About Estuary

Estuary, previously known as Estuary Flow, is a data movement platform that puts change data capture, real-time streaming and scheduled batch loads under one roof. The vendor describes its approach as right-time data, meaning data is delivered as fast as each use case requires rather than at a fixed cadence.

Pipelines are built from captures, collections and materializations, and records can be transformed in flight using Python, SQL or TypeScript. The platform lists more than 200 connectors, including Snowflake, Apache Iceberg, NetSuite and Kafka, and adds tooling for feeding AI models and letting agents create pipelines. Estuary publishes comparisons against Fivetran, Airbyte, Confluent and Debezium.

Estuary is a commercial product, offered as a fully managed service on public cloud, as a private deployment, or in a bring-your-own-cloud setup so data stays inside the customer's network. A pricing page and documentation with quickstarts are available.
