Uvicorn vs CometD: 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.; CometD: WebSocket & HTTP, highly scalable and clustered web messaging framework. It is a web server to push data to a browser, without the browser explicitly requesting it. It is an umbrella term, encompassing multiple techniques for achieving this interaction.

Uvicorn and CometD can be primarily classified as "Web Servers" tools.

Some of the features offered by Uvicorn are:

• ASGI server implementation

• Javascript Client
• Publish/Subscribe Messaging
