Hi Michael Stoler,
Thanks for reaching out to Microsoft Q&A.
I don't think it is completely free there might be some minimal charges for the pipelines that you are creating, even though you don't run them.
Pricing for Data Pipeline is calculated based on:
- Pipeline orchestration and execution
- Data flow execution and debugging
- Number of Data Factory operations such as create pipelines and pipeline monitoring
What is an inactive pipeline and when is it charged?
- An inactive pipeline is one that is not associated with a trigger and that has zero runs within a month. A charge is incurred after one month of zero runs.
I would suggest you create an estimate of all your proposed monthly activity and try out how much does it arrive using the following pricing calculator.
