PlanetScale is a cloud-native database platform designed to help developers build, scale, and manage relational databases without the complexity of traditional infrastructure. It provides fully managed MySQL-compatible (via Vitess) and Postgres databases with a strong focus on performance, scalability, and developer experience.

The platform solves common challenges in database management such as scaling, downtime during schema changes, and operational overhead. Instead of manually managing database servers, replication, and failover systems, PlanetScale automates these processes with features like high-availability clusters, automatic failover, connection pooling, and global distribution.

A key innovation in PlanetScale is its branching workflow, which allows developers to create isolated database branches for development and testing—similar to Git workflows. This enables safe schema changes without downtime, as changes can be tested and merged into production through deploy requests.

PlanetScale is built on Vitess, a database scaling system originally developed at YouTube to handle massive MySQL workloads. This enables horizontal sharding and virtually unlimited scalability while abstracting complexity away from developers.

The platform also includes performance monitoring tools, query insights, and integrations with modern data pipelines, making it suitable for both startups and large-scale production systems. It is widely used for applications that require high availability, fast query performance, and the ability to scale seamlessly as data grows.

Key features include:

• Fully managed MySQL-compatible (Vitess) and Postgres databases
• Horizontal scaling with sharding and high availability clusters
• Branching workflow for safe, zero-downtime schema changes
• Built-in connection pooling and automatic failover
• Query performance insights and observability tools

Common use cases include:

• Hosting production databases for web apps
• Scaling SaaS platforms
• Managing high-traffic applications
• Enabling zero-downtime deployments
• Supporting modern full-stack development workflows.

PlanetScale was founded in 2018 by the creators and maintainers of the Vitess project, a widely used database scaling system originally developed at YouTube.
