Most tools add large frameworks and complex configuration. DBWarden focuses on a small CLI and readable SQL migrations.

Core ideas

• Auto detect SQLAlchemy models from a models directory • Generate raw SQL migration files from model changes • Keep migrations transparent and easy to review • Track migration history and database state • Minimal setup through a small warden.toml file

Typical workflow

1. Write SQLAlchemy models 2. Run dbwarden make-migrations "name" 3. Review the generated SQL 4. Run dbwarden migrate

Commands include

• init • make-migrations • migrate and rollback • history and status • diff between models and database

Supported databases

• PostgreSQL • SQLite • MySQL

Project status: experimental. I look for feedback from developers who work with SQLAlchemy migrations.
