Object-Relational Mapping tools for database interactions in Python.
Python ORMs let you interact with relational databases using Python objects instead of raw SQL, making database code more readable and maintainable. The most established option is SQLAlchemy, which offers both a high-level ORM layer and a lower-level SQL expression API — giving you full control when you need it. Django ORM is tightly integrated into the Django framework and is the natural choice for Django web applications. Peewee offers a lightweight alternative for smaller projects and microservices. For async workloads such as FastAPI backends and asyncio-based data pipelines, Tortoise ORM and Gino provide async-native interfaces. Pony ORM takes a different approach, letting you write queries as Python generator expressions that are automatically translated to SQL.

Choose SQLAlchemy for complex, production-grade applications — it handles any database backend and supports both a full ORM and raw SQL expressions, making it the most versatile choice for data engineering pipelines. Use Django ORM inside Django projects; it integrates seamlessly with migrations, admin, and Django's authentication system. Peewee is ideal for lightweight services where you want a simpler, less verbose ORM with minimal setup. For async applications using FastAPI or asyncio, Tortoise ORM offers a Django-like API built natively for async workflows. Pony ORM is a good fit if you prefer writing queries as Python generator expressions. For most new projects, SQLAlchemy or Tortoise ORM covers the majority of use cases.
