In some embodiments, a method receives a definition that associates a compiler with a content type. The definition defines blocks that can be included in the content type. The method receives an input to create the content type on a platform. A compiler is selected from a plurality of compilers based on the compiler being associated with the content type in the definition. Compilers use different technologies to generate content, and the platform allows the plurality of compilers to be used. The method receives a model for creating content for the content type and processes the model using the compiler to create output for blocks in the model. The output for the blocks is rendered to display the content on a user interface.
