Turso

Distributed SQLite database built for edge deployments and low-latency global apps.

Overview

Turso is a modern database built on SQLite, designed for the era of AI agents and distributed applications. It provides both a cloud service (Turso Cloud) and an embedded engine that can run anywhere—on servers, in browsers, on devices, or offline. Unlike traditional databases built around a single shared instance, Turso is architected for a many-database model where each agent, user, or tenant gets their own lightweight database.

The platform combines SQLite's simplicity and compatibility with cloud-native features including concurrent writes, vector search for AI/RAG workflows, replication and sync capabilities, and branching for isolated testing. Turso databases are files rather than processes, eliminating cold starts and enabling instant availability. It's available as both a managed cloud service and as open-source SDKs for embedding directly in applications.

Use this if

You need a scalable database for AI agents, want to deploy databases per user/tenant, require vector search capabilities, or are building offline-first mobile applications.

Skip this if

You need traditional relational database features like complex joins across many tables, require full ACID transactions with multiple writers on a single database, or prefer managed services without open-source components.
