Unicorn Reviews

Unicorn vs. Puma vs. Passenger: which app server is right for you?
Puma and Passenger are equipped to handle slow clients. Unicorn cannot help with slow clients by itself: requests go directly to a worker process. Unicorn doesn't hide this. The Unicorn docs clearly state: "You should not allow unicorn to serve clients outside of your local network". However, you can get around by using Nginx as a reverse proxy and letting it buffer client...

  • Simplify Web App Development: Code Lite, Create Big!
    And Streamlit itself so far does not support Gunicorn, so its vertical scalability is limited. - Source: dev.to / about 2 months ago
  • Build a Vite 5 backend integration with Flask
    It's also worth mentioning that this Flask application is not production-ready. At the very least, you'll want to put an application server like Gunicorn in front of it (example in my repo). You'll also want to use a web server like NGINX to serve assets, or use a combination of WhiteNoise and a CDN to deliver assets. - Source: dev.to / 2 months ago
  • Improving upon my OpenTelemetry Tracing demo
    Every time I started the Flask service, it showed a warning in red that it shouldn't be used in production. While it's unrelated to OpenTelemetry, and though nobody complained, I was not too fond of it. For this reason, I added a "real" HTTP server. I chose Gunicorn, for no other reason than because my knowledge of the Python ecosystem is still shallow. - Source: dev.to / 3 months ago
  • Setting up Django in a Better Way in 5 Minutes and Understanding How It Works
    The static files are managed with whitenoise, Gunicorn is used for the WSGI server and Sentry is used for error monitoring and reporting in production. - Source: dev.to / 5 months ago
  • Build a CI/CD pipeline for Flask apps using GitHub Actions
    Now, we can create the Procfile for Heroku. The Procfile contains the command that will be run once the application is deployed on Heroku. You can do this by creating a new file named Procfile and pasting the following command. We will be using Gunicorn to run the application instead of the default Flask server. - Source: dev.to / 6 months ago
