Hypercorn

Hypercorn is an ASGI (Asynchronous Server Gateway Interface) web server designed for running Python web applications, particularly those built with async frameworks like FastAPI, Starlette, or Quart. It supports HTTP/1, HTTP/2, and WebSocket protocols, offering high performance and scalability for modern asynchronous Python web development. It is often used as a production server for deploying ASGI-based applications.

Also known as: Hypercorn ASGI, Hypercorn server, Hypercorn web server, ASGI Hypercorn, Hypercorn HTTP server

Why learn Hypercorn?

Developers should use Hypercorn when deploying ASGI-compatible applications that require asynchronous handling, such as real-time APIs, WebSocket services, or high-concurrency web apps. It is ideal for production environments due to its support for HTTP/2, which improves performance with features like multiplexing, and its compatibility with async frameworks like FastAPI, making it a robust choice for modern Python web stacks.
