Awesome Versioning Build Status

A curated list of awesome ASGI servers, frameworks, apps, libraries, and other resources.

This list should help you keep yourself up to date with the most awesome ASGI projects and resources. You can watch releases on this repo to be notified about new entries. If you find anything missing, please contribute. ❣️

ASGI is a standard interface positioned as a spiritual successor to WSGI. It enables communication and interoperability across the whole Python async web stack: servers, applications, middleware, and individual components.

Born in 2016 to power the Django Channels project, ASGI and its ecosystem have been expanding ever since, boosted by the arrival of projects such as Starlette and Uvicorn in 2018.

Contents

Application frameworks

Frameworks for building ASGI web applications.

  • Asgineer - A really thin ASGI web framework, which includes support for long polling, SSE and websockets.
  • BlackSheep - BlackSheep is an asynchronous web framework to build event based web applications with Python. It is inspired by Flask, ASP.NET Core, and the work by Yury Selivanov.
  • Channels - Asynchronous support for Django, and the original driving force behind the ASGI project. Supports HTTP and WebSockets with Django integration, and any protocol with ASGI-native code.
  • Django - The web framework for perfectionists with deadlines. Has native ASGI support since version 3.0.
  • Falcon - The minimalist REST and app backend framework for Python, with a focus on reliability, correctness, and performance at scale. Native ASGI support since version 3.0.
  • FastAPI - A modern, high-performance web framework for building APIs with Python 3.6+ based on standard Python type hints. Powered by Starlette and Pydantic. Supports HTTP and WebSockets.
  • Guillotina - Full-featured ASGI-compatible REST application framework, designed for high performance and horizontally scaling solutions.
  • Pyotr - A server framework, as well as a client library, for serving and consuming OpenAPI-based Web services. Based on Starlette and HTTPX.
  • Quart - A Python ASGI web microframework whose API is a superset of the Flask API. Supports HTTP (incl. SSE and HTTP/2 server push) and WebSockets.
  • Responder - A familiar HTTP Service Framework for Python, powered by Starlette.
  • Sanic - Sanic is a Python 3.6+ web server and web framework that's written to go fast. It allows the usage of the async/await syntax added in Python 3.5, which makes your code non-blocking and speedy. Supports HTTP and WebSockets.
  • Starlette - Starlette is a lightweight ASGI framework/toolkit, which is ideal for building high performance asyncio services. Supports HTTP and WebSockets.
  • Tonberry - Tonberry is an ASGI framework that takes a class based approach to routing. Influenced by CherryPy but made compatible with asyncio and WebSockets.

Authentication

Packages for adding authentication and managing users in ASGI web applications.

  • asgi-auth-github - GitHub OAuth authentication for ASGI apps. Supports restricting to specific users or member of specific teams or organizations.
  • SessionAuth - Authenticate using sessions and cookies. (Shipped with Piccolo API, and requires Piccolo ORM.)
  • TokenAuth - Authenticate using tokens in request headers. (Shipped with Piccolo API, and requires Piccolo ORM.)

End-user applications

Real-world applications that run on ASGI.

  • Datasette - A tool for exploring and publishing data, including ASGI-compatible components and plugins.

GraphQL

Packages for building GraphQL APIs via ASGI.

  • Ariadne - A schema first Python library for implementing GraphQL servers.
  • Strawberry - A code first Python library for implementing GraphQL servers, inspired by dataclasses.
  • tartiflette-asgi - ASGI support for the Tartiflette GraphQL engine.

Monitoring

Packages for monitoring ASGI web applications.

  • New Relic ASGI - New Relic integration for ASGI applications. (Shipped with newrelic.)
  • opentelemetry-python - ASGI middleware and helpers for collecting application metrics via the (currently alpha) OpenTelemetry standard. Supports HTTP and WebSocket.
  • Scout APM Starlette - Scout APM integration with Starlette and Starlette-based frameworks. (Shipped with scout-apm.)
  • Sentry ASGI - Sentry integration for ASGI frameworks. (Shipped with sentry-sdk.)
  • timing-asgi - ASGI middleware to record and emit timing metrics.

Proxies

Packages for use when running ASGI web applications behind proxies, or proxying other servers via ASGI applications.

  • asgiproxy – Tools for building HTTP and Websocket proxies for ASGI.
  • ProxyHeadersMiddleware - Use X-Forwarded-Proto and X-Forwarded-For headers set by a known and trusted proxy to make client and scheme reference the connecting client (shipped with Uvicorn).

Real-time web

Packages for use when building real-time-capable ASGI web applications.

  • python-socketio - WebSocket clients and servers using Socket.IO. Includes an ASGI application wrapper.
