An application framework may be developed to support rendering of features on application web pages. Feature codes of features and associated content code that are developed as Representational State Transfer (REST)ful web services using a variety of different programming languages are received and stored in a Feature as a Service (FaaS) data store. The RESTful web services of the feature codes and the content codes are callable by the application server via the application framework. Content for populating the features are stored in a content data store. Application code is generated to provide application web page code for an application web page that includes one or more features. The application code is configured to cause the application server to access, via the application framework, a RESTful web service to obtain a feature code of a feature and access another RESTful web service to obtain specific content that populates the feature.
