Turso vs Upstash

Turso takes SQLite and makes it work as a cloud database. Its design goal is many small databases rather than one big one: you can give every user, workspace or AI agent its own isolated database, and idle ones cost only storage. Embedded replication lets the same database run inside your app or on a user’s device, reading and writing locally and syncing with the cloud. Turso no longer offers edge replicas in multiple regions to new users.

The free tier gives you 5 GB of storage, 100 databases, 500 million row reads and 10 million row writes a month. Paid plans start with Developer at $4.99 a month billed yearly ($5.99 monthly) and Scaler at $24.92 billed yearly ($29 monthly). On 2 October 2026 Turso announced that it is being acquired by Supabase. It says the service keeps running as before and the open-source engine stays in active development; the announcement does not mention plan or price changes. If your app is read-heavy or naturally split per tenant, Turso is fast and cheap. If you need complex relational queries or heavy write throughput, Postgres on Neon or Supabase is a better foundation.

Upstash is Redis for the serverless world. Instead of paying $15-30/month for an always-on Redis instance, you pay per command, and when your app is idle, you pay nothing. This makes it perfect for caching, rate limiting, and session storage in serverless apps.

The free tier gives you 10,000 commands per day, which covers basic caching for most early-stage apps. The killer use case is pairing it with edge functions on Vercel or Cloudflare: Upstash has a global low-latency network designed for this. If you need full Redis compatibility or sub-millisecond latency, self-hosted Redis is still better. For everything else, Upstash saves you money and ops work.
