What does Estuary do?

Estuary is a real-time data platform that moves information between databases, data warehouses, and AI systems. It handles both streaming data and batch processing through a single interface, allowing teams to build data pipelines that keep information flowing continuously. The platform focuses on low latency, with data delivery typically happening in under 100 milliseconds, while maintaining high reliability with 99.9% uptime.

What makes Estuary stand out is its unified approach to data movement. Instead of needing separate tools for streaming and batch ETL, users can manage both through one platform. It uses change data capture technology to automatically detect and propagate database changes, and includes built-in connectors for popular systems like Snowflake, Kafka, and various databases. The service is fully managed, meaning users don't need to worry about infrastructure maintenance.

Data engineers and developers benefit most from Estuary when they need to build reliable data pipelines quickly. Real-world applications include feeding real-time customer data to analytics dashboards, keeping data warehouses synchronized with operational databases, and providing fresh training data to machine learning models. Companies in finance, e-commerce, and healthcare use it to ensure their data flows reliably between systems without manual intervention.
