Cada programa de servidor ASGI alternativo teria um comando semelhante, você pode ler mais na documentação respectiva.

/// warning | Aviso

Uvicorn e outros servidores suportam a opção `--reload` que é útil durante o desenvolvimento.

A opção `--reload` consome muito mais recursos, é mais instável, etc.

Ela ajuda muito durante o **desenvolvimento**, mas você **não deve** usá-la em **produção**.
