Sanic is a Flask-like Python 3.5+ web server that's written to go fast.  It's based on the work done by the amazing folks at magicstack, and was inspired by `this article <https://magic.io/blog/uvloop-blazing-fast-python-networking/>`_.

On top of being Flask-like, Sanic supports async request handlers.  This means you can use the new shiny async/await syntax from Python 3.5, making your code non-blocking and speedy.

Sanic is developed `on GitHub <https://github.com/channelcat/sanic/>`_. Contributions are welcome!

If you have a project that utilizes Sanic make sure to comment on the `issue <https://github.com/channelcat/sanic/issues/396>`_ that we use to track those projects!

Benchmarks
----------

All tests were run on an AWS medium instance running ubuntu, using 1
process. Each script delivered a small JSON response and was tested with
wrk using 100 connections. Pypy was tested for Falcon and Flask but did
not speed up requests.

Hello World Example
-------------------

.. code:: python

    from sanic import Sanic
    from sanic.response import json

    app = Sanic()

    @app.route("/")
    async def test(request):
        return json({"hello": "world"})

    if __name__ == "__main__":
        app.run(host="0.0.0.0", port=8000)

Installation
------------

-  ``python -m pip install sanic``

To install sanic without uvloop or json using bash, you can provide either or both of these environmental variables
using any truthy string like `'y', 'yes', 't', 'true', 'on', '1'` and setting the NO_X to true will stop that features
installation.

- ``SANIC_NO_UVLOOP=true SANIC_NO_UJSON=true python -m pip install sanic``
