Pokki is an application platform for creating desktop applications using HTML5, CSS3 and JavaScript. Pokki uses Chromium internally, meaning layout and rendering is powered by WebKit and JavaScript is powered by V8 – giving you the latest and greatest of HTML5.

Beyond the standard HTML5 features you are accustomed to, Pokki gives you a set special JavaScript APIs and events, a window for your application called a popup, and an invisible background window for notifications.

Pokki also takes care of all the “desktop” stuff you don’t want to think about, like memory management and installers, so you can focus purely on application development. Would you like to have Gmail on your desktop with instant notifications for new mail, quick account switching and a beautiful interface? Or stay notified and quickly access everything you love about Facebook, without having to open a browser? Pokki brings awesome apps to your desktop too!
