Microsoft Power Apps offers low-code solutions for designing custom applications that support the automation of processes and the development of smarter working solutions.
The original focus on Canvas and Model-driven apps remains, but the Power Apps ecosystem has expanded to include external-facing web experiences in its own right.
What Is A Canvas App? Delivering Traditional Functionality Faster
Canvas apps are comparable to traditional mobile or tablet apps in terms of user experience, deployment and integration capabilities. Instead of writing traditional code, makers visually design and create apps by dragging and dropping components onto a blank canvas. They can connect to a wide range of data sources, including databases and cloud services, and offer rich functionality such as forms, galleries and interactive elements. Canvas apps are highly customisable, allowing organisations to tailor layouts and workflows to specific business needs.
Benefits of Canvas Power Apps
-
Highly tailored user experience
-
Drag-and-drop design environment
-
Excel-style business logic expressions
-
Deployable on mobile devices, web and embedded environments (Teams, SharePoint, Power BI)
-
Offline capabilities and advanced features
What Is A Model-driven App? Supporting Joined-up Working
Model-driven apps are data-centric applications built on Microsoft Dataverse and other enterprise data services. They are ideal for structured business processes where data integrity, consistent UI and automated flows are essential. Pre-built components such as forms, views and dashboards dynamically adapt to the underlying data model. Organisations can define complex business logic, enforce security roles and automate process flows with minimal coding. They also offer both online and offline functionality for working through changing circumstances or patchy connectivity.
Benefits of Model-driven Power Apps:
- Unified Interface: Seamless integration with Dynamics 365.
- No-code design: Focus on components without needing to code.
- Integrated business process flows: Ensure consistent business processes.
- Leverage Dataverse: Use the potent data platform to your advantage.
Power Pages: A Third App Category for External Engagement
Power Pages (formerly Power Apps Portals) is now recognised as a standalone category in the Power Apps ecosystem. It enables organisations to create secure, customisable external-facing websites that interact with Dataverse data without exposing back-end systems directly.
Typical use cases include customer service portals, partner self-service sites and vendor collaboration platforms. This extends Power Apps beyond internal users to wider stakeholder groups, increasing the strategic impact of low-code solutions across the enterprise.
Clear Use-Cases and Industry Examples
Understanding the types of Power Apps excels helps align technology to business problems:
-
Canvas — bespoke front-line operational tools such as timesheet apps, equipment checks, field service data capture or custom forms.
-
Model-driven — complex data management scenarios such as CRM systems, case management platforms or process-governed workflows.
-
Power Pages — customer service portals, partner access and self-service interfaces driven off the core business data model for external audiences.
Comparing Pros and Cons: Decision-Aid Table
| Feature / Area | Canvas Apps | Model-driven Apps | Power Pages |
|---|---|---|---|
| Best Fit | Highly custom UI processes | Structured enterprise processes | External-facing interactions |
| Customisation | Excellent | Moderate | Moderate with web design focus |
| Development Model | Drag-and-drop | Data-model first | Web template and Dataverse |
| Data Source | Multiple connectors | Dataverse | Dataverse |
| External Access | Limited | Internal users | Designed for external users |
| Licensing Implications* | Per app/user plans | Per user plans | Per login/anonymous |

Canvas vs. Model-driven: When To Consider Each
If user experience and custom look-and-feel are central, Canvas apps are generally the best choice.
Where consistent data handling and business process automation matter more, Model-driven apps deliver structured, governed environments.
Power Pages is the preferred route when the solution must be exposed outside the organisation and securely interact with internal business data.
What Types Of Power Apps Are Best For You?
Microsoft's Power Platform has significantly simplified the app development process, making it more accessible to a broader range of users.
Whether you opt for Canvas or Model-driven apps largely depends on your specific business needs and the problem you're trying to solve. By understanding the core features and benefits of each, you're better equipped to make an informed choice and leverage Power Platform to its fullest.
