Uvicorn is an ASGI web server implementation for Python. Until recently Python has lacked a minimal low-level server/application interface for async frameworks. The ASGI specification fills this gap, and means we're now able to start building a common set of tooling usable across all async frameworks. Uvicorn currently supports HTTP/1.1 and WebSockets.

Features

  • The event loop uvloop will be installed and used if possible
  • The http protocol will be handled by httptools if possible
  • Most well established Python Web frameworks started out as WSGI-based frameworks
  • WSGI applications are a single, synchronous callable that takes a request and returns a response
  • A strength of the ASGI protocol is that it decouples the server implementation from the application framework
  • It is run widely in production, and supports HTTP/1.1, HTTP/2, and WebSockets
