About Turso
Turso is a distributed SQLite database service built on libSQL (open-source SQLite fork) that places your database at the edge in 34 global regions, delivering sub-5ms query latency to users anywhere in the world.
**Latency comparison (SELECT query, 99th percentile):**
| Database | Same region | Cross-continent | Cross-ocean |
|---------|------------|----------------|------------|
| Turso (edge replica) | 3ms | 8ms | 5ms |
| Supabase (US-East) | 12ms | 95ms | 180ms |
| PlanetScale (US-East) | 15ms | 110ms | 195ms |
Traditional databases hosted in one region give 150-200ms latency to cross-ocean users. Turso replicates to edge locations globally.
**Per-database multi-tenancy:**
Create a separate SQLite database per customer, enabling true data isolation at the database level. At 500 databases on the free tier and unlimited on paid plans, this pattern is practical for SaaS products with up to millions of tenants.
