What is aiohttp used for?

aiohttp is used to build useful libraries built on top of it, and there’s a page dedicated to list them: Third-Party libraries. There are also projects that leverage the power of aiohttp to provide end-user tools, like command lines or software with full user interfaces.

What is aiohttp session?

HTTP sessions is an industry standard feature that allows Web servers to maintain user identity and to store user-specific data during multiple request/response interactions between a client application and a Web application.

Is FastAPI asynchronous?

FastAPI is a modern, fast (high-performance), a web framework for building APIs with Python. It is easy to learn, fast to code, and production-ready. The most exciting feature of FastAPI is that it supports asynchronous code out of the box using the async/await Python keywords.

Is aiohttp asgi?

This is a simple benchmark for python async frameworks. Almost all of the frameworks are ASGI-compatible (aiohttp and tornado are exceptions on the moment).
