Hypercorn is an ASGI web server based on the sans-io hyper, h11, h2, and wsproto libraries and inspired by Gunicorn. Hypercorn supports HTTP/1, HTTP/2, and websockets and the ASGI 2 specification. Hypercorn can utilise asyncio, uvloop, or trio worker types.

Hypercorn was initially part of Quart before being separated out into a standalone ASGI server. Hypercorn forked from version 0.5.0 of Quart.

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