Questions tagged [quart]

Quart is a microframework for developing web applications using Python's asyncio library.

Quart is an evolution of the Flask API to work with Asyncio and to provide a number of features not present or possible in Flask.

Compatibility with the Flask API is, however, the main aim, which means that the Flask documentation is an additional useful source of help.

The latest documentation for Quart can be found here

Quart is developed on GitLab. You are very welcome to open issues or propose merge requests.
