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.
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. Contributions are welcome!
If you have a project that utilizes Sanic make sure to comment on the issue that we use to track those projects!
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.

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)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
- http2
- No wheels for uvloop and httptools on Windows :(
