Abstract: Technology is described for enabling development of a computer application using a cloud-based application development service. The method can include generating, using a design codebase generating service, a design codebase for the computer application, the design codebase defining a front-end and a back-end in a base programming language; selecting one or more target programming languages, the one or more target programming languages different than the base programming language; and generating, using a source code generating service, a first set of source code for the computer application in the one or more target programming languages from the design codebase.
