In-application dynamic user interface rendering

A system comprising:

• a computing server comprising one or more processors and memory storing computer code comprising instructions, wherein the instructions, when executed by the one or more processors, cause the one or more processors to:
• receive, from an application operator, a design of an in-application user interface (UI) for display by a software application owned by the application operator;
• receive, from the application operator, a trigger condition for displaying the in-application UI;
• and
• compile the design to a payload that includes (1) one or more UI objects that define the in-application user interface and (2) parameters of the UI objects;
• and
• a software development kit (SDK) incorporated in the software application as part of the software application, the software application developed by the application operator, and the SDK in communication with the computing server, wherein the SDK is configured to:
• monitor an event associated with a computing device at which the software application is installed, wherein the event meets the trigger condition for displaying the in-application UI;
• transmit a message related to the event to the computing server;
• receive, subsequent to the message, the payload from the computing server;
• and
• cause the software application to render, based on the payload, the in-application UI in a native code of the software application.
