## What it is
Peewee is a small, expressive Python ORM with a flexible query builder that supports SQLite, MySQL/MariaDB, and PostgreSQL, plus asyncio backends. It is a single dependency-free module in production use since 2010, with schema migrations and framework integrations for Flask, FastAPI, and Pydantic.

## Use cases
- define database models and query tables in python
- use an orm with sqlite in a small python app
- add postgresql or mysql persistence to a flask or fastapi app
- run async database queries with asyncio
- generate and run schema migrations for a python project
- write raw sql with a lightweight query builder
- avoid heavy orms like sqlalchemy for simple projects

## When to choose
- you want a lightweight, easy-to-learn ORM with no required dependencies
- your app uses SQLite, MySQL/MariaDB, or PostgreSQL in Python
- you need asyncio database access built on standard async drivers
- you want expressive query building while retaining full SQL power

## When to avoid
- you need a multi-database ORM with advanced features like SQLAlchemy's ecosystem
- you require an async-first ORM with deep async ecosystem integration
- you need databases beyond the DB-API 2.0 drivers Peewee supports

## Facets
