I totally agree on SQLAlchemy. It’s very good. As is Alembic. I feel like most using Flask would consider “Flask components” to be equivalent to Flask extensions—e.g., Flask-SQLAlchemy vs SQLAlchemy proper. Maybe it’s a pedantic nitpick, but I’ve never heard anyone refer to SQLAlchemy as a Flask component in 5+ years, hence my comment about the distinction. But yes, many of the Flask-compatible Python packages you mentioned are quite a joy to use.
