Disclosure: I work on ETLMaestro, which orchestrates pipelines on both ADF and Fabric, so weigh that. Every number below is a public list price (East US, pay-as-you-go unless I say otherwise, checked October 2026), and the math is here so you can check it.

TL;DR: Per non-copy activity run, ADF and Fabric list prices are within 1% of each other. The difference is that Fabric needs a running capacity. If you’d buy capacity just for pipelines, ADF is cheaper at almost any volume. A reserved capacity you keep busy beats ADF by about 40% per run, and capacity you already pay for with room to spare makes orchestration close to free.

The per-run math

ADF: $1.00 per 1,000 orchestration runs on the Azure integration runtime.

Fabric: 0.0056 CU-hours per non-copy activity run.…
