Sanic is a Python 3.6+ web server and web framework that's written to go fast. It allows the usage of the

syntax added in Python 3.5, which makes your code non-blocking and speedy.

Sanic is also ASGI compliant, so you can deploy it with an

alternative ASGI webserver

Help and discussion board 

The project is maintained by the community, for the community. Contributions are welcome!

The goal of the project is to provide a simple way to get up and running a highly performant HTTP server that is easy to build, to expand, and ultimately to scale.


pip3 install sanic
Sanic makes use of ``uvloop`` and ``ujson`` to help with performance. If you do not want to use those packages, simply add an environmental variable ``SANIC_NO_UVLOOP=true`` or ``SANIC_NO_UJSON=true`` at install time.

.. code:: shell

$ export SANIC_NO_UVLOOP=true $ export SANIC_NO_UJSON=true $ pip3 install --no-binary :all: sanic

.. note::

If you are running on a clean install of Fedora 28 or above, please make sure you have the

package installed in case if you want to use

.. note::

Windows support is currently "experimental" and on a best-effort basis. Multiple workers are also not currently supported on Windows (see

Issue #1517 
_), but setting
should launch the server successfully.

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':'', port=8000)

Sanic can now be easily run using


.. code::

[2018-12-30 11:37:41 +0200] [13564] [INFO] Goin' Fast @
[2018-12-30 11:37:41 +0200] [13564] [INFO] Starting worker [13564]

And, we can verify it is working:

curl localhost:8000 -i

.. code::

HTTP/1.1 200 OK
Connection: keep-alive
Keep-Alive: 5
Content-Length: 17
Content-Type: application/json


Now, let's go build something fast!
