Fivetran: Pricing, Features & Alternatives

Fivetran is the default managed ELT service: 700+ connectors that pull from your production databases and SaaS tools into Snowflake, BigQuery or Redshift, handling schema drift and incremental syncs for you. Billing is consumption-based on Monthly Active Rows (MAR) — rows inserted or updated in a month, with unchanged rows and the initial backfill excluded — so the bill tracks how much your data actually moves rather than how many connectors you run.
