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.

## 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.

| Bottle  | gunicorn + meinheld |       13,596 |      7.36ms |
| Flask   | gunicorn + meinheld |        4,988 |     20.08ms |
| Kyoukai | Python 3.5 + uvloop |        3,889 |     27.44ms |
| Aiohttp | Python 3.5 + uvloop |        2,979 |     33.42ms |

## Hello World

```python
from sanic import Sanic
from sanic.response import json

app = Sanic()

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

app.run(host="0.0.0.0", port=8000)
```

## Installation
 * `python -m pip install sanic`
