## What it is
libSQL is an open source, open contribution fork of SQLite maintained by Turso, adding features like vector search, concurrent writes, async I/O, replication, and server access over the network. It ships as an embedded database engine with client SDKs for many languages and is fully backwards compatible with SQLite.

## Use cases
- embed a SQLite-compatible database in my app
- run vector similarity search for RAG without extensions
- sync a local database with a cloud replica
- replace SQLite with a drop-in fork that accepts contributions
- query a remote database over HTTP from TypeScript or Python
- run a database in the browser with WebAssembly
- store per-user or per-agent databases as files

## When to choose
- you need SQLite compatibility plus modern features like vector search, concurrent writes, or replication
- you want an embedded database that can also sync to or be accessed from the cloud
- you want to contribute improvements back to a SQLite fork under an MIT license

## When to avoid
- you need strict upstream SQLite with its conservative release process and wide third-party tooling guarantees
- you need a heavy multi-user client-server RDBMS like PostgreSQL with rich server-side features
- your stack depends on SQLite extensions or behaviors that libSQL may not track
