Flask-Migrate is a Flask extension that wraps Alembic to handle SQLAlchemy database migrations. It exposes migration operations as command-line arguments under the `flask db` command.

Use cases

• manage sqlalchemy schema migrations in a flask app
• create and apply database migrations with flask db commands
• version control database schema changes for a flask project
• sync database schema across environments using alembic
• upgrade an existing flask database schema after model changes

When to choose

• you have a Flask application using Flask-SQLAlchemy or SQLAlchemy and need schema migrations
• you want Alembic migrations integrated with Flask's CLI
• you need reproducible database upgrades across development and production

When to avoid

• your project does not use Flask or SQLAlchemy
• you need migrations for non-SQL databases
• you use a different web framework with its own migration tooling
