Best headless CMS comparison

If you want to find the best headless CMS for a B2B site, it comes down to three different profiles: Sanity is the most flexible and developer-oriented, Storyblok is the most pleasant for marketers thanks to visual editing, and Contentful is built for large organizations that value governance and standardization over speed. None of the three is “the best”; it depends on who manages your content, how much you want to build and how fast you want to grow. This article puts them side by side on price, editor experience, developer-friendliness and B2B fit, so you can make a well-founded choice.

If you first want to know what headless actually means and when it makes sense, read the explanation of headless CMS. This piece assumes you already know those basics and now want to choose. If this belongs in a wider project, you will find the overview in our guide to having a B2B website built.

What does a headless CMS from Sanity, Contentful and Storyblok cost?

The three tools differ strongly in pricing model, and the entry price says little about your actual costs. Prices change regularly, so always check the current pricing page before you decide.

Sanity has a free plan with up to 20 seats and a paid Growth plan at around 15 dollars per seat per month, with a custom Enterprise plan. It also charges based on usage, such as API requests and bandwidth. Storyblok starts with a free Starter plan for one user, a Growth plan of around 99 dollars per month with a few seats, a higher Growth Plus plan, and custom Premium and Elite plans for larger teams. Extra seats cost a fixed amount per month. Contentful offers a free plan for up to 10 users, a Lite plan in the region of 300 euros per month, and above that only Enterprise on request.

The most important difference sits in the step up. With Sanity and Storyblok you scale relatively gradually along with seats and usage. With Contentful there is a large gap between the free plan and the next paid plan, and after that Enterprise straight away. For a small B2B team this can mean you land in a considerably more expensive segment sooner than expected. So always budget with the number of people who really edit content and with your growth over two to three years, not with the free starting point.

Which headless CMS is the most pleasant for marketers?

For the people who manage content daily, Storyblok is usually the most accessible of the three. Storyblok offers a visual editor in which editors see the page as it will go live and can adjust components directly. That lowers the barrier for marketing and sales teams without a technical background who do not want to wait on a developer for every text change.

Sanity works with a customizable editing environment, Sanity Studio, that you can fully tailor to your needs. That is powerful, but the default experience is more structured and less “what-you-see-is-what-you-get” than Storyblok, unless your developers put in the effort to set up live preview well. Contentful is strong in structured content and reusable blocks, but the interface feels more businesslike and abstract to many editors; you think more in data fields than in pages.

For a B2B organization where marketers want to publish landing pages and case studies quickly themselves, this editor experience weighs heavily. A good editor reduces your turnaround time and your dependence on developers, and that translates directly into more content published faster, which can generate leads.

Which headless CMS is the most developer-friendly?

Sanity is often experienced by developers as the most flexible. The content is stored as structured data that you query flexibly through a dedicated query language, and the Studio is fully configurable in code. That gives a team a lot of control over data models and workflows, which is handy when you build something that deviates from standard patterns.

Storyblok is likewise easy to integrate and has SDKs for most frameworks, with the plus that visual editing is already built in, so developers need to set that up themselves less. Contentful is mature, well documented and predictable, with stable APIs; it is a safe choice in large teams, but feels less flexible and more pre-packaged than Sanity to some developers.

Important for your site performance: with all three you fetch content via an API and render it in your own frontend, for example in a modern framework. The speed of your site therefore depends mainly on how well that frontend is built, not only on the CMS. A headless setup makes excellent Core Web Vitals possible, but does not guarantee them; that remains construction work.

Which headless CMS fits a B2B organization best?

That depends on your team size, your governance requirements and your growth plans, not on a fixed winner. A rough rule of thumb does help.

If you choose mainly on the basis of a marketing team that wants to work independently and build visually, then Storyblok often fits well. If you have a strong development team and want a tailor-made content model with a lot of flexibility, then Sanity is usually the most pleasant choice. If you work in a larger organization with strict roles, compliance requirements and multiple teams that must publish according to fixed processes, then Contentful is best set up for that. For each of the three, keep in mind that processing data within the EU (in relation to GDPR) depends on the chosen plan and the region settings; check that explicitly if it matters to you.

For many Belgian B2B companies the honest conclusion is that a headless CMS only truly pays off with multiple channels, multilingualism, a large content catalogue or an in-house development team. If you have a clear site with a handful of pages and no technical team, then a traditional or visual platform is often cheaper and faster to launch, without you giving up on results. We are platform-agnostic and look first at your goals, team and budget before we recommend a tool, rather than defaulting to headless. You can read more about how we approach this on our page about website development.

How do you compare them concretely for your case?

Do not start with the tool, but with four questions about your own situation. Who will manage the content soon, and how technical are those people? How many people need a seat, now and in two years? How unique is your content model, and are you really building something custom or mostly standard pages? And to how many channels or languages do you need to publish?

If you answer those honestly, the choice often tilts to the right side on its own: many seats and a non-technical team push you toward Storyblok, a unique data model with strong developers toward Sanity, and a large organization with strict governance toward Contentful. Then test your shortlist against the current prices and build a small proof of concept with your own content; only then do you see how a tool really feels for your team.

The short summary

Sanity, Contentful and Storyblok are all three strong headless CMSes, but for different profiles. Sanity is the most flexible and developer-friendly, Storyblok the most pleasant for marketers through visual editing, and Contentful the most suitable for large, governance-driven organizations. On price, Sanity and Storyblok scale more gradually, while Contentful has a bigger step between free and paid. The right choice depends on who manages your content, how much you build and how fast you grow, and sometimes none of the three is needed because a simpler platform reaches your goal faster and cheaper.
