7 Best Free Headless CMS Platforms in 2026 (Free Tiers Compared)

Search "free headless CMS" and you'll get back a wall of marketing pages, every one of them claiming their product is free. Some of them mean it. Many of them don't. The reality is that "free" in the headless CMS world covers a wide spectrum: from genuinely unlimited open-source software you run yourself, to SaaS plans that are free right up until you actually try to use them for something real, and then they quietly stop working until you enter your card details.

The problem with picking the wrong one is not just that you'll eventually have to pay. It's that you'll spend days integrating a platform into your project, writing content, configuring schemas, and building your frontend before you hit a wall. Migrating away from a headless CMS once your content model is established is painful, so picking thoughtfully up front saves a lot of that pain.

Here is a straightforward comparison of the platforms that are actually worth your time to investigate further. We'll cover what's actually free, what the real limits are, and which one is the best match for your project and team size.

What "Free" Actually Means for a Headless CMS

Before looking at individual platforms, it helps to understand that "free" means two different things in this industry, and confusing the two is where most of the frustration originates.

The first type is open-source software. Tools like Strapi (self-hosted) are free in that their licenses cost nothing. You can download the software, run it on your own server, and use it indefinitely without paying the vendor anything. However, that doesn't mean it's free to operate. You still need a server, which costs money each month, and you still need to handle backups, security patches, and uptime monitoring yourself, or pay someone else to do it.

The second type is a SaaS free tier, which platforms like Prismic, Sanity, Contentful, Storyblok, and Hygraph offer as hosted services. They manage the infrastructure for you, and they offer a free plan that lets you get started without paying. However, these plans have hard quotas, and when you hit them, one of two things happens: either your service stops responding entirely until the next billing period, or you get prompted to upgrade.

And, as with a lot of tech choices, the correct answer to which one of these is right for you depends on your situation and requirements.

The Best Free Headless CMS Platforms in 2026

1. Prismic

Best for: solo developers and small teams building marketing sites.

Prismic is a hosted headless CMS that pairs a structured content model with a visual page builder called Slice Machine, with a strong focus on component-based development. The free tier is usable for individual developers, though the single-user restriction makes it less than ideal for those requiring collaboration.

Free tier details:

• 1 user
• Unlimited documents and content types
• 4 million API calls per month
• 100GB CDN bandwidth per month
• 2 locales
• Visual page builder and Slice Machine included

Free tier reality check:

Four million API calls sounds like a lot, but it depends entirely on your traffic and how your frontend fetches content. If you're building a statically generated site that pulls content only at build time, you may never come close to that limit. If you're fetching content client-side or running many preview requests, you can burn through it faster than expected. Critically, there are no overage allowances, so while you won't be billed for exceeding the limits, your site may stop working if you hit them.

Paid pricing:

The Starter plan begins at $10/month per repository (billed annually).

2. Sanity

Best for: teams needing flexibility and real-time collaboration.

Sanity is built around a concept it calls the Content Lake, a hosted data store that decouples your content from any particular frontend or rendering strategy. The schema is defined in code, making it highly flexible and version-controllable. It supports both GROQ (its own query language) and GraphQL, and includes real-time multiplayer editing on all plans.

Free tier details:

• 20 included seats
• 2 datasets
• 10,000 documents per dataset
• 1 million API CDN requests per month
• 250,000 standard API requests per month
• Unlimited content types and locales
• 100GB asset storage
• 100GB bandwidth per month
• Real-time editing and multiplayer presence included
• Hosted Sanity Studio included
• No private datasets on the free plan
• No scheduled drafts
• No comments or task management
• No audit trail
• Community support only

Free tier reality check:

Twenty seats and unlimited locales make Sanity's free tier the most generous on this list. The 10,000-document limit per dataset is worth watching if you're building anything with a large content catalog, such as a news site or e-commerce product listings. It is also worth keeping in mind that Sanity add-ons can become expensive at scale, so review the full add-on catalog before committing to the platform for a high-volume project.

Paid pricing:

The Growth plan is $15 per seat per month, which includes 25,000 documents and additional API capacity.

3. Strapi

Best for: developers who want full control over their CMS.

