Sanic

Sanic is a Flask-like Python 3.5+ web server that's written to go fast. It's based off 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 a 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.

Server	Implementation	Requests/sec	Avg Latency
Sanic	Python 3.5 + uvloop	29,128	3.40ms
Wheezy	gunicorn + meinheld	20,244	4.94ms
Falcon	gunicorn + meinheld	18,972	5.27ms
Flask	gunicorn + meinheld	4,988	20.08ms
Aiohttp	Python 3.5 + uvloop	2,974	33.49ms

Hello World

from sanic import Sanic
from sanic.response import json

app = Sanic(__name__)

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

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