Flask-Script

Flask-Script is a Python extension for Flask that provided support for writing external scripts, including running a development server, a customized Python shell, database setup scripts, and other command-line tasks. The project's last release was in September 2017 (version 2.0.6), and its maintainers are no longer actively developing new features, only merging pull requests. It has largely been superseded by Flask's built-in command-line interface (Flask CLI), which uses the Click library.
