Web widgets are reusable, stand-alone Web applications that can be embedded into third-party sites by any user that has appropriate rights of authorship. They don’t require site-specific compiling or giving control of the site to the party providing the widget. Widgets use representational state transfer (REST)-based APIs to communicate with Web-accessible resources.
