A useful comparison begins with your data and the task people need to complete. If those are unclear, comparing platform feature lists will mostly reveal which vendor writes the longest list.
Power Apps includes different application approaches. Microsoft's model-driven overview describes model-driven apps around data, components, and Dataverse. Canvas apps give the maker more control over layout and can use different data sources through connectors. Those distinctions matter when evaluating a workflow.
Begin with the existing systems
List the records the application needs and where they are maintained. Identify whether the app owns those records or presents information from another system. Include the permissions needed to read and change them.
Then build a small acceptance case. An approval app might display a request, show supporting information, capture a decision, and update the authoritative record. Test the full path and an access refusal.
If you already operate within Microsoft's environment, evaluate how the application fits the governance and support practices you use. Check the current licensing and connector requirements for the exact design. This article does not quote prices or assume that a particular connector is included.
Define what custom development would change
Custom development can give a team control over interfaces and behavior, with responsibility for implementation and operations. Specify which requirement needs that control. An unusual workflow, distribution need, integration, or data model is more informative than a general preference for flexibility.
Power Apps also has developer extensibility. Microsoft's developer introduction describes custom components and connectors. Avoid framing the choice as a simple split between code and no code.
For each option, ask how a new field or approval rule is introduced, tested, and released. Ask who supports the app when its original maker is unavailable. Evaluate export and migration with an actual artifact, not a broad ownership statement.
Compare the approaches using a purchase request
Imagine an internal purchase-request process. Staff select an item, attach a reason, and send it to the assigned approver. The approved request must reach the system that records the purchase.
For a Power Apps evaluation, examine how the chosen app type represents those records and how its connectors reach the destination. For a custom implementation, examine the data model, interface, integration code and operating services you would need to supply. In both cases, ask how the approver is identified and what prevents a repeated submission from creating another purchase request.
Model-driven and canvas approaches should also be evaluated on their own fit. A records-centered process may suit a component-based interface; a specialized task layout may need different control over the screen. These are design hypotheses to test with users, not a ranking of the approaches.
Then request a realistic revision: add a second approval condition and preserve the history of older requests. Have the future maintainer explain the change and the release steps. If the result depends on a connector, premium capability or another service, put its current terms into the decision record. This gives the comparison a concrete operating consequence.
Give every candidate the same check
Use identical synthetic records, user roles, and acceptance criteria. Record the resulting implementation, required services, recurring obligations, and unresolved constraints.
OBTO is another approach worth evaluating when you want an agent to work with application artifacts through MCP. We build it, and we would apply the same workflow test to it. The platform overview introduces the product; specific entitlements and controls need verification for your app.
A new approval rule is a useful final comparison. Have the person who will maintain the application explain the change in each candidate, including the licensing or connector decisions it introduces.
