In their own words
SQLite
SQLite is a transactional SQL database engine that runs within an application, without a separate server process or configuration. Each complete database resides in a single disk file that works across platforms. Its SQL features include partial indexes, indexes on expressions, JSON, common table expressions, and window functions. Transactions are atomic, consistent, isolated, and durable, including after system crashes and power failures. A database file can have unlimited simultaneous readers, but only one writer at a time. The project recommends SQLite for device-local storage with low writer concurrency and less than a terabyte of content. SQLite is free for commercial or private use, with source code in the public domain. Downloads include source and precompiled binaries for Android, Linux, Mac OS X, and Windows, along with WebAssembly and JavaScript bundles for web applications. A free public forum is available, alongside paid private email and technical support options. The maker is based in Charlotte, North Carolina, and was founded in 2000.
