An in-process SQL database, compatible with SQLite.

Turso Database is an in-process SQL database written in Rust, compatible with SQLite.

⚠️ Warning: This software is ALPHA, only use for development, testing, and experimentation. We are working to make it production ready, but do not use it for critical data right now.

• SQLite compatibility for SQL dialect, file formats, and the C API [see document for details]
• Change data capture (CDC) for real-time tracking of database changes.
• Language support for
  • Go
  • JavaScript
  • Java
  • Python
  • Rust
  • WebAssembly
• Asynchronous I/O support on Linux with io_uring
• Cross-platform support for Linux, macOS, Windows and browsers (through WebAssembly)
• Vector support support including exact search and vector manipulation
• Improved schema management including extended ALTER support and faster schema changes.

The database has the following experimental features:

• BEGIN CONCURRENT for improved write throughput using multi-version concurrency control (MVCC).
• Incremental computation using DBSP for incremental view mainatenance and query subscriptions.

The following features are on our current roadmap:

• Vector indexing for fast approximate vector search, similar to libSQL vector search.

Please see the Turso Database Manual for more information.

We'd love to have you contribute to Turso Database! Please check out the contribution guide to get started.

SQLite is loved because it is the most reliable database in the world. The next evolution of SQLite has to match or surpass this level of reliability. Turso is built with Deterministic Simulation Testing from the ground up, and is also tested by Antithesis.

Even during Alpha, if you find a bug that leads to a data corruption and demonstrate how our simulator failed to catch it, you can get up to $1,000.00. As the project matures we will increase the size of the prize, and the scope of the bugs.

More details here.

You can see an example of an awarded case on #2049.

Turso core staff are not eligible.

Turso Database is currently under heavy development and is not ready for production use.

Turso Database is a project to build the next evolution of SQLite in Rust, with a strong open contribution focus and features like native async support, vector search, and more. The libSQL project is also an attempt to evolve SQLite in a similar direction, but through a fork rather than a rewrite.

Rewriting SQLite in Rust started as an unassuming experiment, and due to its incredible success, replaces libSQL as our intended direction. At this point, libSQL is production ready, Turso Database is not - although it is evolving rapidly. More details here.
