Visit UpstashFeature Comparison
| Feature | PlanetScale | Upstash |
|---|---|---|
| Database Type | MySQL-compatible relational database built on Vitess with full SQL support | Redis (in-memory key-value store) and Kafka (event streaming) with REST API access |
| Scaling Approach | Horizontal scaling through Vitess sharding without application code changes, handles large relational datasets | Automatic scaling with global edge replication for low-latency access across regions |
| Schema Management | Git-like branching with deploy requests, non-blocking schema migrations with online DDL for zero-downtime changes | Schema-less key-value and message streaming; no schema migrations needed |
| Connection Model | Traditional database connections with built-in connection pooling and query caching | REST API for connectionless access, optimized for serverless and edge functions without persistent connections |
| Pricing Model | Tiered pricing based on storage, rows read, and rows written; free tier includes 5GB storage and 1 billion row reads | True pay-per-request pricing with no idle costs; charges only for actual requests and data transfer |
| Best Use Cases | Relational data with complex queries, transactions, and relationships; applications needing SQL compatibility and ACID guarantees | Caching, session storage, rate limiting, real-time data, and event streaming in serverless/edge environments |
Pricing Comparison
Both platforms offer generous free tiers starting at $0/month, but with different pricing philosophies. PlanetScale uses tiered pricing based on usage metrics like rows read/written, while Upstash offers true pay-per-request pricing that eliminates idle costs, making Upstash potentially more economical for sporadic workloads and PlanetScale better for predictable database usage.
