Concrete CMS vs. Joomla! vs. Plone

Suitable if you are part of small to large scale companies or web-houses which have PHP developers and frontend engineers with some budgets. [Also suitable if] you or your client want to build a website that requires some features or uniqueness [and needs] some customization and freedom. Additionally suitable if you want this project to be DevOps based project or if the project requires very tight security and is inside of a closed network.

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.

The larger your organization, the more appropriate Plone will be. This is not to say that Plone is a worse choice for small websites, only that the minimum investment for a Plone site is certainly higher than for other platforms. If you already use Plone for your site and are looking for a redesign or an overhaul, I would only advise switching to a different platform such as WordPress or Drupal if your organization is downsizing. For any other situation, Plone is the natural choice for your growth.

• As a dev, the Page object (coupled with page attributes, nav menus and page lists) makes structuring a website or web app a dream. The separation of page templates from page types also helps, the former being about layout while the latter is more conceptual.
• As an admin, you pretty much have as much control as the developers of the site decide to give you.
• The versioning system allows admins to roll changes back and work on changes before publishing them.
• The permissions system is exceptionally powerful, allowing roles and/or individual users to be included or excluded from each permission.
• The attributes system allows pages, files and users to be given custom properties of various types (e.g. text, image, colour).

• 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

• Plone is a folder-based system, organising content in a similar way desktop-users are doing for the last two decades. No need to teach non-tech customers some relational-database like paradigm for content management.
• Plone is secure. It is the most secure CMS you can get your hands on.
• Plone is flexible, and makes fast development easy.

• Allow end users to clear cache when updating pages.
• Needs a few more built in forms.
• The CMS is not multilingual by default. Even though I managed to 'hack' it so, it would be nice to have it included.
• It'd be nice to make use of custom PHP modules through shortcodes more straight forward. It seems the hooks are a bit contrived.

• 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

• Not everything is configurable or editable by Plone, and when you need to adjust or add custom pieces in, you need to deal with Zope. Zope has an ugly, confusing and difficult UI and structure as a backend.
• Using 3rd party products is difficult to do - there are a few different ways to get them installed, all of which take a bit of luck to get right.
• Building custom products for Plone is not fun. You've got to deal with an archaic framework to tie in that is not well documented (there is documentation about many things, but not great documentation and there are a lot of holes in the documentation).

Its a very solid, very consistent package that never lets you down or leaves you frustrated. It gets a 10/10 because its so much better than anything else currently available. It also gets a 10/10 because, even if not compared to others, it does not leave you wanting for features or functionality. It is an excellent piece of software that will answer almost every CMS need.

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.

We have critical systems running on Plone so will need it in the future.

Free to use since its Open source, so we don't have to worry about licence costs.

We know how to use and develop Plone and it has no limits.

I have used it on over 30 projects in the past 3 years and it's still a pleasure to work in. Doesn't always have all the answers, no CMS does, but I still find it very easy to use from prototyping to working to final project. Also there is no problem working on a localhost then moving to a live site, like there is with WordPress. It's my go to app in my CMS quiver.

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

Compared to the amount of Plone sites, users and customizations we have in our organization, the amount of support requests and training needed is really small.

The new user interface in Plone 6 is even better, it is super fast, has lots of different blocks for enhancing the page, has flexible layout system and is easy to extend with more features.

Since it's not tied to a central server (other than for authorizing updates and assigning licenses to specific sites), it's available pretty much 100% of the time.

Our Plone sites are very robust. We have critical systems on Plone and we have been running sites on Plone for over 20 years with very little unexpected downtime.

The site works extremely well, the front end flies, searches and form submissions are very fast indeed. The reason its a 9 not a ten? the back end can be a little slow at times, and this is unfair, because for the backend to be so amazing, it has to do a huge amount of work!

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.

Plone is very intensive in its operations, and if not configured well it can be slow. However it is designed and built with speed in mind and with proper use of coding, templates and caching can perform extremely well under high loads. It is capable of scaling to very high load availability environments with no specific coding requirements.

Concrete5 is open-source and has an incredibly strong, polite, and supportive community. You can get an answer to nearly anything you want to do with Concrete5 by googling for it, searching the Concrete5 discussion forums or stack overflow, or posting your question to the forum. Members are very courteous and do not look down on those with less knowledge. And answers are always quick, informative, and supportive.

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.

There are not too many Plone companies in the world. But the ones who are, are high level professionals

I have been participating Plone training and the trainers have always been professional. Materials were good and the instructions clear

It is good if you know Joomla! if not it can get a bit confusing

Well organized, professional training with good materials and instructions

Build off of an existing theme to speed up the creation of custom designed themed. Bootstrap is a good one but there are many others that are probably much simpler to build from than the Bootstrap one was. Make sure you host on a Unix/Linux server so you don't have to install PHP or MySQL separately. It's just smoother on those platforms.

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.

WordPress at the time was riddled with security breaches in the news and while Concrete5 was smaller (and therefore a smaller attack vector), after eleven years of use, Concrete5 has only had one published incident with an add-on that resolved within hours and with excellent communication. You can talk to the CEO and the CTO (or the rest of the team). They are very engaged and you're working with a small company of people who care, not a call-center with people just waiting to go home.

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.

Drupal: Plone is cheaper, so with Drupal is more complex to reach the required ROI. However, Drupal has a lower learning curve WordPress: For our necessities it has a more expensive learning curve than plone. Joomla, is easier to use. However, it have some issues on security and web content where Plone is much better

Plone has no limits. We have massive sites and can run them just fine

• Concrete5 is the customer-facing side of our business. It's where we host the site that potential customers see before they choose to purchase and create an account with us. We are able to keep that site clean, user-friendly, and with a lot of available options for customers to interact with thanks to Concrete5
• The ability to have multiple users and admins for the site means that we all members of our team can go in and create new content, fix or troubleshoot issues, and edit the site easily.
• Our CRM isn't directly integrated with Concrete5, so when customers go to make a purchase with us, they have to leave our Concrete5 site.

• 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.

• The impact Plone has had at the University of Oshkosh is as follows: this software allows student workers to learn about IT departments and CMS's in a user-friendly way. It gives many students great jobs that look great on their resumes.
• Since there are great training manuals for Plone, there is increased employee efficient in the workplace. Training doesn't take long, and if there's ever a question, the Plone manual is a great tool to refer to.
• If an employee using Plone quits, its easy to find someone to replace them with quick training and great resources.
