About Turso
Turso is an edge-native SQLite database platform founded in 2022 by Glauber Costa and Jorge Pedreira, built on libSQL — an open-source fork of SQLite with replication and network access. Turso's core thesis is that SQLite's simplicity, speed, and embedded nature should be available as a distributed cloud database — one database per tenant, not one shared database for all tenants. Turso's multi-tenancy model enables creating hundreds or thousands of individual SQLite databases per account, making it the ideal choice for multi-tenant SaaS applications where each customer gets an isolated database (vs fighting connection limits and query isolation in shared Postgres). Turso's edge replication places database replicas close to users across 35+ PoPs (points of presence) globally — reads return in single-digit milliseconds from edge locations, making Turso one of the fastest databases for globally distributed applications. Turso's free tier is among the most generous: 500 databases, 9GB total storage, 1 billion row reads/month — enabling multi-tenant apps with hundreds of users at zero cost. Turso integrates natively with Cloudflare Workers, Vercel Edge Functions, Remix, SvelteKit, Astro, and Next.js edge runtime via the @libsql/client JavaScript SDK. Turso supports SQLite's embedded replica mode — run a local SQLite replica with sync, enabling offline-capable applications that sync to Turso when online. Turso raised $32M in 2024 and positions itself as the database for multi-tenant SaaS, edge-first applications, and the millions of SQLite-native mobile/desktop apps that need cloud sync.
Frequently Asked Questions
Why use one database per tenant (Turso's model) vs one shared database?
Per-tenant database isolation (Turso's approach) provides complete data isolation (no accidental cross-tenant queries), simpler compliance (GDPR delete is just deleting the database), per-tenant backup and migration, and natural sharding. The tradeoff is managing many databases vs one. Turso's API makes creating/deleting databases programmatic. Shared database multi-tenancy (Supabase, Neon, Postgres with RLS) is simpler for small user counts but gets complex at enterprise scale.
How fast is Turso compared to other databases?
Turso's edge replicas deliver reads in 1-5ms from nearby PoPs vs 20-100ms+ for centralized databases in the wrong region. SQLite's embedded nature (no client-server protocol overhead) makes individual queries faster than Postgres/MySQL for simple reads. For write-heavy workloads, reads go to the edge replica while writes route to the primary, adding ~50-100ms of write latency. Turso is the fastest option for globally distributed read-heavy applications.
Is Turso production-ready?
Yes — Turso is production-ready for edge-native and multi-tenant applications. Companies use Turso in production for SaaS applications with per-customer database isolation. Turso's managed service includes automated backups, point-in-time recovery, and 99.9% SLA. For mission-critical applications requiring PostgreSQL's full feature set (complex joins, advanced types, mature ecosystem), Neon or Supabase are more appropriate.
