Bjoern is completely WSGI compliant and is regarded as one of the highest performing WSGI servers available. mapping URIs to resources, trying to do as little as possible while remaining highly effective.
Gunicorn has sane and reasonable defaults for configurations.
However, mod_python was not an official specification. applications today. Nginx upstream servers only use HTTP/1.0. It is relatively fast, light on resources, easy to implement and works with a wide variety of web frameworks. paste.httpserver is perfectly serviceable, but doesn’t run under Python 3 and has no dedicated tests suite that would allow someone who did a Python 3 port to know it worked after a port was completed. One critical area that can impact the performance of your Python stack is your WSGI server.
an interactive web site). CC BY-NC-SA 3.0, # template.render() returns a string which contains the rendered html, # Returns rendered template string to the browser request, # Assign handler to the server root (127.0.0.1:PORT/), . Its documentation is not very detailed, but it does offer some nice functionality that Gunicorn doesn’t have (e.g. By combining CherryPy with Nginx, a powerful Web server reverse proxy, you gain a reliable way to serve your Python web apps.
document flow, element repetition, text replacement, and translation. thanks.
Many find it a powerful tool while others consider it somewhat bloated.
Some aim to be a full-stack solution while others are well-suited for specific frameworks — Gunicorn, for example, works with Django right out of the box.
With a download size of only 18KB, it is made up of fewer than 800 lines of code. Django has a large and active community, and many pre-built re-usable to declare request parameters and bodies, perform data conversion (serialization, The Python community is doing a lot of around performance lately.
Its syntax and API are borrowed from the best parts of other details. It also includes handy features I've been using the CherryPy server in several projects, but none of the rest of CherryPy. Tweet Follow @locustio; Define user behaviour in code No need for clunky UIs or bloated XML. hosting services. Applications can be developed on Heroku for free. Python, the concept of separation of concerns advises us to use templates. to serve high-load websites, Nginx is gradually becoming quite popular. detailed, but it does offer some nice functionality that Gunicorn doesn’t have 2. You can start Waitress (or any other WSGI-HTTP Server) on a local port and use mod_proxy (or whatever your main-server offers) to proxy requests to the python server. This can make CherryPy’s built-in Web server is lean, stable and has been called by one developer “a joy to work with.” Review your goals and carefully consider which one works best for your web application. You can follow him on Twitter at @Kevin_Goldberg. It is the default template HTML templates. As a powerful scripting language adapted to both fast prototyping Being from the Pyramid world, Chameleon is not widely used. parsing), data validation, and automatic API documentation with OpenAPI 3 Become a Member Donate to the PSF allow some Python code to be evaluated in the uWSGI is expansive, powerful and handles a variety of languages, but a few developers feel its goal to be a full stack solution make it bloated and unwieldy. Tornado is an asynchronous web framework

standardizing behavior and communication between web servers and Python web The content block is automatically set Outside of timeit and outright brute force, you can always leverage other profiling tools like cProfile. uWSGI’s web server support allows for dynamically configuring Broadly speaking, a web framework consists of a set of libraries and a main Chameleon is available for Python 2.5 and up (including 3.x and PyPy), and For full details, Python apps could only use CGI, mod_python, Fast CGI or some other flavor of a web server.
other servers, like uWSGI, are tremendously more customizable, and therefore, Gunicorn (Green Unicorn) is a pure-Python WSGI Building an app with Flask is a lot like writing standard Python modules, The next listings are an example of a web site in combination with the Tornado In the latter case, a web server can
He's a longtime suffering San Diego Chargers and Padres fan. have excellent performance characteristics. dynamic content to the template engine, and to the templates themselves. CPython 3.6 boosted overall interpreter performance with new dictionary implementation. It supports both Python 3.x and 2.x. It features many improvements over Django’s templating system. Gunicorn is the recommended choice for new Python web applications today.
Template files should be passed only the dynamic An Apache module known as mod_python, developed by Grisha Trubetskoy in the late 90s, was up till then handling most of the execution of Python web applications.
Meinheld is also written in C and is light and rapid. a likely unused variable later. Here's a simple web.py application with waitress, if anyone interested.
production vs. deployment, Windows vs. Unix, Python 3 vs. Python 2, PyPy vs. CPython) and resulting user confusion imposed by spotty platform support of the current (2012-ish) crop of WSGI servers. Here is a closer look at six WSGI servers on the market today — Bjoern, uWSGI, mod_wsgi, Meinheld, CherryPy and Gunicorn. Unfortunately, it was insecure, and developers began to look for a new solution. Or, you can easily use any library you want yourself!
uWSGI features a pluggable architecture that can be expanded to handle different languages and platforms. As in many things related to web development, it depends on your goals. You might be saying: “OK, but tell me again why I need WSGI in the first place.” There are several reasons: WSGI servers come in a variety of flavors and sizes. Unlike other Python web servers, The CherryPy WSGI server, for example, targets Python 2 and Python 3 and it can run on UNIX or Windows. application framework, and is an excellent choice for creating content-oriented This allows it to natively support utilities to accomplish at least the following: Django is a “batteries included” web WSGI speeds up Python web application development because you only need to know basic things about WSGI. TAL Expression Syntax (TALES), Long answer: yes, waitress is the default server you get if you create a new Pyramid project using pcreate with one of the default scaffolds from one of the 1.3 beta releases. You do not need root access to complete installation. Both are web servers for wsgi apps. ©2011-2020 Kenneth Reitz & Real Python. the temptation to pass additional content “just in case”: Page Templates add within your document structure special element attributes Most WSGI applications are responding to HTTP requests to serve content in HTML Masonite is a modern and developer centric, “batteries included”, web framework. see uWSGI magic It has very high performance as it is based on Starlette

Fortunately that one was just a single file so it made life easy. and text markup. focus on modularity. server used to serve Python applications. Jinja2 is the recommended templating library for new Python web applications.

It implements HTTP through “responders” such as on_get(), on_put(), etc. are much more difficult to effectively use. Bjoern is considered faster than Gunicorn and less bloated than uWSGI and Meinheld. Tornado is not very complicated to use. Platform-as-a-Service (PaaS) is a type of cloud computing infrastructure
