Quart is a Python ASGI web microframework. It is intended to provide the easiest way to use asyncio functionality in a web context, especially with existing Flask apps. This is possible as the Quart API is a superset of the Flask API.

Quart aims to be a complete web microframework, as it supports HTTP/1.1, HTTP/2 and websockets. Quart is very extendable and has a number of known extensions and works with many of the Flask extensions.

Quart supports the full ASGI 3.0 specification as well as the websocket response and HTTP/2 server push extensions. For those of you familiar with Flask, Quart extends the Flask API by adding support for:

* HTTP/1.1 request streaming * Websockets * HTTP/2 server push
