Features

  • WSGI support for Django, Flask, Pyramid, and any WSGI framework
  • ASGI support for FastAPI, Starlette, Quart
  • HTTP/2 support (beta) with multiplexed streams
  • Dirty Arbiters (beta) for heavy workloads (ML models, long-running tasks)
  • uWSGI binary protocol for nginx integration
  • Multiple worker types: sync, gthread, gevent, eventlet, asgi
