What is Estuary Flow?

Estuary Flow is a unified data movement and transformation platform for the whole data team.

Flow synchronizes your systems – SaaS, databases, streaming, and more – around the same datasets, which it stores in the cloud and updates in milliseconds. It combines the easy cross-system integration of an ELT tool and a flexible streaming backbone, all while remaining aware of your data's complete history.


A few examples of what you can do with Flow:

  • Perform change data capture from MySQL tables into PostgreSQL or a cloud analytics warehouse like Snowflake or Databricks
  • Capture and organize your data from your SaaS vendors (like Hubspot or Facebook), into an Apache Iceberg lakehouse
  • Fetch, transform, and load logs from cloud delivery networks (CDNs) into Elasticsearch or BigQuery
  • Hydrate real-time analytics systems such as Tinybird or StarTree
  • Instrument real-time analytics over your business events, accessible from current tools like PostgreSQL or even Google Sheets

Under the hood, Flow comprises cloud-native streaming infrastructure, a powerful runtime for data processing, and an open-source ecosystem of pluggable connectors for integrating your existing data systems.
