Fivetran

Billed on monthly active rows, so the bill tracks how much source data changes rather than how much is stored or queried
Each connection follows its own cost curve, so total spend is hard to predict before running a pipeline
The free plan allows 500,000 monthly active rows, 3,500 activation rows and 5,000 model runs
Transformations are metered separately, from $0.01 per model run above 5,000 down to $0.002 above 100,000
A schema change upstream that touches many rows raises the bill without any change on the customer's side

Free tier limited to 3 stateful agents
Pro tier capped at 20 stateful agents
