Turso
Rust rewrite of SQLite plus a cloud service, giving every user, agent, and tenant its own database that runs offline, in the browser, or on device.
About
Turso builds an embedded database engine described as a Rust based rewrite of SQLite designed for distributed architectures, an engine that goes anywhere: offline, in the browser, or on device. Features include native vector search, an async design using Linux io_uring, concurrent writes without locking, and browser support through WebAssembly and OPFS.
Turso Cloud is the hosted service, offering unlimited SQLite databases that never sleep, accessible over the network or synced to a user's own devices. The company's framing is to spin a database for every user, agent, and tenant, noting that databases are files rather than processes, so there are no cold starts, no scale to zero, and no wake up penalty.
It is positioned as fully backwards compatible SQLite built for the next generation of agents, targeting AI agents, mobile and IoT applications, and multi tenant systems that need data isolation and vector search for retrieval augmented generation.
