Service Studio is the visual development environment of the OutSystems Platform. You can use it to develop all aspects of your mobile and web apps. Service Studio includes a visual debugger, visual diff & merge (to combine the work of several developers into one fully integrated solution), 1-Click deployment and TrueChange (a full reference checking and self-healing engine). When you're applications are ready, you will need a server (in the cloud or on premises) to deploy and run them. Get yours at http://www.outsystems.com/get-started/
