Get the tools
Developers feel right at home and productive in the Ubuntu SDK IDE, whatever their experience.
This integrated development environment offers a richly featured and deeply integrated set of development tools that gears up productivity and includes direct access to attached Ubuntu devices and Ubuntu emulators.
Pick your language
For the UI, you can choose either QML or HTML5 to write Ubuntu apps.
For the logic, JavaScript, Qt and other languages such as Python or Go can power refined QML UIs.
