PhoneGap vs Telerik AppBuilder [EOL] comparison

PhoneGap is a free and open source framework that allows you to create mobile apps using standardized web APIs for the platforms you care about.

AppBuilder is an Integrated Cloud Environment (ICE) that eliminates the complexity associated with cross-platform mobile development. By combining the convenience of a local development environment with the power and flexibility of the cloud, AppBuilder lets you build cross-platform mobile apps. As a cloud-based development environment, AppBuilder abstracts away the platform dependencies, not the management and configuration of the development environment. By leveraging Apache Cordova and NativeScript open source frameworks for mobile development AppBuilder lets you use your existing skills in HTML, XML, CSS, JavaScript, LESS and TypeScript to build compelling applications for the most popular mobile platforms iOS, Android, and Windows Phone. The integrated device simulator and the companion apps enable you to rapidly iterate your ideas and see them the way they would look and feel without actually building and deploying the application to physical devices. AppBuilder has integrated device deployment, to move from a simulation to the real thing. As development continues, AppBuilder LiveSync synchronizes changes in the code editor with the AppBuilder device simulator and all connected devices so you can view them instantly without having to re-build the app.
