Ionic is an open-source SDK for developing hybrid mobile app developed from three minds of Max Lynch, Ben Sperry and Adam Bradley in 2013. The original version was first launched in 2013 and built on top of AngularJS and Apache Cordova. The latest version was re-built as a set of Web Components, allowing users to choose any UI framework like Angular, React or Vue.js. It also permits the use of Ionic components with a non-UI framework. The main factor of Ionic is providing tools and services for developing hybrid mobile, desktop and Web apps based on modern web development technologies and practices, using Web technologies like CSS, HTML5, and Sass. Mobile apps can be built with these Web technologies and allowed through native app stores to be installed on devices by utilizing Cordova or Capacitor.
