A method for rule-based composition of user interfaces involves obtaining a user identity (ID) of a user accessing an application using a user interface and obtaining a user interface (UI) state of the user interface. Based on the UI state and based on the user ID, a plurality of rule-based recipes are obtained. Each rule-based recipe specifies a UI content suitable for an interaction between the user and the user interface. The method further includes ranking each of the rule-based recipes of the plurality of rule-based recipes based on a likeliness that the rule-based recipe is suitable, given the UI state and the user ID, identifying, from the ranked plurality of rule-based recipes, a highest-ranked rule-based recipe, obtaining the UI content specified by the highest-ranked rule-based recipe, and updating the user interface with the UI content.
