FastAPI is a modern, fast (high-performance), web framework for building APIs with Python based on standard Python type hints.

The key features are:

* **Fast**: Very high performance, on par with **NodeJS** and **Go** (thanks to Starlette and Pydantic). [One of the fastest Python frameworks available](#performance).
* **Fast to code**: Increase the speed to develop features by about 200% to 300%. *

    // Seems important on Windows
    "ALLUSERSPROFILE",
    "PUBLIC",
    "windir",

    // Used by performance test to recognize TeamCity buildId
    "BUILD_ID",
    // Used by some tests to be ignored in specific build

    "JPROFILER_HOME",

    // Used by mirror init script, see RepoScriptBlockUtil

    return delegateCollection().isPartialView();

/// 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[standard]"` you already get `uvicorn[standard]` as well.

E esse é o mesmo nível de performance que você tem com o **FastAPI**.
