## What it is
Piccolo is a fast, user-friendly ORM and query builder for Python with first-class asyncio support. It includes batteries like migrations, a User model, authentication, and integrates with ASGI frameworks such as FastAPI and Starlette.

## Use cases
- query a postgres database with async python
- orm for fastapi app
- build a web app with sqlite and asyncio
- manage database migrations in python
- type-annotated query builder for python
- add user authentication to a python backend
- scaffold an asgi web app with an orm

## When to choose
- you need async or sync database access in Python with Postgres or SQLite
- you want a modern, fully type-annotated ORM with tab completion
- you're building an ASGI web app (FastAPI, Starlette, Litestar, etc.) and want an integrated ORM with migrations and auth

## When to avoid
- you need databases other than Postgres, SQLite, or CockroachDB
- your team is heavily invested in Django ORM or SQLAlchemy ecosystems
- you need a synchronous-only, minimal ORM without extra batteries

## Facets
- artifact type: library
- maturity: active
- function: orm, database, auth, middleware
- domain: databases, web-development, backend, developer-tools
- platform: python, cross-platform
- tags: asyncio, query-builder, postgresql, sqlite, asgi, fastapi, migrations, type-annotated
