SQLModel
SQLModel is a Python library that sits on top of SQLAlchemy and Pydantic to define relational models with a single typed model layer.
Where it fits
It is a practical middle ground for projects that want the convenience of shared model definitions across validation and persistence without dropping down immediately into lower-level SQLAlchemy patterns.
Repeated project patterns
- Status Alganize uses SQLModel in a standard FastAPI CRUD stack.
- MaRESS uses SQLModel in a more research-heavy backend that also touches spatial and extraction workflows.
- Study Duel uses SQLModel alongside realtime game logic and conventional relational data.
Trade-offs
- It is productive for many application backends, but advanced SQLAlchemy features can still surface underneath.
- Migration discipline through Alembic remains necessary.
