SQLite

What is SQLite?

A C-language library that implements a small, fast, self-contained, high-reliability, full-featured SQL database engine. The most widely deployed database engine in the world, embedded in every mobile phone and most computers. Requires zero configuration, no server process, and stores the entire database in a single file. Used by applications like Firefox, Chrome, and Android. Known for its simplicity, reliability, and zero-maintenance design. Perfect for applications that need a database without the complexity of a database server.

When to use it

• Perfect for embedded databases, mobile applications, desktop applications, and small to medium web applications that don't require concurrent writes.
• Ideal when you need a zero-configuration database, want to avoid database server setup, or are building applications with simple data requirements.
• Excellent for development, testing, prototyping, and applications with low to medium traffic.
• Commonly used in mobile apps (iOS, Android), desktop applications, and small web applications.

When NOT to use it

• Applications requiring concurrent writes - SQLite locks the entire database
• High-traffic web applications - PostgreSQL or MySQL handle concurrency better
• When you need network access - SQLite is file-based only
• Large datasets that don't fit in memory - disk-based databases are better
