Django projects often call for a robust, powerful setup to ensure a smooth development and deployment process. Cookiecutter Django is a popular framework that aims to offer Django users a comprehensive, out-of-the-box setup, including configurations for databases, templates, and much more. Cookiecutter Django exclusively supports PostgreSQL, reflecting its intention for production-level applications where PostgreSQL's advanced features can be a real asset. However, there might be scenarios where a developer wants to use SQLite instead, perhaps for small-scale applications, quick prototypes, or simply due to personal preference or familiarity with SQLite.
