About Planetscale
PlanetScale is a serverless MySQL-compatible database platform founded in 2018 by Jiten Vaidya and Nick Van Wiggeren, built on Vitess — the database clustering system developed at YouTube to scale MySQL to millions of queries per second. PlanetScale's killer feature is database branching: create database branches like Git branches, apply schema changes safely, and merge them to production with zero-downtime schema migrations. Traditional MySQL ALTER TABLE locks tables and causes downtime at scale — PlanetScale's non-blocking schema changes run in the background using shadow tables, enabling schema migrations on billion-row tables without affecting production traffic. PlanetScale's deploy requests (similar to pull requests) provide a review workflow for schema changes — teammates can review and approve DDL before it merges to production. PlanetScale's Boost feature adds a query-level caching layer that accelerates expensive aggregation queries up to 1000x with no application code changes. PlanetScale's branching and sharding (via Vitess horizontal sharding) make it the choice for high-growth startups anticipating viral scale — it powers Shopify, GitHub, YouTube (Vitess origin), Slack, and Square. PlanetScale's pricing controversy came in 2024 when it eliminated its free Hobby tier, triggering significant developer backlash and driving users to alternatives (Neon, Turso, Supabase). PlanetScale raised $165M and remains the premium MySQL-as-a-service platform for teams needing proven web-scale MySQL with developer-friendly branching workflows.
Frequently Asked Questions
What is database branching in PlanetScale?
PlanetScale database branches work like Git branches for your schema. Create a development branch from production, apply schema changes (ALTER TABLE, CREATE INDEX) safely using non-blocking migrations, test with real application code, then open a deploy request to merge the schema to production. PlanetScale runs a diff showing what changed and applies it live without locking tables or causing downtime. This makes schema evolution as reviewable and safe as code changes.
Did PlanetScale remove its free tier?
Yes — PlanetScale eliminated its Hobby free tier in April 2024, affecting thousands of developers using it for side projects and open-source work. The decision caused significant backlash. PlanetScale's cheapest plan starts at $39/month. This drove many developers to Neon (free tier with 0.5GB), Turso (free tier with 500 databases), or Supabase (free tier with 500MB). PlanetScale remains the premium MySQL branching platform but is no longer accessible for hobbyists.
PlanetScale vs Neon — which serverless database should I use?
PlanetScale for MySQL-dependent applications, teams needing Vitess-powered horizontal sharding for web scale, or established products using MySQL ORM ecosystems (Laravel, Rails, Django with MySQL). Neon for new Postgres-first projects wanting serverless branching with a generous free tier. Neon's scale-to-zero compute and branch preview environments (for ephemeral per-PR databases) make it the modern choice for new projects not locked into MySQL.
