App Checker vs Solution Checker: A Comparative Insight
While both App checker and Solution checker serve the same fundamental purpose, the scope and intensity change slightly. The table below gives a comparison of the two:
| App Checker | Solution Checker | |
| Scope | Checks a single app | Checks entire solutions |
| Output | Identifies app errors, delegation warnings, and accessibility barriers | Gives a comprehensive report of issues affecting solution’s reliability, maintainability, and performance |
| Use Case | Used when developing or updating a PowerApps application | Used when developing or updating solutions that span across PowerApps, Flows, and more |
Each of these tools comes in handy at different stages of your Power Platform journey. Whether it’s the application-level precision of the App checker or the wider, solution-centric scope of Solution checker, these are valuable assets to streamline your apps and solutions. For a prospective Microsoft Power Platform Functional Consultant, harnessing the power of these checking tools can pave the way for functional and efficient Power Platform solutions.
