DBWarden
The SQL-first database toolkit for SQLAlchemy.
DBWarden is a SQL-first migration system for SQLAlchemy that replaces Python-based migration workflows with explicit, reviewable SQL generated directly from your models. Unlike script-based migration tools, DBWarden does not introduce a migration runtime or require executing generated Python migration code. It produces plain SQL files that can be reviewed, versioned, and executed directly against any environment.
SQL-first
Migrations are plain SQL. No runtime required.
Rollback included
Every migration carries upgrade + rollback SQL.
Schema snapshots
Checksummed JSON after every migration for deterministic diffs.
Column-level diffing
Type, nullability, default, and comment changes.
Impact analysis
AST-based scan to detect breaking changes before deploy.
Offline mode
Export model state, generate migrations anywhere, no DB needed.
FastAPI integration
Startup validation, health checks, runtime lifecycle.
5 DB dialects
PostgreSQL, MySQL, MariaDB, SQLite, ClickHouse.
PyPI

with built-in TimestampMixin and SoftDeleteMixin. Eliminates repetitive schema boilerplate.
