Plone

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.

• Rock-solid technology stack. The python/Zope/Plone stack is as solid as anything else out there.
• Highly customizable TTW, if needed, via the Zope Management Interface, or Diazo XSL-transform theme design.
• Good support from core developers, lots of solid add-ons which address just about any needs.
• Amazingly customizable workflow, permissions and security management.

Incentivized

• Bullets and formatting sometimes make it difficult to add text to an existing paragraph. The 'code' button is useful in those cases, but only to those who know html.
• Sometimes the pages don't save correctly and you use information.
• Uploading and displaying images is a bit too much work.

Plone has been used for more than ten years and it already has an interesting roadmap for its future. I do not know any other open source CMS with the same story of continuous evolution and security track. Interesting new features are added at each release and new modules are created continuously

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.

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.

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.

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

Well organized, professional training with good materials and instructions

Plone is much harder to learn then Wordpress. Development in Wordpress is learnt in day's, where development in Plone really takes years to get to the full depth. That said, once you're able to develop in Plone, is it a rock solid system, with readable code. In my experience Wordpress websites need to be updated so often, and the code feels bad organised. I have been building Wordpress websites, choosing Wordpress only when the client has almost no money. But I can never deliver the quality I want to deliver when using Wordpress. Plone does offer the possibility to deliver professional websites. As for Joomla, in the past I have done some Joomla development, but the whole CMS-paradigm could not settle in my brain. Being a web developer for over 15 years now, Joomla always felt contra-intuitive. Let alone the task of teaching this to my clients. Plone is now my only choice. It gives me a fast development-cycle, a user-friendly CMS and a rock stable and very secure system.

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

• We thought that tapping into the user/content management tooling of Plone would be a good and useful thing, however it turned out to be a major pain to tie into those parts of Plone.
• I wish we would have built the extra functionality completely outside Plone and found a way to integrate it. It would have been much easier.
