PlanetScale is a serverless MySQL database platform built on Vitess — the database technology that YouTube and Slack use to scale MySQL to billions of queries. PlanetScale provides the operational simplicity of serverless deployment with the horizontal scaling capability of Vitess sharding for applications that outgrow single MySQL instances. Database Branching is PlanetScale's distinctive developer feature — creating separate database branches for development, staging, and feature work that can be merged like Git branches. Schema changes in PlanetScale use non-blocking migrations — modifying table schemas without locking rows, avoiding the database downtime that schema changes traditionally require in high-traffic MySQL applications. AI capabilities include AI-powered query analysis — PlanetScale Insights identifies slow queries, suggests missing indexes, and provides query optimisation recommendations. Boost applies AI query caching — caching frequently executed query results automatically to reduce database load and improve response times. Connection pooling handles thousands of simultaneous connections without overwhelming MySQL connection limits — essential for serverless architectures where each function invocation opens a new database connection. PlanetScale's Vitess foundation enables horizontal sharding for truly massive MySQL scale — the path from single-instance MySQL to a sharded cluster without migrating to a different database engine. With customers including Square, GitHub, and Hubspot, PlanetScale validates for high-scale web application database requirements.
PlanetScale AI runs as ml platform software built around data and code workflows. Users typically start with a prompt, upload, or connected data source, and the underlying model handles the heavy lifting before returning a result you can refine or export. It's available on web, cli, and api.
The capabilities that matter most for teams evaluating PlanetScale AI.
Git-like schema change workflow creating separate environments for safe schema development — review and merge schema changes like code before production deployment.
Zero-downtime schema changes in high-traffic MySQL — modifying table structures without locking rows that would impact production traffic.
Slow query identification and index suggestions from query performance data — reducing the DBA expertise required to identify and fix database performance bottlenecks.
