FastAPI Cloud, best practices by default

We're hard at work making sure FastAPI Cloud has the best practices (sensible defaults) in place, by default, so you don't have to worry about it and can focus on building amazing apps with FastAPI. 🚀

We are reinforcing security, scalability, reliability... We want you to have the best developer experience, in a Python-native way, as soon as we invite you to join FastAPI Cloud. 😎

FastAPI CLI with entrypoints

Now FastAPI CLI supports the "entrypoint" syntax to define the app you want to run:

# Entrypoint syntax
fastapi run -e some.importable_module:app_name

# Paths are still supported too
fastapi run some/importable_module.py

Go and upgrade your FastAPI version:

# Upgrade with uv
uv add --upgarde "fastapi[standard]"

# Or manually with pip
pip install --upgrade "fastapi-cli"
