What is Estuary?
Estuary is a data movement platform that combines change data capture, streaming and batch ETL in one product. Its site describes log-based CDC, SaaS and batch pipelines unified in an event-driven ETL architecture, from a first table to petabyte scale. The company lists more than 200 connectors, and its documentation says a first pipeline can be set up in 15 minutes.
The product covers log-based replication from databases, streaming changes to any destination, and scheduled loads from SaaS apps and files. Users can manage pipelines from the terminal with the flowctl command line tool, and the documentation includes a guide for letting AI agents build and run pipelines. Pricing follows the data you move and the connectors you run: each active source or destination is one connector instance, prorated by the hour, and you can start free, scale month to month or choose an annual plan with volume discounts. Source code is public on GitHub under estuary/flow.
