zombiezen/go-sqlite is a Go library providing low-level bindings to SQLite 3 using the CGo-free modernc.org/sqlite implementation. It offers direct access to SQLite features including connection management, statement execution, blob I/O streaming, online backup API, user-defined functions (scalar and aggregate), session API for changesets, virtual table support, and schema migration tools. The architecture follows a modular design with core sqlite package for basic operations, sqlitex for extended utilities (connection pooling, execution helpers), sqlitefile for blob-backed buffers, and sqlitemigration for schema migrations. The library is safe for concurrent use through connection pooling and proper error handling, with comprehensive test coverage demonstrating its reliability.
