To make Firebase Studio truly unbeatable, I suggest focusing on two key features:

Offline Support or Enhanced Performance: As projects grow in size, the prototyper tends to slow down significantly. Introducing an offline version or optimizing the prototyper for better performance with large resources would greatly enhance the user experience.

Cross-Platform Conversion: After developing a web application, providing a seamless way to convert the same project—with the same structure—into Android and iOS apps would be incredibly valuable. This would streamline the development process and reduce duplication of effort.
