Hypercorn is an ASGI <https://github.com/django/asgiref/blob/main/specs/asgi.rst> and WSGI web server based on the sans-io hyper, h11 <https://github.com/python-hyper/h11>, h2 <https://github.com/python-hyper/hyper-h2>, and wsproto <https://github.com/python-hyper/wsproto> libraries and inspired by Gunicorn. Hypercorn supports HTTP/1, HTTP/2, WebSockets (over HTTP/1 and HTTP/2), ASGI, and WSGI specifications. Hypercorn can utilise asyncio, uvloop, or trio worker types.

Hypercorn can optionally serve the current draft of the HTTP/3 specification using the aioquic <https://github.com/aiortc/aioquic/>_ library. To enable this install the h3 optional extra, pip install hypercorn[h3] and then choose a quic binding e.g. hypercorn --quic-bind localhost:4433 ....

Hypercorn was initially part of Quart <https://github.com/pgjones/quart>_ before being separated out into a standalone server. Hypercorn forked from version 0.5.0 of Quart.

Quickstart

Hypercorn can be installed via pip <https://docs.python.org/3/installing/index.html>_,

.. code-block:: console

$ pip install hypercorn

and requires Python 3.8 or higher.

With hypercorn installed ASGI frameworks (or apps) can be served via Hypercorn via the command line,

.. code-block:: console

$ hypercorn module:app

Alternatively Hypercorn can be used programatically,

.. code-block:: python

import asyncio
from hypercorn.config import Config
from hypercorn.asyncio import serve

from module import app

asyncio.run(serve(app, Config()))

learn more (including a Trio example of the above) in the API usage <https://hypercorn.readthedocs.io/en/latest/how_to_guides/api_usage.html>_ docs.
