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.
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.
Here are a few more key advantages of using a headless CMS:
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:
Agility is a cloud-native, API-First content management platform. Agility CMS's mantra is you shouldn't have to compromise, and they deliver on that with a wide range of best-in-class features.

And by being an API-first platform, developers aren't limited to a specific language or framework – meaning they can deliver content to any front-end with any coding language.
Agility CMS works seamlessly with most of the popular JAMStack frameworks such as Next.js, Gatsby.js, and you can deploy to any hosting environment you want with dedicated integrations via Vercel and Netlify.
Agility's Developer plan is free forever, and it is great for developers working on personal sites.
