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.

Well suited to an organisation who wants a real presence and a superior customer experience when visiting your website. Very modern look and feel and is great for hosting videos and specialist graphics. It is hard to fault the product and it is up there amongst the best in the market

Pros
Portland Labs
  • 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).

  • A centralized UI to maintain multiple websites using a common entry point.
  • Page types and blocks that can be highly customized using .NET code, but at the same time allows checks and validations when being created by Marketing/Content Users.
  • A very good set of extra libraries/add-ons that allows to expand website functionality in a very short period of time (Content APIs, Personalization, A/B Testing, Social)

Cons
Portland Labs
  • 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.

  • On the technical side, Spire is all built on React Redux, so there's a React framework and then Optimizely built their own framework on top of that React implementation, which is, I'd say customized and non-standard. So learning that as a developer is usually a four to five month learning curve. So that is a con where it's not a standard React redux implementation.

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.

Since I work on the implementation side of things, and do not directly own licensing for Ektron CMS, I have to base this rating off of how I think it will be received or presented to customers looking to start a new site deployment. I try to remain CMS agnostic, though my specialty is with the .NET and Microsoft stack. Because of the experience I have working with Ektron, I tend to be more forgiving with the shortcomings as I am familiar with how to work around them or past them from experience. Being familiar with the community available also helps, as you become familiar with the best approaches to find solutions to your issues. Each product has it's ups and downs and all of them are only going to be as good as the company or development team implementing them can make them. This is EXTREMELY important to remember when choosing a CMS, as it can make or break your expensive investment.

Usability
Portland Labs
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.

The Opti CMS is pretty easy to use once you get used to it. Setting up the experience editor takes some time and difficult to follow and do in a group setting. We found working one on one or in smaller groups works better

Reliability and Availability
Portland Labs
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.

Unplanned outages or errors are fairly rare in our instance. And when there are issues, they're usually fixed fairly quickly

Performance
Portland Labs
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!

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.

I attended multiple trainings/tutorials early in the process. The vendor-supplied content about Optimizely was engaging for users/attendees (I often analyze training content, compliance programs, governance plans), which helps our OCM people by having good "word of mouth" about the product long before a rollout ever happens. I actually when the user-focused portion of the Optimizely Academy twice in 2022 to ensure I had a grasp on operability and to be able to support the training and OCM efforts

Ektron is one of the best solution for .Net platform. Over the years have improved the performance issues that the previous versions had. My only complain is right now you can't do Page builder pages if you choose to have a MVC architecture

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.

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.

Optimizely CMS is part of a more composable suite when it comes to DXPs. With that, some other systems like Sitecore Experience Platform are monoliths, which makes the development and maintenance of those products fairly complex (this includes system architecture). In our experience, Optimizely makes it simpler to implement solutions in a rapid manner and "tack on" additional products if needed as organizations grow and are able to leverage that functionality.

Return on Investment
Portland Labs
  • 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.

  • The positive is on ROI as we can get more done without needing to go through 3rd party or know Code to create and add content.
  • Workflows could use improvement. I don't know that there are workflows that I'm aware of.
  • Make it easier to connect to 3rd party software like Hubspot, Magento, email services, etc.
