Quart is a lightweight ASGI web application framework. It is a reimplementation of Flask using async/await. As with Flask Quart is designed to make getting started quick and easy, with the ability to scale up to complex applications. Quart is built on Werkzeug and uses Jinja for templating.

Quart offers suggestions, but doesn't enforce any dependencies or project layout. It is up to the developer to choose the tools and libraries they want to use. There are many extensions provided by the community that make adding new functionality easy.
