15 Best Open-Source CMS Platforms: Features, Integrations, and Custom Capabilities

Key Takeaways

Here’s a quick look at the best 10 CMS platforms, and their benefits and drawbacks that have set them apart.

What Is CMS Implementation and Why Is it Important

A CMS is kind of a central point for creating and managing web content. Teams can easily create, review, and publish updates on websites, mobile apps, or other platforms using a CMS. And there’s no need for custom work each time.

High-end CMS products also connect to DAM (data asset management) systems and marketing workflows to prevent the same content from getting reused. 

They also ensure a consistent look globally, among other uses.

One particular benefit is the real-time content editing and preview function that lets users see what their final work will look like prior to release. 

This reduces the effort required during production and approval. 

A CMS connects to your digital asset library so you don’t waste time updating and duplicating resources.

Why Use an Open-Source Headless CMS

Without open-source software and the ecosystems that support code development, companies would have spent approximately 3.5 times as much to create their own versions of software and platforms, or about $8.8 trillion.

An open-source headless CMS works with APIs to serve content to any device. While a regular, traditional CMS is bound to certain templates that cater to desktop and mobile browsers.

Classic CMSs need complex coding to show content on web browsers, while a headless CMS simply uses API calls to send content directly.

The market is moving so rapidly, and open source makes it easier for enterprises to be agile. The flexibility of open-source systems means companies can avoid being locked into proprietary vendors or systems. 

Companies can switch applications or change code to better suit business needs.

And companies value not only the flexibility of open-source software but its ecosystem as well. It’s basically about ensuring that we can build a thriving developer community that is able to innovate and push the boundaries of open-source technology.

Main Features of a Modern CMS Platform

When you decide on a CMS, the relevant question to ask yourself is, what are the goals of it? 
Is it selling products online, blogging, or providing services? 

No matter what your need is, these features must be present in your CMS platform.

1. Omnichannel Experience

The brands people engage with are just about anywhere they seem to be, from websites and mobile apps to social networks and email, you name it.

An omnichannel CMS can help you publish to all those touchpoints without making it seem like the same exact effort, many times. This means your users get the same flawless experience no matter what they are using.

2. Intuitive Dashboards

You should look for a CMS that has a feature rich backend dashboard, which makes site management easy to do. The majority of (source and paid) CMS options have plugins available that will drag real-time data, like online sales or user comments, to one place.

3. Mobile-Friendly Design

Google crawls websites to index and rank them based on its mobile version — with a smartphone agent. This is called mobile-first indexing.

If you’d like to maintain or even improve your position on searches, ensure that you choose a responsive design that works across all devices — mobile phones, tablets, and computers. Bad mobile experience can make users go somewhere else for services or products.

4. Integration Opportunities

Implementing some other functionality on your CMS website is a simple process with plugins. These integrations enable you to link other products or services. Offerings might also include business tools, payment solutions, carriers (shippers), and browsing off of other sites. WordPress, for example, has over 65,000 plugins.

If your site captures sales leads and is not tied into your customer relationship management (CRM) software, then those two systems need to be manually updated regularly.

5. Localization Support

If you want an international audience, you will have to communicate in their language. Your CMS needs to enable content across locales, which will allow you to provide the content and customer service in the reader’s native tongue.

A traditional CMS may need to duplicate content manually in different languages. This can delay the post, because content is pending at different moments.

6. Tools for Publishing and Editing Content

Many older or large CMS platforms depend heavily on engineering teams for even small content updates. Meanwhile, other CMS systems are so flexible that editors might feel overwhelmed. It's crucial to check what editing and publishing options are available, especially with visual building tools.

7. Social Media Integration Tools

A solid CMS can boost your social media presence with every post. Such platforms have built-in social media integrations for showcasing posts and photos on your site.

Connecting social media accounts to your CMS, either directly or through plugins, keeps your content fresh. For example, posts from Facebook can automatically be fed into your site.

If your CMS does not include social media integration, you’ll have to physically post content on each platform and have links to your social pages on your site for visitors.

8. Analytics and Reporting

A modern CMS should make processing content simple, even complex datasets. You also want to be able to view user activity across multiple interfaces for reporting. As that can help you gauge engagement rates, performance, conversion rates, etc.

The key here is understanding which content is performing well in terms of engagement on specific pages. So that you can refine your products to make them more appealing to potential leads.

9. User Access and Roles

Defining distinct user roles is always helpful in your CMS for setting up access. Usually, there is one or two people with open admin access. This reduces the potential for errors or security breaches. It also makes troubleshooting easier for when we have to figure out what happened.

Even if you are the primary user and editor, at some point you will probably want to bring in a content writer or web designer. Role assignments allow you to grant temporary access to new users for a specific project and then reassign the rights, which is quite secure and effective.

10. Basic SEO Extensions

If you’d like to optimize your site for organic marketing or lead-based sales, then you will want to focus on search engine optimization (SEO). Just posting on the web isn’t enough. 

SEO tools can scan your content for keywords, optimize images, and have other useful features to enhance the SEO potential of your site. For example, your CMS should enable you to customize the URL of every page rather than going with a default title.

11. Convenient Developer Tools

When selecting a CMS, consider how it supports your teams to prevent them from using separate, disconnected tools. A good CMS empowers content managers and editors to manage tasks independently, which saves developers time.

To support developers, it should provide tools like content migration features, a custom command line interface (CLI), and DataSync tools to reduce API calls.

12. Multilingual Plugins

Creating multilingual content that you can add in your CMS, your website becomes accessible to users worldwide. This will have a positive impact on your global SEO and increase conversions.

A number of open-source CMS options support multilingual plugins. These plugins are capable of translating your site automatically with the use of artificial intelligence.
