About Turso
Turso is a ground-up rewrite of SQLite that adds modern, cloud-native features like concurrent writes, native vector search, and asynchronous replication. It's designed to run anywhere—in the cloud, on-device, or in the browser with WebAssembly. The Turso Cloud platform provides unlimited, always-on SQLite databases that can be accessed via a network API or synced directly to devices for local-first applications. Key features include copy-on-write branching for isolated development, performance analytics, and built-in support for AI/RAG workflows. Turso is ideal for building multi-tenant SaaS, scalable AI agents, and offline-capable mobile and IoT applications.
Core Database Engine Features
Sqlite Compatible
Fully backwards compatible with the SQLite ecosystem.
Concurrent Writes
Supports multiple writers without conflicts or locking.
Vector Search
Native similarity search for AI apps and RAG workflows, no extensions required.
Async Design
Built with modern async primitives like Linux io_uring for responsive applications.
Wasm Support
Runs in the browser with WebAssembly & the Origin Private File System (OPFS).
Turso Cloud Platform
Unlimited Databases
Create a database for every user, tenant, or agent. Idle databases only incur storage costs.
Always On
Databases are files, not processes, resulting in no cold starts or wake-up penalties.
Replication & Sync
Keep on-device or edge databases in sync with the cloud platform.
Branching
Instantly create isolated copy-on-write branches of your database.
Analytics
Monitor performance and usage across all your databases.
Primary Use Cases
Ai Agents
Scale to millions of agents with unlimited databases and built-in vector search for LLMs.
Mobile & Iot
Build local-first, on-device apps that can write offline and sync later.
Multi-Tenancy
Achieve data isolation and massive scalability with a database-per-tenant architecture.
