3. Company: appMobi

Framework/Tool: jqMobi

This framework was designed to enhance the efficiency and performance of HTML 5 hybrid and Web apps or the iOS and Android platforms. The framework was introduced in January and received some negative criticism from ReadWriteMobile readers for the bugs in the beta version, as well as how easy one could get confused between jQuery Mobile and jqMobi (the latter is actually a re-written version of jQuery for Mobiles, using a few concepts of Zepto.JS). But the 1.0 version had a lot of bug fixes made, and 60 APIs that helped with event support and such. Considering its enhancements, it is relatively lightweight and yet efficiently deals with large hurdles in the development ecosystem, such as deployment challenges faces with mobile Web apps, problems related to rendering on Android, HTML5 sound issues and the area of game development. The framework has a PhoneGap XDK to wrap HTML5 apps so they can be deployed in Google Play and the App Store.

4. Company: Brightcove

Framework/Tool: AppCloud

The App Cloud is a premium Web apps host that provides APIs designed to fill out HTML5's many device-specific gaps, such as those that crop up when attempting to access a tablet’s built-in camera, or location finders. BrightCove is actually an enterprise solution that considers itself a content-hosting platform which is free of cost until you get the opportunity to ship your app to Google Play or the App Store (you will then have to pay $15,000 to access the premium edition). Like Sencha, Brightcove too aims to be a complete one-stop solution for HTML5 development.
