Mobile Application Developers, while able to produce amazing applications, are limited by the native browsers own limited functionality. Basic features available on desktop browsers are completely absent from mobile browsers. The ability to view source code, debug javascript, or even execute a javascript command from a console are all tools developers have come to expect while developing websites.

This is where Socketbug fills the gap! Socketbug is a Remote Debugging Utility built using Socket.IO. This means you can now use modern browsers ( both mobile and desktop ) to work together to allow you to remotely debug you mobile web applications.

The javascript library fixes browser & device bugs, and makes sure your video is even more compatible across different browser versions.
