Pick a data pipeline tool without the vendor calculator dance.

A data pipeline tool moves rows from a source system into a warehouse, lakehouse, or back into a SaaS destination. The category splits into ELT, orchestration, streaming, change-data-capture, and reverse-ETL. In 2026, the leading managed vendors charge $14–$48 per million monthly active rows; self-hosted options trade subscription cost for a loaded 0.5 FTE.Fivetran pricing - pulled 2026-06-21
