APS vs Revit API

A practical way to choose between APS services and in-product Revit API automation.

When deciding between APS and the Revit API, the best choice usually depends on where the workflow should run and who needs access.

Practical comparison

Use Revit API when automation must run inside Revit and directly manipulate model elements in the authoring environment.
Use APS when you need cloud processing, integrations, viewer workflows, or cross-system orchestration.
In many teams, the pattern is hybrid: Revit API for authoring-time tasks, APS for distribution and external access.

The key is to optimize for maintainability and deployment constraints, not just technical preference.
