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
