YugabyteDB Documentation

Distributed PostgreSQL for Modern Apps

YugabyteDB is a cloud-native distributed PostgreSQL-compatible database that combines strong consistency with ultra-resilience, seamless scalability, geo-distribution, and highly flexible data locality to deliver business-critical, transactional applications.

Available as a flexible service and with a uniform experience across Kubernetes and/or any combination of public, private, or hybrid cloud, YugabyteDB provides distributed PostgreSQL that scales and never fails.

YugabyteDB provides PostgreSQL without limits and is an excellent fit for new or modernized transactional applications that need absolute data correctness and require scalability, high availability, or global deployment.
