It wasn't so long ago that websites were islands, barely capable of communicating with the mainland. They were isolated brochureware, a place where the sun rose and set on static information that was hard-coded like a pina colada on a tropical postcard.

In the early days (we're talking the ancient realm of the 1990s), CORBA offered the first common object requests between systems. It was later followed by SOAP – a protocol that acted more like a shortwave radio that communicated data but didn't provide any instructions for how a response should be handled.

It wasn't until REST that APIs were fully in motion. It provided an architectural style that delivered precise information to endpoints but also instructions on how to consume the data (think CRUD functions that create, read, update or delete).

While SOAP was still good for more stateful, conversational operations, REST rolled like a wave across the web and application layers of the Internet. Today, over 70% of public APIs are REST or "RESTish," meaning... well, almost everyone is using it. Now, as GraphQL matures and the API landscape expands, a decoupled approach to building digital experiences is more of the rule and not the exception.

This is exactly why the headless CMS has exploded in popularity. And there are a lot of platforms to choose from.

If you're searching for a headless CMS, don't lose your head (sorry, we had to do it). We're here to help. 

In this article, we've assembled a list of solid solutions that offer a truly free experience. Fair warning: the word "free" means that a tier of a product is free forever. This often translates into a slimmed-down or limited entry with options to upgrade, but it's not a trial.

Before we dive in, a bit more about this hot category of content management systems.

What is a Headless CMS?

As the name implies, a headless CMS is a kind of backend content management system that separates or decouples the “body” – otherwise known as the content repository – from the presentation layer, often referred to as the "head." Content in a headless CMS is delivered through APIs, allowing it to be displayed across different devices and endpoints.

With traditional (or coupled) CMS platforms, the content management backend is completely tied to a website's front-end. This effectively limits content creators and developers just to the website pages and templates that are managed and rendered in the system itself. 

With a headless CMS, you are truly "channel agnostic." That means you can manage content via the JAMstack (JavaScript, API, and Markup) with different front-end static site generators using React or Vue. But the omnichannel only begins at the website layer: with a headless CMS, you can manage content on a wide range of endpoints, from digital signs to wearable tech to IoT devices. The possibilities are endless. 

Here are a few more key advantages of using a headless CMS:

  • Freedom and control: With headless, there are no predefined templates or designs and no tight coupling between business apps and the CMS itself. This allows you to choose whatever technology or framework you want for your front-end app.
  • Easy to use: Generally speaking, headless CMS platforms are much easier to deploy and less complicated to use. The more you integrate, the more complex things can get, but you start with something that's less cumbersome.
  • Rapidly integrate new channels: Unencumbered by the limitations of a traditional CMS, you can add new devices and endpoints with ease.
  • Single source: With a headless CMS, you have one platform to distribute all of your content from, giving you the ability to maintain standards and versions. 
  • API first: Purpose-built for APIs, a headless CMS is less resource-intensive and performs much faster.  
  • Secure and scalable: By decoupling the authoring and delivery layers, you can scale components separately while maintaining security.

Sounds awesome, right?

OK, so there are a few disadvantages to going headless. The big one: authors can't preview how their content appears in applications outside the CMS. This is something Preston So refers to as "digital orchestration" and the problem of headless CMS preview. It's a persistent issue across the headless horizon, particularly at the enterprise level – and it's forcing some platforms to rethink their models. There are also some limitations around analytics and personalization where a traditional CMS still has a leg up.

One more note: there are several "hybrid headless" platforms that provide both a coupled website CMS experience alongside a headless app (the best of both worlds, so to speak). These appeal to agencies or organizations with multiple apps that require different needs from their content teams within a single ecosystem. More on that in a future article.

Without further ado, here are the top free headless content management platforms you might want to evaluate:

When we said there are a lot of headless CMS platforms, we meant it. In fact, if you're poking around the JAMstack.org website, you'll find almost 100 different options. Trying to find the right one might be harder than drinking from a firehose. Hopefully, this list can help narrow down your efforts, but there are definitely some niche platforms that could fit the bill. 

In this post, we researched and analyzed the top free options that really deliver on the word "free." That means forever with limited strings attached. That said, some of the most reputable headless CMS options like Ghost CMS are open source and offer a free 14-day trial with starter plans for as little as $9 a month.

  • How easy is it to scale?
  • What does the developer ecosystem look like?
  • What sort of tools, SDKs, and off-the-shelf integrations does it come with?
  • If you're a marketer, is it low-code friendly?
  • From an API perspective, is it both REST and GraphQL ready?
