Database migration tool for SQLAlchemy. Manages schema versioning via migration scripts. Current version: 1.18.4 (Mar 2026). Tightly coupled to SQLAlchemy — version mismatch causes silent failures. SQLAlchemy 1.3 dropped in Alembic 1.15. Python 3.8 dropped in Alembic 1.15. The #1 footgun: autogenerate generates empty migrations when target_metadata is not correctly set in env.py.
