PlanetScale vs Cassandra: 2026 Comparison

PlanetScale and Cassandra serve different scaling models and team profiles. PlanetScale handles rapid prototyping and SQL workloads with managed infrastructure. Cassandra offers distributed resilience for high-write, multi-region systems but demands operational complexity. Choose PlanetScale if you want zero DevOps overhead; choose Cassandra if your scale justifies the learning curve. See the [comparison](/compare) for dimension scores.

Decision notes

Start with PlanetScale if you're validating a product, prototyping quickly or running a cash-constrained startup. Switch to Cassandra only when MySQL hits hard scaling walls—millions of writes/sec or sub-millisecond latency requirements. Most teams never need Cassandra. Test both in your environment; benchmark before choosing. [Startup ideas](/resources/startup-ideas) often start on PlanetScale and outgrow it.
