Croquet OS

Croquet is a software system for creating multiuser digital experiences on the web. It lets you build real-time multiuser apps without writing a single line of server code, or deploying or managing any servers. Croquet OS is available as a JavaScript library that synchronizes Croquet apps using Croquets globally deployed reflector servers and provides seamless cross-platform real-time interactivity to any user with a network connection and a web browser.

While Croquet itself is independent of any specific UI framework, we provide our own frameworks that build on top of it (see below).

Croquet Virtual DOM

The Croquet Virtual DOM is a high-level framework that extends the core capabilities of Croquet. It’s a set of tools for writing Croquet applications that use a browser’s DOM as multiuser interface elements. Yoshiki Ohshima gave a talk on Croquet and the live programming functionality built into the Virtual DOM Framework. The talk was in Japanese but you can turn on the English subtitles.
