dbconform is a Python library that repairs database schema drift by comparing live databases against SQLAlchemy or SQLModel models, without requiring migration history. It offers a programmatic, in-process approach to schema conformance with safe defaults and support for complex operations like NOT NULL backfills and SQLite table rebuilds, filling a clear gap left by Alembic and other tools.

Target audience: backend devs, data engineers, devops
