By Markus Backman

9th April, 2024

The world of Headless CMS is saturated with lots of jargon and buzzwords these days, and we think that is frustrating too. We get it. That's why we've made a compilation of the most common buzzwords, industry terms, definitions and acronyms right now in the Headless CMS landscape.

Maybe you are a decision maker considering to migrate your website content to a new Content Management System, but there's so many buzzwords making you confused while trying to make sense of things. Of course, you want to become familiarized with all the terminology first so you can make a decision with more confidence. This is exactly why we've made a CMS buzzword glossary like this for you, consisting of the most trending CMS related definitions, industry terms, and buzzwords we can think of.

First of all, what's a headless CMS again?

Unlike traditional CMSs, with a Headless CMS it doesn't matter how you create your front-end. They simply provide an API that can be used to fetch necessary content to your front-end of choice (website, mobile application). Your content is decoupled from the front end so to say.

We can think of so many reasons why you should use a Headless CMS. Probably the biggest advantage is that you can manage all your content and assets in one place, nice and tidy. Everything works faster and more efficiently that way. We believe that Headless CMS will soon become the de facto standard for CMS architecture.

AMP is optimized for mobile web browsing and intended to help webpages load faster.


This is where the magic happens between two software communicating. An API (Application Programming Interface) is essentially a system allowing several software to communicate with each other. Examples are social media bots and eCommerce transactions.

Agile Development

Instead of being just a technology, Agile Development is more of a project management method in software development. Actually, it's more of an umbrella term comprising continuous planning, testing, and integration of software solutions.

A/B Testing

Let's say you have designed two or more user interface features for your website, like a CTA button. You are not sure how any of the features will perform among your website visitors for your website. This is where A/B testing comes in, you test which of the variants perform the best. In practice, you have a system that shows the user on of the variants, randomly, and then over time, with the help of tools you can see which of them perform better.

Best of Breed

When you host your website on cloud-native, you get a modular service that is easy to scale up and down depending on website traffic demand. The website becomes highly scalable, flexible, and reliable working with.

CDN (Content Delivery Network)

Think about when you have a large website, with lot's of different content, features and functions here and there, a Content Delivery Network comes handy in this case.

It reduces latency and keeps the website fast.

Composable Architecture

Composable web architecture is another modern approach to organizing web systems. It simplifies web development by dividing complex systems into smaller, reusable components. To put it simply, every component is a building block that can be easily manipulated. Whether it is a user interface element, a business logic module, or a data service, you can combine and customize them to suit any business's unique needs. By combining best of breed components like this, you'll get a architecture with a high level of freedom, being easy to work with.

Content as a Service

The Content as a service (CaaS) is an approach for delivering digital content to customers. Imagine that you have a website, and you produce tons of content.

Headless CMS

When the components of a system are loosely coupled, it is less likely that the system will experience performance issues, even if it has several components.

Low Code

Low-code is a trending concept in software development that uses a visual approach to facilitate faster delivery of applications. The main idea is that minimal hand-coding is required to do things.

MACH (Microservices, API-first, Cloud-native, Headless)

MACH is another trending concept of a web architecture, utilizing best of breed technologies to deliver really good websites.
