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!
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.

@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
- Streamed file processing
- http2
- No wheels for uvloop and httptools on Windows :(
