SQLite
SQLite is an open-source, embedded, relational database management system, designed circa 2000. It is a database, with zero configuration, no requirements of a server or installation. Despite its simplicity, it is laden with popular features of database management systems.
About SQLite
SQLite is a C-language library implementing a self-contained, serverless SQL database engine. It is embedded directly into applications rather than run as a separate server process, and is used across mobile phones, computers, and many other applications. The source code is in the public domain and free to use for any purpose.
The engine is designed to be small, fast, and reliable, supporting standard SQL syntax along with date and time functions, aggregate functions, window functions, math functions, and JSON functions. It provides a C/C++ interface with a documented API, as well as a TCL interface.
It is suited for developers who need an embedded database engine within an application rather than a standalone client-server database system. The latest release at the time of the page was version 3.53.4, dated 2026-07-24.
