⚡ Benchmarks

HTTP requests per second (Linux x64)

WebSocket messages per second (Linux x64)

Socketify got almost 900k messages/s with PyPy3 and 860k with Python3 the same performance as Bun that also uses uWebSockets, Falcon at 35k messages/s and Falcon with PyPy3 improves into 56k messages/s, node.js manages 192k.

Runtime versions: PyPy3 7.3.9, Python 3.10.7, node v16.17.0, bun v0.2.2
Framework versions: gunicorn 20.1.0 + uvicorn 0.19.0, socketify alpha, gunicorn 20.1.0 + falcon 3.1.0, robyn 0.18.3
Http tested with oha -c 40 -z 5s http://localhost:8000/ (1 run for warmup and 3 runs average for testing)
WebSocket tested with Bun.sh bench chat-client
Source code in bench

Machine OS: Debian GNU/Linux bookworm/sid x86_64 Kernel: 6.0.0-2-amd64 CPU: Intel i7-7700HQ (8) @ 3.800GHz Memory: 32066MiB

Today socketify has get 30% performance hit due to workarounds between asyncio + libuv, so we will got even faster! See more info in this issue, Python3 and PyPy3 performance will improve when we migrate to HPy. In TechEmPower paintext benchmarks we are the fastest in active web framework for Python/PyPy with more than 2 millions of req/s, followed by Robyn with almost 1.2 million req/s and Falcon using meinheld with about 560k req/s.

📦 Installation

For macOS x64 & Silicon, Linux x64, Windows

pip install git+https://github.com/cirospaciari/socketify.py.git
#or specify PyPy3
pypy3 -m pip install git+https://github.com/cirospaciari/socketify.py.git
#or in editable mode
pypy3 -m pip install -e git+https://github.com/cirospaciari/socketify.py.git@main#egg=socketify

Using install via requirements.txt

git+https://github.com/cirospaciari/socketify.py.git@main#socketify

pip install -r ./requirements.txt 
#or specify PyPy3
pypy3 -m pip install -r ./requirements.txt 

If you are using linux or macOS, you may need to install libuv and zlib in your system

macOS

brew install libuv
brew install zlib

Linux

apt install libuv1 zlib1g

🤔 Usage

Hello world app

from socketify import App

app = App()
app.get("/", lambda res, req: res.end("Hello World socketify from Python!"))
app.listen(3000, lambda config: print("Listening on port http://localhost:%d now\n" % config.port))
app.run()

SSL version sample

from socketify import App, AppOptions

app = App(AppOptions(key_file_name="./misc/key.pem", cert_file_name="./misc/cert.pem", passphrase="1234"))
app.get("/", lambda res, req: res.end("Hello World socketify from Python!"))
app.listen(3000, lambda config: print("Listening on port http://localhost:%d now\n" % config.port))
app.run()

WebSockets

from socketify import App, AppOptions, OpCode, CompressOptions

def ws_open(ws):
    print('A WebSocket got connected!')
    ws.send("Hello World!", OpCode.TEXT)

def ws_message(ws, message, opcode):
    #Ok is false if backpressure was built up, wait for drain
    ok = ws.send(message, opcode)
    
app = App()    
app.ws("/*", {
    'compression': CompressOptions.SHARED_COMPRESSOR,
    'max_payload_length': 16 * 1024 * 1024,
    'idle_timeout': 12,
    'open': ws_open,
    'message': ws_message,
    'drain': lambda ws: print('WebSocket backpressure: %i' % ws.get_buffered_amount()),
    'close': lambda ws, code, message: print('WebSocket closed')
})
app.any("/", lambda res,req: res.end("Nothing to see here!'"))
app.listen(3000, lambda config: print("Listening on port http://localhost:%d now\n" % (config.port)))
app.run()

💼 Commercially supported

I'm a Brazilian consulting & contracting company dealing with anything related with socketify.py and socketify.rb

Don't hesitate sending a mail if you are in need of advice, support, or having other business inquiries in mind. We'll figure out what's best for both parties.

Special thank's to uNetworking AB to develop uWebSockets, uSockets and allow us to bring this features and performance to Python and PyPy

🔧 Forkers

❓ socketify.py vs japronto

People really want to compare with japronto, but this projects are not really comparable. Socketify is an active project and will be maintained over time with security updates and new features, japronto don't get any github updates since 2020 and don't get any src update since 2018, japronto don't support SSL, WebSockets, PyPy3, Windows or macOS Silicon, socketify will support Http3 and a lot more features.

And yes, we can be faster than japronto when all our features and goals are achieved, and we are probably faster than any current maintained solution out there.

❔ uvloop

We don't use uvloop, because uvloop don't support Windows and PyPy3 at this moment, this can change in the future, but right now we want to implement our own libuv + asyncio solution, and a lot more.

💫 CFFI vs Cython vs HPy

Cython performs really well on Python3 but really bad on PyPy3, CFFI are choosen for better support PyPy3 until we got our hands on an stable HPy integration.
