    !!! tip
        By adding the `standard`, Uvicorn will install and use some recommended extra dependencies.

        That including `uvloop`, the high-performance drop-in replacement for `asyncio`, that provides the big concurrency performance boost.

        When you install FastAPI with something like `pip install fastapi` you already get `uvicorn[standard]` as well.

=== "Hypercorn"

Néanmoins, Uvicorn n'est actuellement compatible qu'avec asyncio, et il utilise normalement <a href="https://github.

Mais si vous souhaitez utiliser directement **Trio**, vous pouvez utiliser **Hypercorn** car il le prend en charge. ✨
