    The Joomla Project
    If your developers want to have some fun, Joomla offers the stability and friendliness to do custom coding. Certain marketing initiatives require us to get "cute" with the interface, and Joomla allows for that a bit easier than WordPress (and definitely easier than sites like Squarespace). The security of Joomla is also always a plus.

    Supernova is the best documentation platform on the market, having tested numerous alternatives, including the more popular zeroheight, Knapsack, etc. It's ideal for low-code solutions for brand guidelines and detailed component documentation. Their automated exporter pipelines are the icing on the cake, enabling them to pull what you see in Figma and push it directly into your codebase.

    Pros
    The Joomla Project
    • Security. Its got many new features in the new Joomla! 4 which make the already good security even better. I like the ability to use my Yubi keys to log in with the new webauth standard, I don't think any other CMS has that built in
    • W3C Accessibility Guidelines (WCAG) 2.1 (with AA compliance)
    • Really good SEO that gets our sites to the top of the search engines again without the need for any extra things
    • Speed, it gets a really good score (100%) in the google lighthouse on our server, can't beat that

    Cons
    The Joomla Project
    • Because Joomla's user community is smaller than WP, it lacks as many choices from 3rd party developers, meaning it can be a little more difficult to find the right extension for what you need to accomplish
    • Along the same vein, most of the best 3rd-party software for Joomla! is paid
    • Simple features such as Add to Menu and Cache cleaners should be adopted as part of the Joomla! core, though they are available as extensions
    • Joomla! could use a simpler and easier URL rewriting process

    • Difficult to sync large files (more of a Figma problem).
    • Restrictive paid tiers.
    • Redundant features.

    I gave it a rating of 10 because I just love how Joomla! works, how it is set up and how it handles many users. Also it is very fast, and there is no overload on the MySQL database or servers ever.

    Usability
    The Joomla Project
    Joomla! 3.x is easily installed either manually or via a script provided by your host. It contains most of the tools needed to begin creating websites right from the start. Those features that it doesn't have are easily installed via links and buttons from the thousands of extensions available in the community

    It is occasionally buggy, but nowhere near as buggy as zeroheight.

    Performance
    The Joomla Project
    Today's Modern Joomla performs very well and is robust and durable. The pages load faster than they ever did in the past and Modern Joomla's integration into other software or systems has become seamless. Modern Joomla sites will last long and will stay running forever.

    The Joomla Project
    Between the core Joomla developers who are excellent at answering questions and providing support, you have a whole community of developers who work with Joomla and are happy to help fellow developers out answering questions and supporting the Joomla project. Out of the many communities I am involved in for open-source software, Joomla's community is by far the best.

    The Joomla Project
    Joomla has gone through tremendous growing pains. It is now better than ever. But before, when it was going from 1.5-2.5, the templates and plugins would break over and over again. If you don't understand what Joomla was trying to do back then, you might have a bad attitude toward it. Today, those pains are over and things don't break like they used to during that time period.

    The Joomla Project
    We tested other platforms like WordPress, Magento and some local CMS. 
    But Joomla offered us better resources for generating content.
    Joomla is a CMS suitable for many types of projects, especially if you have several people editing content at the same time.
    It allows you to maintain visual standardization and offers many options for working with images.
    With its ability to control access to different articles, categories or even different components, it is a great tool, even if they are managed by different people.

    Supernova has best-in-class customer service. Our Figma library is a huge file and was unable to automatically sync with most platforms (including Supernova) - of all three platforms we tried, Supernova was the only one that actively assigned engineers to our case and offered a solution within a couple of days. They've been great partners.

    Return on Investment
    The Joomla Project
    • Joomla has reduced our costs of rolling out a new website because it uses less developer time and can be rolled out by individual users as needed.
    • Joomla has a lot of extensions and add-ons that make it easy to create and implement advanced solutions quickly.

    Supernova Screenshots

    Screenshot of the home dashboard, which offers a central overview of a design system's health at a glance — token, component, asset, and doc counts alongside live data pipelines connecting Figma, Storybook, and code destinations like Style Dictionary.Screenshot of the documentation editor, with inline commenting, review requests, and version drafts — letting teams document component usage guidelines (do's/don'ts) directly alongside live examples.Screenshot of a full semantic token library with values, dark-mode variants, and ready-to-use CSS variables — keeping design and code perfectly in sync across collections.Screenshot of usage analytics for design system documentation, used for tracking page views, sessions, and engagement trends so teams can see which patterns and guidelines get used most.
