Canvas Apps vs Model-Driven Apps: What’s the Difference?

Understanding the two ways to build apps with Power Apps.

One of the first things you’ll discover when working with Power Apps is that there are two ways to build an app: canvas apps and model-driven apps.

Both are part of Power Apps, but they are designed for different types of solutions.

The easiest way to understand the difference is this:

A canvas app starts with the user experience.

A model-driven app starts with the data.

Canvas apps

Canvas apps give you complete control over how your app looks and works. You decide where buttons go, how screens are arranged and how users move through the app.

This makes canvas apps ideal when the user experience is important or when you want to guide someone through a specific process.

Common examples include:

• Inspection apps
• Expense forms
• Visitor registration
• Leave requests
• Mobile apps for employees

Model-driven apps

Model-driven apps take a different approach.

Instead of designing every screen yourself, you start by creating your data model. You define your tables, relationships and business rules, and Power Apps automatically generates a complete business application around that data.

The result is a structured application that is excellent for managing records, forms and related information.

Common examples include:

• Case management
• Asset management
• Customer records
• Service requests
• Project management

Which one should you choose?

A question many beginners ask is:

Which one is better?

The answer is simple.

Neither.

The right choice depends on the problem you are trying to solve.

If the layout of the screens is important and you want full control over the user experience, a canvas app is usually the better choice.

If your application is mainly about managing business data with relationships, forms and records, a model-driven app is often the better fit.

Choosing the right type of app from the start will make your solution much easier to maintain as it grows.

What about Power Pages?

Sometimes people wonder if they should use a canvas app for external users.

In most cases, the answer is no.

If customers, partners or suppliers need access through a browser, Power Pages is usually the better option. It is designed for secure external websites and portals, while Power Apps is primarily intended for users inside your organization.

In short

• Canvas app: Full control over the look, feel and user experience.
• Model-driven app: Structured applications built around your business data.
• Power Pages: Secure websites and portals for external users.
