PlanetScale is a cloud database company providing managed hosting for Vitess, sharded Postgres through its Neki architecture, and standard PostgreSQL. Its platform is built for speed, reliability, and workloads that exceed the capacity of a single database node. For MySQL, Vitess enables horizontal scaling through sharding; Neki brings a next-generation sharding design to large Postgres workloads. Both support scale-focused database operations, including online schema changes and connection pooling.

PlanetScale offers fully managed Postgres clusters on AWS and GCP, with high-availability options, automated failover, backups, read replicas, and branch-based development workflows. Its PlanetScale Metal service uses NVMe-backed infrastructure to deliver high performance and unlimited IOPS. Additional capabilities include traffic controls for managing query budgets, online upgrades, cluster resizing, and resharding. Customers can choose among deployment options, including bring-your-own-cloud through PlanetScale Managed, to address security and compliance needs. The company serves demanding database workloads, with customers including organizations running Vitess and Postgres at large scale. PlanetScale also provides documentation, quickstarts, migration resources, pricing information, and support for teams adopting its database services.
