Calypso is the new WordPress.com front-end – a beautiful redesign of the WordPress dashboard using a single-page web application, powered by the WordPress.com REST API. Calypso is built for reading, writing, and managing all of your WordPress sites in one place.
It’s built with JavaScript – a very light node plus express server, React.js, Redux, wpcom.js, and many other wonderful libraries on the front-end.
You can read more about Calypso at developer.wordpress.com/calypso.
You can try out the user-side of Calypso on WordPress.com (a lot of the logged-in area is Calypso; if in doubt, view source), you can poke around the code here on GitHub, or you can install it and run it locally. The latter is the most fun.
