Versioned schema migrations for SQLAlchemy projects. It can autogenerate a migration by diffing your models against the database, which you then review and commit.

Reach for it when:
- Evolving a Postgres or MySQL schema in a Python project

Worth knowing: Autogenerate misses some changes, such as renames — always read the generated migration.
