Canvas Apps

 What are Canvas Apps?

Canvas apps are low-code Power Platform applications that allow you to design custom, responsive user interfaces with a drag-and-drop editor, connecting to Dataverse and 900+ data sources (e.g., Dynamics 365, SharePoint, SQL) to deliver tailored business solutions. In Dynamics 365 CRM, canvas apps are used to create standalone apps, embedded components (e.g., dashboards in Sales), or mobile interfaces, leveraging Power Fx for logic and Power Automate for automation. They prioritize UI flexibility, enabling pixel-perfect designs compared to the structured UI of model-driven apps.
Key Characteristics:
  • Low-Code: Built using Power Apps Studio with minimal coding, reducing development time by 50–70% vs. traditional coding.
