Serverless MySQL-compatible database platform powered by Vitess, offering non-blocking schema changes and horizontal autoscaling.

About PlanetScale

PlanetScale is an advanced serverless database platform engineered on top of Vitess, the battle-tested horizontal scaling technology originally created at YouTube. Designed to provide hyper-scalable relational data storage without the complexity of manual database sharding, PlanetScale delivers predictable query performance and massive throughput for high-growth applications.

The platform introduces Git-like database branching, enabling software developers to test schema migrations in isolated development branches before merging them into production. PlanetScale executes zero-downtime, non-blocking schema migrations automatically, eliminating table locks and performance degradation that traditionally plague production MySQL database alterations.

PlanetScale operates as a fully managed cloud service on AWS and Google Cloud infrastructure, providing automated connection pooling, query insights, and automated daily backups. Following trial evaluations, PlanetScale offers tiered usage-based subscriptions and dedicated single-tenant enterprise clusters.
