Saffier is an asynchronous Python object-relational mapper built directly on SQLAlchemy 2.x Async. It provides a Python-native model layer with a familiar, Django-inspired interface for defining models and working with relational databases.
The ORM is framework-agnostic and can be integrated with ASGI frameworks including FastAPI, Starlette, Sanic, Quart and Lilya. It supports PostgreSQL, MySQL, MariaDB and SQLite through optional asynchronous database drivers.
This is free and open source software.
