Power Apps Canvas vs Model-Driven Apps

Power Apps provides both Canvas Apps and Model-Driven Apps, but they are designed for different application scenarios. Canvas Apps provide greater control over the user interface and are useful when organizations need highly customized experiences. Model-Driven Apps are centered around Dataverse and are well suited for structured, data-driven business applications.

Choosing between them depends on factors such as data model, user experience, business processes, security, development effort, and maintainability.
