Creating and publishing high-quality content definitely helps businesses grow, reach new customers, and provide them with a superior digital experience. On the other hand, crap content can even turn buyers away from your business.
In this regard, in 2021, in the world of COVID-19, when the Internet began to live an even more active life, and online sales jumped several times, a new life began for CMS solutions. In fact, according to a report by MarketWatch, the CMS industry market size is projected to grow from USD 62.4billion in 2020 to USD 116.2 billion by 2025, at a CAGR of 13.3%.
In 2021, we also see a trend towards more and more active use of headless CMS, which allows companies and developers to deliver and manage content as quickly and conveniently as possible.
But with so many headless CMS options out there, it’s very difficult to find the right solution for a specific use case.
In this article, you will learn what a CMS is, the difference between headless and traditional cms, we will give examples of how and when it is advisable to use headless cms, and also consider how to choose headless cms. We’ve also compiled a list of the best headless cms on the market, so you can compare them, see features, and finally choose the best headless cms that fit your needs.
What are headless cms?
But first, let’s figure out what is headless cms?
Head = Static codes on the frontend, therefore, content can be displayed on just one device.
The term “Headless” means no front-end part. Accordingly, the headless CMS includes a back-end, a database, and an API that can be called to distribute content.
Publishing content via API allows you to deliver content to any device, browser, or application. This is the main advantage – you do not need to build the backend operation with the frontend for only one source.
In addition, there is no requirement for any hosts. Therefore, maintaining headless CMS is easier than non-headless CMS. This leads to improvement of the workflow and collaboration.
To some extent, headless CMS is a division of decoupled CMS. Decoupled means that the front-end and back-end are managed separately. In a decoupled system, when content is created and edited in the backend of a website, it is transmitted through an application programming interface (API) and then published in the frontend of the website.
How headless CMS work
Let’s now figure out what exactly is under the hood of headless cms and how it all works.
Without a front-end content delivery layer and no content authoring interface, a headless CMS is like a repository of content that is accessed via a REST API or GraphQL API. As a result, the content inside the CMS is no longer tied to a particular template or delivery layer. Instead, it’s free to be sent to any channel or device using APIs.
This architecture means that data can be transferred to any part of the network after a request has been made to the repository using the API. This does create advantages for publishing across channels, but it can also create issues for non-technical users.
While a decoupled system does have a front-end system, headless cms mean that marketers and non-tech people face certain challenges in presenting content to users. In headless cms, you will not find preview or WYSIWYG editors, which imposes certain difficulties.
Difference between a Headless and a Traditional CMS
We have prepared a small table in which to compare Headless and Traditional CMS.
|Features||Traditional CMS||Headless CMS|
|Hosting & delivery||In-house||In the cloud|
|Security||A traditional web server is easy to hack||Backend issues have no effect on the frontend. Might be some trouble if you lock your content to SaaS headless CMS services|
|Performance||Might be some difficulties with performance||Good performance due to architecture|
|Costs||Cost-effective because most traditional CMS is open-source with a good ecosystem of cheap hostings||Less cost-effective if you use SaaS headless cms|
|Customization||Difficult to customize but there are ready to use plugins that can help with some limitations||Easy to customize and very flexible|
|Scalability||Hard to scale||Can be easily shared through different platforms|
Why and when to use headless cms?
In short, we recommend using a headless CMS in the following cases:
- When scalability is one of the main issues for your blog;
- When you want to deliver content to multiple channels and platforms. If your business model is built around omnichannel content delivery and your content is available across multiple devices and platforms, then going headless over a traditional CMS is definitely a good choice;
When Not to Use Headless CMS:
- When your business model is one small website and you’re not planning any frequent or major updates, e.g. if you are running a single website populated with static content that changes infrequently, there might not be a lot to achieve with a headless CMS;
- When you don’t need separate channels except for website;
Also, before deciding whether to use a headless CMS, you should honestly ask yourself and your team do we need a headless CMS?
Honestly, no one but you can answer that question. Right now headless CMSs are considered future-proof mainly because of a clear distinction between the content and presentation. But only understanding your short and long-term goals will help you choose the right content management system for your business needs.
So should you always choose a headless CMS over a traditional, monolithic CMS? No.
