Implementations
===============
Complete or upcoming implementations of ASGI - servers, frameworks, and other
useful pieces.
Servers
=======
Daphne
------
*Stable* / http://github.com/django/daphne
The current ASGI reference server, written in Twisted and maintained as part
of the Django Channels project. Supports HTTP/1, HTTP/2, and WebSockets.
Granian
-------
*Beta* / https://github.com/emmett-framework/granian
A Rust HTTP server for Python applications.
Supports ASGI/3, RSGI and WSGI interface applications.
Hypercorn
---------
*Beta* / https://pgjones.gitlab.io/hypercorn/index.html
An ASGI server based on the sans-io hyper, h11, h2, and wsproto libraries.
Supports HTTP/1, HTTP/2, and WebSockets.
NGINX Unit
----------
*Stable* / https://unit.nginx.org/configuration/#configuration-python
Unit is a lightweight and versatile open-source server that has three core capabilities: it is a web server for static media assets, an application server that runs code in multiple languages, and a reverse proxy.
Uvicorn
-------
*Stable* / https://www.uvicorn.org/
A fast ASGI server based on uvloop and httptools.
Supports HTTP/1 and WebSockets.
Application Frameworks
======================
BlackSheep
----------
*Stable* / https://github.com/Neoteroi/BlackSheep
BlackSheep is typed, fast, minimal web framework. It has performant HTTP client,
flexible dependency injection model, OpenID Connect integration, automatic
OpenAPI documentation, dedicated test client and excellent authentication and
authorization policy implementation. Supports HTTP and WebSockets.
Connexion
---------
*Stable* / https://github.com/spec-first/connexion
Connexion is a modern Python web framework that makes spec-first and API-first development
easy. You describe your API in an OpenAPI (or Swagger) specification with as much detail
as you want and Connexion will guarantee that it works as you specified.
You can use Connexion either standalone, or in combination with any ASGI or WSGI-compatible
framework!
Django/Channels
---------------
*Stable* / http://channels.readthedocs.io
Channels is the Django project to add asynchronous support to Django and is the
original driving force behind the ASGI project. Supports HTTP and WebSockets
with Django integration, and any protocol with ASGI-native code.
Esmerald
--------
*Stable* / https://esmerald.dev/
Esmerald is a modern, powerful, flexible, high performant web framework designed to build not only APIs but also full scalable applications from the smallest to enterprise level. Modular, elagant and pluggable at its core.
Falcon
------
*Stable* / https://falconframework.org/
Falcon is a no-magic web API and microservices framework, with a focus on
reliability, correctness, and performance at scale.
Supports both WSGI and ASGI, without any hard dependencies outside of the
standard library.
FastAPI
-------
*Beta* / https://github.com/tiangolo/fastapi
FastAPI is an ASGI web framework (made with Starlette) for building web APIs based on
standard Python type annotations and standards like OpenAPI, JSON Schema, and OAuth2.
Supports HTTP and WebSockets.
Flama
-----
*Stable* / https://github.com/vortico/flama
Flama is a data-science oriented framework to rapidly build modern and robust machine
learning (ML) APIs. The main aim of the framework is to make ridiculously simple the
deployment of ML APIs. With Flama, data scientists can now quickly turn their ML models
into asynchronous, auto-documented APIs with just a single line of code. All in just few
seconds!
Flama comes with an intuitive CLI, and provides an easy-to-learn philosophy to speed up
the building of highly performant GraphQL, REST, and ML APIs. Besides, it comprises an
ideal solution for the development of asynchronous and production-ready services,
offering automatic deployment for ML models.
Litestar
--------
*Stable* / https://litestar.dev/
Litestar is a powerful, performant, flexible and opinionated ASGI framework, offering
first class typing support and a full Pydantic integration. Effortlessly Build Performant
APIs.
Quart
-----
*Beta* / https://github.com/pgjones/quart
Quart is a Python ASGI web microframework. It is intended to provide the easiest
way to use asyncio functionality in a web context, especially with existing Flask apps.
Supports HTTP.
Sanic
-----
*Beta* / https://sanicframework.org
Sanic is an unopinionated and flexible web application server and framework that also
has the ability to operate as an ASGI compatible framework. Therefore, it can be run
using any of the ASGI web servers. Supports HTTP and WebSockets.
rpc.py
------
*Beta* / https://github.com/abersheeran/rpc.py
An easy-to-use and powerful RPC framework. RPC server base on WSGI & ASGI, client base
on ``httpx``. Supports synchronous functions, asynchronous functions, synchronous
generator functions, and asynchronous generator functions. Optional use of Type hint
for type conversion. Optional OpenAPI document generation.
Starlette
---------
*Beta* / https://github.com/encode/starlette
Starlette is a minimalist ASGI library for writing against basic but powerful
``Request`` and ``Response`` classes. Supports HTTP and WebSockets.
MicroPie
--------
*Beta* / https://patx.github.io/micropie
MicroPie is a fast, lightweight, modern Python web framework built on ASGI for
asynchronous web applications. Designed for flexibility and simplicity, it
enables high-concurrency web apps with built-in WebSockets, session management,
middleware, and optional template rendering with method based routing.
Tools
=====
a2wsgi
------
*Stable* / https://github.com/abersheeran/a2wsgi
Convert WSGI application to ASGI application or ASGI application to WSGI application.
Pure Python. Only depend on the standard library.
