## What it is
Starlette is a lightweight, production-ready ASGI framework and toolkit for building async web services in Python. It provides HTTP and WebSocket support, routing, middleware, background tasks, and a test client with minimal dependencies.

## Use cases
- build an async web API in Python
- serve websockets in a lightweight app
- build a microservice with minimal dependencies
- create a base framework for other Python web tools
- add CORS, GZip, and static file serving to an ASGI app
- write async HTTP endpoints compatible with asyncio and trio

## When to choose
- you want a lightweight async Python web framework with few dependencies
- you need WebSocket support alongside HTTP
- you are building FastAPI-like frameworks or want fine-grained control
- performance against benchmarks matters

## When to avoid
- you want batteries-included features like ORM, auth, and admin out of the box
- you prefer a synchronous WSGI stack
- you need a full-stack framework with built-in templating-heavy workflows

## Facets
- artifact type: framework
- maturity: stable
- function: web-framework, http-server, websocket, routing, middleware, templating, testing
- domain: web-development, backend, apis, developer-tools
- platform: python, cross-platform
- tags: asgi, asyncio, trio, http, websockets, lightweight, uvicorn, web-server
