libSQL – SQLite-compatible database engine

libSQL is a fork of SQLite that extends the embedded relational database engine with additional functionality for distributed applications and remote database access.

Developed by Turso, libSQL retains compatibility with SQLite while introducing capabilities such as embedded replicas and a server component. Applications can continue using an embedded database model or connect to a remotely hosted database using libSQL interfaces.

The project retains SQLite’s familiar database format and much of its existing application programming interface. It also provides extensions to database functionality, including additional schema modification operations and facilities for custom database behaviour.

libSQL should be distinguished from the separate Turso database engine, which is a new implementation rather than a fork of SQLite.

This is free and open source software.

Key Features

  • SQLite-compatible relational database engine with additional database functionality.
  • Embedded operation allows applications to access databases without running a separate server process.
  • Embedded replicas provide locally accessible copies of remotely maintained databases.
  • libSQL server enables remote SQL database access over a network.
  • SQLite file format compatibility allows existing database files to be used with libSQL.
  • SQLite C API compatibility helps existing applications adopt the database engine.
  • Extended ALTER TABLE functionality supports additional column and constraint modifications.
  • Randomised ROWID support provides an alternative to conventional sequential row identifiers.
  • WebAssembly user-defined functions allow custom database operations.
  • Virtual write-ahead log interfaces provide additional control over database logging behaviour.
  • Client interfaces support integration with applications using Rust, JavaScript, Go and other languages.
