SQLite is currently found in more applications than we can count, including several high-profile projects.
The code for SQLite is in the public domain and is thus free for use for any purpose, commercial or private. SQLite is a in-process library that implements a self-contained, serverless, zero-configuration, transactional SQL database engine.
