PlanetScale

PlanetScale is a serverless database platform built on MySQL that brings modern developer workflows and massive scalability to one of the world's most popular databases. Databases are often the hardest part of an application to scale and the riskiest to change, since schema modifications can cause downtime or data issues. PlanetScale addresses both challenges, offering a database that scales effortlessly and introducing a branching workflow — borrowed from how developers use version control for code — that makes changing your database schema safe, reviewable, and free of downtime.

The platform's signature feature is database branching: just as developers create branches to work on code changes safely, PlanetScale lets them branch the database to develop and test schema changes in isolation, then merge them into production with safe, non-blocking deployments. This brings a familiar, safe workflow to a part of development that has long been fraught with risk. Built on technology proven at enormous scale, PlanetScale also delivers the horizontal scalability needed for demanding applications, along with the reliability, performance, and developer-friendly tooling that modern teams expect from their data layer.

PlanetScale is used by developers and teams that need a scalable, reliable database with workflows that fit modern development practices. The value is scalability plus safety: it removes the fear and risk traditionally associated with database changes and scaling, letting teams evolve their schema confidently and grow without hitting the usual database walls. For applications that need to handle significant load and for teams that want their database to support a fast, safe development workflow rather than being a bottleneck and a source of anxiety, PlanetScale offers a compelling modern solution. By applying the lessons of version control and large-scale infrastructure to MySQL, it makes working with a production database dramatically more pleasant and dependable.
