Web App Runtime

Amazon's web app runtime is built on the open-source Chromium project. It is GPU-accelerated and optimized for fluid performance on Kindle Fire. The runtime supports the latest HTML5 features and includes standards-based extensions that give you access to offline storage and location sensors. With the web app runtime, your web apps can achieve fluidity and speed approaching that of native apps.
