## What it is
aiohttp is an asynchronous HTTP client and server framework for Python built on asyncio. It supports client and server WebSockets out of the box and provides a web server with middleware, signals, and pluggable routing.

## Use cases
- make async http requests in python
- scrape many urls concurrently without blocking
- build an async rest api server in python
- serve websockets from a python backend
- replace requests with an async http client
- write middleware for request/response processing
- build a small web service without flask or django

## When to choose
- you need high-concurrency HTTP clients or servers in asyncio-based Python code
- you want WebSockets support on both client and server without extra dependencies
- you are building async APIs, crawlers, or microservices in Python

## When to avoid
- you want a simple synchronous HTTP client like requests
- you need a batteries-included web framework with ORM, auth, and admin like Django
- your codebase does not use asyncio

## Facets
- artifact type: library
- maturity: stable
- function: http-client, http-server, websocket, web-framework, routing, middleware
- domain: web-development, backend, apis, developer-tools
- platform: python, cross-platform
- tags: asyncio, async, http, websockets, client-server
