Differences Between Canvas Apps and Model-Driven Apps in Power Apps

Introduction

Power Apps offers two primary ways to build applications: Canvas Apps and Model-Driven Apps. Both serve different purposes and have unique design approaches, functionalities, and use cases. Understanding the differences between these two app types is crucial for selecting the right one based on business needs.

In this guide, we will explore the differences, features, architecture, use cases, and step-by-step processes to create each type of app.

1. Overview of Canvas Apps vs. Model-Driven Apps

Feature	Canvas Apps	Model-Driven Apps
Design Approach	Custom, free-form UI design	Predefined, data-driven layout
Data Source	Connects to multiple sources (SharePoint, SQL, Excel, etc.)	Requires Dataverse as the backend
User Experience	Fully customizable UI	Standardized UI based on data
Business Logic	Power FX formulas and automation	Built-in business logic and workflows
Security Model	Controlled via Power Apps Studio	Uses Dataverse Security Roles
Development Complexity	Low (drag-and-drop elements)	Moderate (requires structured data modeling)
Best for	Custom applications with unique UI	Enterprise applications with structured processes

2. What are Canvas Apps?

2.1 Definition

Canvas Apps in Power Apps allow users to design their application layout freely, much like designing a slide in PowerPoint. Users can drag and drop UI elements, integrate various data sources, and customize workflows using Power FX formulas.

2.2 Key Features of Canvas Apps

✅ Custom UI Design – Users can arrange buttons, forms, galleries, and images anywhere.
✅ Multiple Data Connections – Supports SharePoint, SQL, Excel, OneDrive, Dataverse, REST APIs, and more.
✅ Flexible Logic – Uses Power FX for automation and calculations.
✅ Works on Mobile & Desktop – Fully responsive applications.

2.3 Steps to Create a Canvas App

Step 1: Open Power Apps Studio

Go to Power Apps.
Click Create > Canvas App from Blank.
Name the app and select Tablet or Mobile layout.

Step 2: Add Data Sources

Click Data on the left panel.
Click + Add data.
Select a data source (e.g., SharePoint, SQL, Excel).

Step 3: Design the UI

Drag and drop controls like Buttons, Text Fields, Galleries, and Forms.
Customize colors, fonts, and styles.
Use Power FX formulas, e.g.: Label1.Text = "Welcome " & User().FullName

Step 4: Save and Publish

Click File > Save.
Click Publish and Share the app with users.

💡 Tip: Use Canvas Apps when you need a highly customized UI and flexible data integration.

3. What are Model-Driven Apps?

3.1 Definition

Model-Driven Apps are data-driven applications where the UI and functionalities are automatically generated based on Dataverse data models. These apps follow a structured, process-oriented approach, making them ideal for enterprise solutions like CRM and ERP.

3.2 Key Features of Model-Driven Apps

✅ Predefined UI & Components – Forms, dashboards, and views are automatically created based on the data model.
✅ Built on Dataverse – Uses Dataverse tables (formerly CDS) for structured data storage.
✅ Advanced Business Logic – Supports workflows, automation, and AI insights.
✅ Role-Based Security – Controlled using Dataverse Security Roles.

3.3 Steps to Create a Model-Driven App

Step 1: Set Up Dataverse

Go to Power Apps.
Click Dataverse > Tables.
Create a New Table (e.g., Customers).
Add columns (e.g., Name, Email, Status).

Step 2: Create a Model-Driven App

Click Create > Model-Driven App.
Name the app and select a Dataverse Table.
Click Done to generate the app.

Step 3: Customize Forms and Views

Click Edit Forms to modify how users interact with records.
Click Edit Views to define list layouts.
Configure Dashboards and Charts for analytics.

Step 4: Publish and Share

Click Save & Publish.
Assign Security Roles to control access.

💡 Tip: Use Model-Driven Apps when you need a structured, enterprise-grade application with complex workflows and automation.

5. Choosing Between Canvas Apps and Model-Driven Apps

Use Case	Recommended App Type
Custom UI with Unique Branding	Canvas Apps
Enterprise Solutions (CRM, HR, Finance)	Model-Driven Apps
Multiple Data Sources (SharePoint, SQL, etc.)	Canvas Apps
Complex Workflows & Security Models	Model-Driven Apps
AI-Driven Insights and Dashboards	Model-Driven Apps
Quick Prototyping & Small Apps	Canvas Apps

6. Combining Canvas and Model-Driven Apps

For hybrid scenarios, organizations can combine Canvas Apps and Model-Driven Apps within the same environment.

Example Use Case:

Use a Canvas App for a custom UI to enter customer data.
Store the data in Dataverse.
Use a Model-Driven App for managing and analyzing customer data.

💡 Tip: Power Apps Portals can also be used for external user access, such as customer self-service portals.

Conclusion

Both Canvas Apps and Model-Driven Apps have unique advantages.

Choose Canvas Apps for flexibility, UI customization, and multi-source integration.
Choose Model-Driven Apps for enterprise solutions with structured workflows and security.
Consider combining both for a hybrid solution with a custom front-end and structured backend.
