Uvicorn ASGI Server

Overview

Uvicorn is a lightning-fast ASGI server implementation for Python. Built on top of uvloop and httptools, it provides a minimal, high-performance interface for running asynchronous web frameworks such as FastAPI, Starlette, and other ASGI-compatible applications. Uvicorn supports HTTP/1.1, HTTP/2 (via the [standard] extras), WebSockets, and lifespan protocol events out of the box.

Key characteristics:

• High-throughput async I/O powered by uvloop (when installed)
• First-class support for FastAPI and Starlette applications
• Built-in hot reload for development workflows
• Multiprocess worker mode for production deployments
• SSL/TLS termination support
• WebSocket and HTTP/2 protocol support
• ASGI lifespan event handling for startup/shutdown logic
