KeystoneJS is a content management system and framework to build server applications that interact with a database. It is based on the Express framework for Node.js and uses MongoDB for data storage. It represents a CMS alternative for web developers who want to build a data-driven website but don’t want to get into the PHP platform or large systems like WordPress.
