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%. * * **Fewer bugs**: Reduce about 40% of human (developer) induced errors. * * **Intuitive**: Great editor support. <abbr title="also known as auto-complete, autocompletion, IntelliSense">Completion</abbr> everywhere. Less time debugging. * **Easy**: Designed to be easy to use and learn. Less time reading docs. * **Short**: Minimize code duplication. Multiple features from each parameter declaration. Fewer bugs. * **Robust**: Get production-ready code. With automatic interactive documentation. * **Standards-based**: Based on (and fully compatible with) the open standards for APIs: <a href="https://github.com/OAI/OpenAPI-Specification" class="external-link" target="_blank">OpenAPI</a> (previously known as Swagger) and <a href="https://json-schema.org/" class="external-link" target="_blank">JSON Schema</a>. <small>* estimation based on tests on an internal development team, building production applications.</small> ## Sponsors <!-- sponsors --> <a href="https://blockbee.io?ref=fastapi" target="_blank" title="BlockBee Cryptocurrency Payment Gateway"><img src="https://fastapi.tiangolo.com/img/sponsors/blockbee.png"></a> <a href="https://github.com/scalar/scalar/?utm_source=fastapi&utm_medium=website&utm_campaign=main-badge" target="_blank" title="Scalar: Beautiful Open-Source API References from Swagger/OpenAPI files"><img src="https://fastapi.tiangolo.com/img/sponsors/scalar.svg"></a> <a href="https://www.propelauth.com/?utm_source=fastapi&utm_campaign=1223&utm_medium=mainbadge" target="_blank" title="Auth, user management and more for your B2B product"><img src="https://fastapi.tiangolo.com/img/sponsors/propelauth.png"></a> <a href="https://zuplo.link/fastapi-gh" target="_blank" title="Zuplo: Deploy, Secure, Document, and Monetize your FastAPI"><img src="https://fastapi.tiangolo.com/img/sponsors/zuplo.png"></a> <a href="https://liblab.com?utm_source=fastapi" target="_blank" title="liblab - Generate SDKs from FastAPI"><img src="https://fastapi.tiangolo.com/img/sponsors/liblab.png"></a> <a href="https://docs.render.com/deploy-fastapi?utm_source=deploydoc&utm_medium=referral&utm_campaign=fastapi" target="_blank" title="Deploy & scale any full-stack web app on Render.

INFO: Application startup complete. ``` </div> <details markdown="1"> <summary>About the command <code>fastapi dev main.py</code>...</summary> The command `fastapi dev` reads your `main.py` file, detects the **FastAPI** app in it, and starts a server using <a href="https://www.uvicorn.org" class="external-link" target="_blank">Uvicorn</a>. By default, `fastapi dev` will start with auto-reload enabled for local development. You can read more about it in the <a href="https://fastapi.tiangolo.com/fastapi-cli/" target="_blank">FastAPI CLI docs</a>. </details> ### Check it Open your browser at <a href="http://127.0.0.1:8000/items/5?q=somequery" class="external-link" target="_blank">http://127.0.0.1:8000/items/5?q=somequery</a>. You will see the JSON response as: ```JSON {"item_id": 5, "q": "somequery"} ``` You already created an API that: * Receives HTTP requests in the _paths_ `/` and `/items/{item_id}`. * Both _paths_ take `GET` <em>operations</em> (also known as HTTP _methods_). * The _path_ `/items/{item_id}` has a _path parameter_ `item_id` that should be an `int`. * The _path_ `/items/{item_id}` has an optional `str` _query parameter_ `q`. ### Interactive API docs Now go to <a href="http://127.0.0.1:8000/docs" class="external-link" target="_blank">http://127.0.0.1:8000/docs</a>. You will see the automatic interactive API documentation (provided by <a href="https://github.com/swagger-api/swagger-ui" class="external-link" target="_blank">Swagger UI</a>):  ### Alternative API docs And now, go to <a href="http://127.0.0.1:8000/redoc" class="external-link" target="_blank">http://127.0.0.1:8000/redoc</a>. You will see the alternative automatic documentation (provided by <a href="https://github.com/Rebilly/ReDoc" class="external-link" target="_blank">ReDoc</a>):  ## Example upgrade Now modify the file `main.py` to receive a body from a `PUT` request. Declare the body using standard Python types, thanks to Pydantic. ```Python hl_lines="4 9-12 