Flask Backbone

[2023] Modern Flask Boilerplate with a well-organised structure.


Flask-Backbone is a Flask boilerplate that provides a predefined basic structure for building Flask applications. It is designed to be blueprint-first, allowing for a clean and steady structure. It offers database support via SQLAlchemy, although it is possible to use Flask-Backbone without a database. The boilerplate also includes features such as cache support, Flask-Debug, Sentry support, Jinja filters and custom variables, and interactive commands for creating blueprints. The installation process is straightforward, and the boilerplate is tested with Python 3.11.
