UI Customization for ADK Apps

[regnard]

While the Web UI has been great for testing and proving out the AI agent features, I realized there should be an easier way to put a custom UI over the agents.

I've had 2 proof of concept projects and the application of a custom UI was not easy and not documented. Setting the variable web=False in the get_fast_api_app was not intuitive, in addition to adding the custom frontend files.

I was also searching for an easier method to integrate the chat interface in our application. Without debug features. Is there any mechanism?