Strapi is a fully open-source headless CMS that you install and run yourself. It generates a Node.js application with a configurable admin panel and a REST or GraphQL API based on the content types you define. Because it's open-source under the MIT license, you can run it on any server, modify the source code, and use it in any project without paying Strapi anything. There is also a managed cloud offering called Strapi Cloud.

Free tier details:

• Unlimited users and roles
• Unlimited content types and entries
• Unlimited API calls
• 200MB maximum asset size
• Full plugin ecosystem
• Full source code access and modification rights
• You are responsible for hosting, backups, uptime, and security

Free tier details (Strapi Cloud):

• 10GB storage
• 2,500 API requests per month
• 500 database entries
• The Cloud free tier is very limited compared to self-hosting

Free tier reality check:

The self-hosted option is as unlimited as your server is. If you're happy running a Node.js application on a VPS, then the operational cost is modest. The real cost is time: you own your own upgrades, security patches, and anything that breaks at 2 am. The Strapi Cloud free tier, by contrast, is too restrictive (500 database entries, 2,500 API requests) to be really useful for anything beyond exploration or a small prototype.

Paid pricing:

The Essential plan starts at $18/project/month for Strapi Cloud.

4. Contentful

Best for: teams needing a mature platform with a wide ecosystem.

Contentful is one of the oldest and most widely adopted headless CMS platforms on the market. It offers a polished content editing experience, a well-documented API, and a large library of integrations and community resources. The free tier is also notably generous with user seats, making it practical for small teams.

Free tier details:

• 10 users
• 2 roles (Admin and Editor)
• 2 locales
• 100,000 API calls per month
• 50GB content delivery bandwidth per month
• 50MB maximum asset upload size

Free tier reality check:

Ten users make this free tier usable by teams, which sets it apart from Prismic and Storyblok. However, the 100,000 API call limit is lower than Prismic's or Sanity's, so high-traffic sites may run into issues. One thing worth noting, however, is that the step up to the next paid tier ($300/month) is a significant jump in price.

Paid pricing:

The Lite plan starts at $300/month.

5. Storyblok

Best for: teams that need a visual editor.

Storyblok is the only platform in this list that puts a visual, live-preview editor at the center of its product. Content editors can click directly on page elements to edit them, making it particularly appealing to marketing teams or clients who need to manage content without developer involvement. The underlying CMS is a standard headless API, so developers can still query content from any frontend.

Free tier details:

• 1 team member seat (up to 2 total, with additional seats at $15/month each)
• 1 space (project)
• 20,000 maximum stories
• 2,000 maximum assets
• 100,000 API requests per month
• 100GB monthly traffic
• 2 locales
• 500MB maximum asset size
• Visual editor included
• No GraphQL access
• No SEO meta tags or story scheduling
• No uptime SLA
• 1-day activity log retention

Free tier reality check:

The visual editor is genuinely useful, and it's available on the free tier. But the restriction to a single user makes it impractical for any team, and the absence of GraphQL on the free plan is a significant gap if your app needs it. The 100,000 API requests per month is also amongst the lowest in this list.

Paid pricing:

The Growth plan starts at $99/month.

6. Hygraph

Best for: GraphQL-first teams.

Hygraph (formerly GraphCMS) is built around GraphQL from the ground up. Every content model you define automatically generates a typed GraphQL schema, and the API is GraphQL-only. This makes it a strong choice if your frontend already speaks GraphQL or if you want a strongly-typed API without any additional schema configuration. It also supports content federation, which lets you combine data from multiple sources into a single GraphQL layer, though that feature is only available on paid plans.

Free tier details:

• 3 seats
• 2 standard roles
• 1000 content entries
• 2 locales
• 10 components
• 20 models
• 500,000 API calls per month
• Unlimited asset storage
• 50MB maximum asset upload size
• 100GB asset traffic
• Rate limit of 5 uncached requests per second
• No scheduled publishing
• No remote sources (content federation)
• No SLA

Free tier reality check:

Five hundred thousand API calls per month is a generous allowance, as is the unlimited asset storage. However, the 1,000 content entries limit is the most restrictive hard cap on this list. If you're building anything beyond a small site or portfolio, you'll likely hit it. And, when you do, the next step up is the Growth plan at $199/month, which is a significant jump.

Paid pricing:

Growth plan is $199/month.

