Estuary

Estuary is a real-time data integration platform that lets you sync, transform, and route data across systems with ease. It unifies ETL, streaming, and batch pipelines into a single, scalable solution for modern data workflows.

Estuary is a powerful real-time data integration platform designed to simplify and accelerate how organizations move and process data across their ecosystems. Built for the demands of modern data workflows, Estuary unifies batch and streaming data pipelines into a single, cohesive platform, eliminating the need for multiple disparate tools.

At its core, Estuary Flow enables users to seamlessly capture data from a wide range of sourcesโ€”including databases, SaaS applications, event streams, and cloud storageโ€”and deliver it in real time to destinations like data warehouses, data lakes, analytics platforms, and custom applications. Whether itโ€™s syncing data from PostgreSQL to Snowflake, Kafka to Apache Iceberg, or MongoDB to BigQuery, Estuary handles the complexity with built-in connectors and scalable infrastructure.

What sets Estuary apart is its ability to process change data capture (CDC), stream transformations, and schema enforcement without sacrificing speed or reliability. Users can define complex data flows via a visual interface or YAML-based configuration, and the system automatically manages versioning, backfills, schema evolution, and recovery.

Estuary Flow also offers unique features like time travel, declarative derivations (SQL-based data transformations), and strong guarantees around data consistency and fault tolerance. It supports private deployment and Bring Your Own Cloud (BYOC) models for teams with compliance or security needs, and integrates with tools like dbt, Prometheus, and Kafka clients through its open interfaces.

By bridging the gap between traditional ETL and real-time streaming, Estuary empowers data engineers, analysts, and developers to build resilient pipelines that keep data fresh, trustworthy, and actionableโ€”fueling analytics, AI, and operational workloads without the overhead of managing multiple tools.

A startup from New York, the United States that is founded by David Yaffe, Johnny Graettinger.
