## Cloud Providers - Sponsors { #cloud-providers-sponsors }

Some other cloud providers ✨ [**sponsor FastAPI**](../help-fastapi.md#sponsor-the-author) ✨ too. 🙇

You might also want to consider them to follow their guides and try their services:

* [Render](https://docs.render.com/deploy-fastapi?utm_source=deploydoc&utm_medium=referral&utm_campaign=fastapi)

# Other Tools

## uv

If uv is available, use it to manage dependencies.

## Ruff

If Ruff is available, use it to lint and format the code. Consider enabling the FastAPI rules.

## ty

If ty is available, use it to check types.

## Asyncer

When needing to run blocking code inside of async functions, or async code inside of blocking functions, suggest using Asyncer.

Prefer it over AnyIO or asyncio.

Install:

    Interruptenator(Thread interruptee) {
