Cobalt - An hybrid framework for mobiles

"Cobalt meets all our expectations. The mix of native and HTML/JS enables a smooth and responsive application with an easier maintenance. This framework seems to have no limits, even advanced features such as the family tree or the feed management which were slow with Phonegap, are fast. As far as we know, there is no better hybrid framework on the market"

Guillaume Languereau

CEO, FAMICITY

"Cobalt allowed us to quickly prototype our application on iOS and Android. This framework enabled us to share 60 to 70 % of the code between platforms, while keeping some native system features. This made possible to design an application with the look and feel of native apps while keeping the ease of the Web development."

Baptiste Jamin

CTO, YOOL