7. Decap CMS (formerly Netlify CMS)

Best for: Git-based workflows and statically generated sites.

Decap CMS takes a fundamentally different approach to the other platforms in this list. Rather than storing content in a hosted database, it stores everything as files in a Git repository. When an editor makes a change through the Decap CMS interface, that change becomes a Git commit. This means your content history is your Git history, your content backup is your Git remote, and your content access control is your Git permissions.

Free tier details:

• Completely free and open-source under the MIT license
• No user limits
• No API call limits
• No storage limits (limited only by your Git repository)
• No hosted service to pay for
• Works with any static site generator or framework that stores content in Git
• No hosted option: you must deploy it yourself alongside your site

Free tier reality check:

Decap CMS is free with no usage-based ceiling, but the "no hosted option" is a real constraint. It's also maintained by volunteers, so there is no commercial support structure and no roadmap guarantee. Overall, for a small personal site or a developer-led project with Git already a core part of the workflow, it's an excellent choice. However, for a team with non-technical content editors or a project that needs to scale or guarantee uptime, the lack of infrastructure management and support options might be a considerable gap.

Paid pricing:

None. Decap CMS has no paid tier.

Hidden Costs of a "Free" Headless CMS

The pricing page is not the whole story. Several cost categories, like those below, don't appear in the plan comparison table, and they're worth considering before you commit to a platform.

Hosting and server costs. For self-hosted tools like Strapi, you need a server. A basic VPS or managed Node.js host starts at around $5 to $20 per month. That's not expensive, but it's not free either, and it scales with traffic.

Egress and CDN fees. Some platforms charge for bandwidth or CDN traffic beyond the free allocation. If your site has a lot of image-heavy content or has high traffic, these costs can add up in ways that aren't obvious from the headline pricing.

Plugin and integration fees. Some CMS platforms have plugin marketplaces where the plugins themselves cost money. Others integrate with third-party services (image optimization, search, translation) that have their own pricing. These are easy to overlook when evaluating a platform.

The support gap. Every platform in this list offers community support only on the free tier. That means forums, Discord servers, and GitHub issues. If you hit a bug or an outage on a Friday afternoon and your free-tier plan doesn't include any SLA, you're waiting for a community volunteer or a Monday morning response. For a hobby project or prototype, that's fine, but for a production site with real users? That's a serious risk with potentially costly implications.

Migration cost. If you build on a free tier and then outgrow it, switching to a different platform is expensive in both time and money. Your content model is in the CMS, your frontend is coupled to the API shape, and your editors have already learned the interface. Migrating away from all of this is often the largest hidden cost, and why it's worth spending some time at the start ensuring you get it right.

When to Upgrade From a Free Tier

Hitting the limits of a free tier is not a failure. It usually means your project is growing, which is a good thing. But it helps to recognize the signs before your site starts breaking rather than after.

The clearest signal is API quota errors. If your monitoring or your users start reporting content not loading, and the cause turns out to be an exhausted monthly quota, you've already left the problem too late. Most platforms provide usage dashboards, and it's worth checking them regularly so you can plan a tier upgrade before you hit the wall.

A second seat requirement is another reliable signal. If you're on Prismic's free tier and you hire a second developer or bring on a content editor, you immediately need a paid plan. Planning that upgrade in advance avoids the scramble of trying to onboard someone while your account is restricted.

Finally, if your project has real users with expectations of availability, an SLA starts to matter. No free tier comes with one. The moment that you need to guarantee uptime for a client or a paying customer, a free tier is no longer the right tool.

Closing Thoughts

"Free" covers a wide range of things in the headless CMS space. At one end, you have open-source software with no licensing cost but real operational overhead. At the other end, you have SaaS free tiers that are easy to get started with, but have hard limits that will eventually push you towards a paid plan.

The right choice depends on two things: whether you're comfortable managing your own infrastructure, and how closely your project's expected scale matches the limits of a given free tier. A solo developer building a personal site will find Prismic or Decap CMS more than adequate. A small team building a production application will probably find Sanity's free tier the best starting point. And, a developer who wants full control and is happy running their own server will find Strapi self-hosted the most flexible option of the lot.

For most projects, the free tier you choose now will not be the tier you're on in two years. Pick one that makes it easy to get started and then, when the time comes, easy to migrate upward.
