👋 Hello Developers!
If you're exploring the world of Power Apps, you’ve probably come across two popular types of apps — Canvas apps and Model-driven apps. But what exactly is the difference between the two? And more importantly, which one should you use for your next project?
As someone who has worked with both types extensively in real-world business scenarios, I wanted to share a simple, clear comparison — the kind of explanation we all wish we had when starting out.
Let’s get right into it.
🔍 What is a Canvas App?
A Canvas app gives you a blank layout where you have full control over the user interface. You can drag and drop controls like buttons, galleries, and forms wherever you want — very much like designing a PowerPoint slide.
🎯 Key Highlights:
-
Design-first approach: You start by designing the UI.
-
Custom layout: Choose screen size and orientation (phone, tablet, etc.)
-
Multiple data sources: Connect to SharePoint, Excel, SQL, Dataverse, and more.
-
High UI flexibility: Ideal for building user-friendly, tailored interfaces.
✅ Best suited for:
-
Simple apps that need a strong user experience (e.g., time entry, leave request)
-
Mobile-first or tablet-friendly apps
-
Use cases involving data from multiple sources
🔍 What is a Model-driven App?
A Model-driven app is built around your data model. You define your data tables, relationships, business logic, and Power Apps automatically generates a responsive UI based on that structure.
🎯 Key Highlights:
-
Data-first approach: You design the data model and logic first.
-
Built on Dataverse: You must use Microsoft Dataverse as the backend.
-
Standard UI: UI is generated automatically, based on your data.
-
Includes business processes: Add rules, flows, and security roles.
✅ Best suited for:
-
Complex business scenarios (e.g., case management, customer service apps)
-
Enterprise-grade apps needing structured workflows
-
Scenarios where governance and data relationships are important
🆚 Canvas vs Model-driven – Side-by-side Comparison
| Feature | Canvas App | Model-driven App |
|---|---|---|
| Approach | Design-first | Data-first |
| UI Flexibility | High – Full control over layout | Limited – Auto-generated |
| Backend options | Multiple data sources supported | Only Dataverse |
| Custom logic | Power Fx formulas | Business rules, workflows, plugins |
| Learning curve | Easier for beginners | Slightly steeper |
| Use case examples | Expense tracker, Leave request | CRM, Case Management |
💡 Real-World Analogy
Think of a Canvas app like creating a custom-designed flyer — you decide how every piece looks.
Whereas a Model-driven app is more like a structured enterprise portal — it follows standards, processes, and templates.
🙋 When Should You Use What?
Here’s a simple rule I follow:
🧠 If you want full control over the UI and user experience, go with Canvas. If your app needs structured business logic, workflows, and relationships — choose Model-driven.
Also, with recent updates, you can even combine both by embedding custom canvas pages inside model-driven apps — a great way to get the best of both worlds!
🎁 Final Thoughts
Both Canvas and Model-driven apps have their strengths. There’s no “one size fits all” — it really depends on your business requirements, data complexity, and user needs.
If you’re new to Power Apps, try building a simple Canvas app first to get a feel for it. Then move on to Model-driven apps as your use cases grow.
