you only need a self-hosted WordPress site without WordPress.com integration
- you want a small lightweight CMS admin rather than a large monorepo
- you need a generic WordPress theme or plugin starter