25-27" from typing import Union from fastapi import FastAPI from pydantic import BaseModel app = FastAPI() class Item(BaseModel): name: str price: float is_offer: Union[bool, None] = None @app.get("/") def read_root(): return {"Hello": "World"} @app.get("/items/{item_id}") def read_item(item_id: int, q: Union[str, None] = None): return {"item_id": item_id, "q": q} @app.put("/items/{item_id}") def update_item(item_id: int, item: Item): return {"item_name": item.name, "item_id": item_id} ``` The `fastapi dev` server should reload automatically. ### Interactive API docs upgrade Now go to <a href="http://127.0.0.1:8000/docs" class="external-link" target="_blank">http://127.0.0.1:8000/docs</a>. * The interactive API documentation will be automatically updated, including the new body:  * Click on the button "Try it out", it allows you to fill the parameters and directly interact with the API:  * Then click on the "Execute" button, the user interface will communicate with your API, send the parameters, get the results and show them on the screen:  ### Alternative API docs upgrade And now, go to <a href="http://127.0.0.1:8000/redoc" class="external-link" target="_blank">http://127.0.0.1:8000/redoc</a>. * The alternative documentation will also reflect the new query parameter and body:  ### Recap In summary, you declare **once** the types of parameters, body, etc. as function parameters. You do that with standard modern Python types. You don't have to learn a new syntax, the methods or classes of a specific library, etc. Just standard **Python**. For example, for an `int`: ```Python item_id: int ``` or for a more complex `Item` model: ```Python item: Item ``` ...and with that single declaration you get: * Editor support, including: * Completion. * Type checks. * Validation of data: * Automatic and clear errors when the data is invalid. * Validation even for deeply nested JSON objects. * <abbr title="also known as: serialization, parsing, marshalling">Conversion</abbr> of input data: coming from the network to Python data and types. Reading from: * JSON. * Path parameters. * Query parameters. * Cookies. * Headers. * Forms. * Files. * <abbr title="also known as: serialization, parsing, marshalling">Conversion</abbr> of output data: converting from Python data and types to network data (as JSON): * Convert Python types (`str`, `int`, `float`, `bool`, `list`, etc). * `datetime` objects. * `UUID` objects. * Database models. * ...and many more. * Automatic interactive API documentation, including 2 alternative user interfaces: * Swagger UI. * ReDoc. --- Coming back to the previous code example, **FastAPI** will: * Validate that there is an `item_id` in the path for `GET` and `PUT` requests. * Validate that the `item_id` is of type `int` for `GET` and `PUT` requests. * If it is not, the client will see a useful, clear error. * Check if there is an optional query parameter named `q` (as in `http://127.0.0.1:8000/items/foo?q=somequery`) for `GET` requests. * As the `q` parameter is declared with `= None`, it is optional. * Without the `None` it would be required (as is the body in the case with `PUT`). * For `PUT` requests to `/items/{item_id}`, read the body as JSON: * Check that it has a required attribute `name` that should be a `str`. * Check that it has a required attribute `price` that has to be a `float`. * Check that it has an optional attribute `is_offer`, that should be a `bool`, if present. * All this would also work for deeply nested JSON objects. * Convert from and to JSON automatically. * Document everything with OpenAPI, that can be used by: * Interactive documentation systems. * Automatic client code generation systems, for many languages. * Provide 2 interactive documentation web interfaces directly. --- We just scratched the surface, but you already get the idea of how it all works. Try changing the line with: ```Python return {"item_name": item.name, "item_id": item_id} ``` ...from: ```Python ... "item_name": item.name ... ``` ...to: ```Python ... "item_price": item.price ... ``` ...and see how your editor will auto-complete the attributes and know their types:  For a more complete example including more features, see the <a href="https://fastapi.tiangolo.com/tutorial/">Tutorial - User Guide</a>. **Spoiler alert**: the tutorial - user guide includes: * Declaration of **parameters** from other different places as: **headers**, **cookies**, **form fields** and **files**. * How to set **validation constraints** as `maximum_length` or `regex`. * A very powerful and easy to use **<abbr title="also known as components, resources, providers, services, injectables">Dependency Injection</abbr>** system. * Security and authentication, including support for **OAuth2** with **JWT tokens** and **HTTP Basic** auth. * More advanced (but equally easy) techniques for declaring **deeply nested JSON models** (thanks to Pydantic). * **GraphQL** integration with <a href="https://strawberry.rocks" class="external-link" target="_blank">Strawberry</a> and other libraries. * Many extra features (thanks to Starlette) as: * **WebSockets** * extremely easy tests based on HTTPX and `pytest` * **CORS** * **Cookie Sessions** * ...and more. ## Performance Independent TechEmpower benchmarks show **FastAPI** applications running under Uvicorn as <a href="https://www.techempower.com/benchmarks/#section=test&runid=7464e520-0dc2-473d-bd34-dbdfd7e85911&hw=ph&test=query&l=zijzen-7" class="external-link" target="_blank">one of the fastest Python frameworks available</a>, only below Starlette and Uvicorn themselves (used internally by FastAPI). (*) To understand more about it, see the section <a href="https://fastapi.tiangolo.com/benchmarks/" class="internal-link" target="_blank">Benchmarks</a>. ## Dependencies FastAPI depends on Pydantic and Starlette. ### `standard` Dependencies When you install FastAPI with `pip install "fastapi[standard]"` it comes with the `standard` group of optional dependencies: Used by Pydantic: * <a href="https://github.com/JoshData/python-email-validator" target="_blank"><code>email-validator</code></a> - for email validation. Used by Starlette: * <a href="https://www.python-httpx.org" target="_blank"><code>httpx</code></a> - Required if you want to use the `TestClient`. * <a href="https://jinja.palletsprojects.com" target="_blank"><code>jinja2</code></a> - Required if you want to use the default template configuration. * <a href="https://github.com/Kludex/python-multipart" target="_blank"><code>python-multipart</code></a> - Required if you want to support form <abbr title="converting the string that comes from an HTTP request into Python data">"parsing"</abbr>, with `request.form()`. Used by FastAPI: * <a href="https://www.uvicorn.org" target="_blank"><code>uvicorn</code></a> - for the server that loads and serves your application. This includes `uvicorn[standard]`, which includes some dependencies (e.g. `uvloop`) needed for high performance serving. * `fastapi-cli[standard]` - to provide the `fastapi` command. * This includes `fastapi-cloud-cli`, which allows you to deploy your FastAPI application to <a href="https://fastapicloud.com" class="external-link" target="_blank">FastAPI Cloud</a>. ### Without `standard` Dependencies If you don't want to include the `standard` optional dependencies, you can install with `pip install fastapi` instead of `pip install "fastapi[standard]"`. ### Without `fastapi-cloud-cli` If you want to install FastAPI with the standard dependencies but without the `fastapi-cloud-cli`, you can install with `pip install "fastapi[standard-no-fastapi-cloud-cli]"`. ### Additional Optional Dependencies There are some additional dependencies you might want to install. Additional optional Pydantic dependencies: * <a href="https://docs.pydantic.dev/latest/usage/pydantic_settings/" target="_blank"><code>pydantic-settings</code></a> - for settings management. * <a href="https://docs.pydantic.dev/latest/usage/types/extra_types/extra_types/" target="_blank"><code>pydantic-extra-types</code></a> - for extra types to be used with Pydantic. Additional optional FastAPI dependencies: * <a href="https://github.com/ijl/orjson" target="_blank"><code>orjson</code></a> - Required if you want to use `ORJSONResponse`. * <a href="https://github.com/esnme/ultrajson" target="_blank"><code>ujson</code></a> - Required if you want to use `UJSONResponse`. ## License This project is licensed under the terms of the MIT license.
