Uvicorn vs Gunicorn: What are the differences?

Uvicorn: The lightning-fast ASGI server. It is a lightning-fast ASGI server, built on uvloop and httptools Until recently Python has lacked a minimal low-level server/application interface for asyncio frameworks. The ASGI specification fills this gap, and means we're now able to start building a common set of tooling usable across all asyncio frameworks.; Gunicorn: A Python WSGI HTTP Server for UNIX. Gunicorn is a pre-fork worker model ported from Ruby's Unicorn project. The Gunicorn server is broadly compatible with various web frameworks, simply implemented, light on server resources, and fairly speedy.

Uvicorn and Gunicorn belong to "Web Servers" category of the tech stack.