So in summary, should you always choose headless CMS over traditional? The short answer is no of course.
There are certain benefits and downsides to choosing a headless CMS. But there are definitely use cases where it makes more sense than going with the traditional CMS. Below we’ve highlighted just a few of these.
As with any technology, there are certain benefits and downsides to using headless CMS. But definitely, nowadays more and more use cases appear when the use of headless CMS becomes justified. Thus, the decision of Headless CMS vs. Traditional CMS depends on your needs and how you are going to use it. Above were some common use cases, but this list is incomplete since you always have to decide for yourself based on your resources and needs.
Pros and Cons of headless CMS
- Compatible and Flexibility: You can deliver your content whenever you want;
- Security: As the content publishing environment isn’t accessible from the database, using this will prevent malware attacks;
- Scalable: since the front end and back end are separated, there is no separate time needed for maintenance. This allows you to customize your website anytime without having to compromise the performance;
- Faster time-to-market: You and your developers can test various hypotheses very quickly;
- No need to learn specific development languages.
- You need DevOps: you need a team to manage your content infrastructure and all the frontends you’re using to deliver content to different channels;
- Added development costs;
- Limited features for content creators;
- No content previews: and it is very difficult for marketing teams to edit content.
Is a headless CMS secure?
A question that worries a lot of people is – are headless CMS safe? Unfortunately, traditional CMS is not that good at this point.
When choosing a headless CMS, you should first look at what technologies they use out of the box. The standard is to use OAuth2. Also, since headless CMS actively uses APIs, they should follow API security best practices.
How to Choose Headless CMS?
When choosing from numerous headless CMS, pay attention to the following questions:
- Find out how your marketing department works and its objectives. How they deliver content and what features they need.
- Pay attention to the developers too – ask their opinion.
- Costs: Very few CMS are free (and we have a few here). Knowing what options are available and how far the tiers scale-up will help you plan ahead.
- Can you scale content without falling off a price cliff?
- How does the product manage files and image assets?
Best Headless CMS
Disclaimer: Flatlogic Web Application Generator
This article was written by the Flatlogic team. At Flatlogic, we also developed a kind of headless cms – Flatlogic web application generator. With the help of Flatlogic, you can build a content management system based on different technologies and different designs, get the source code for yourself and then customize it as you like and host it wherever you like.
It works simply:
- You choose your preferred technology stack: React, Vue, Angular, Laravel, Node.js, MySQL, PostgreSQL;
- Choose your preferred design;
- Define the database schema;
- Generate your cms and get the source code.
An important point is that before you can download the project code, you can view it in your personal account.
Another advantage of the Flatlogic Web Application generator is that with our scheme editor you can create not only different types of data, but also create relationships between them.
Strapi is an open-source Node.js headless content management system, which means that the entire codebase is available on GitHub and thrives on contributors. Strapi generates a working RESTful API or uses GraphQL for developers in minutes after installation. Data is made available through a customizable API. It’s important to note that Strapi is a self-hosted, not a SaaS content management system. The company will introduce a hosted version in the near future.
The primary goal of Strapi is to build a solid API while offering an intuitive admin panel. While Strapi has capabilities to ease the task of managing user sessions and applications, users have encountered occasional problems with the drag-and-drop interface and array data types.
Strapi allows you to define the content-type structure that you want, with the ability to define categories such as Text, Date, Media, Password, Relation, and Number. Apart from this, you can also edit the API code to personalize it even further.
Strapi also comes with auto-generated documentation, framework integration, and available plugin ecosystems.
TL;DR – Setting up a new project with Strapi is super easy and fast, API creation is fast and very customizable.
- Built-in support RESTful and GraphQL APIs;
- Good admin panel for content editors, fully customizable;
- Good plugin ecosystem;
The biggest drawback with Strapi is the pricing model itself. The free version only supports a limited number of users and roles — and it looks like the Enterprise edition will be the premium version that unlocks wider support.
The other problem is that relationships in the database still work not as expected. There are no built-in tools for migration data. There is no 2FA. It does not delete automatically unnecessary tables and columns from the database. Typescript is not supported, but we are in 2021.
Storyblok is a visual editor for content teams. Storyblok is a pure headless SaaS CMS. This makes it easier for editors to make changes themselves, in a similar way to traditional website builders.
