Storyblok, Sanity, or Contentful? Which CMS To Choose in 2026

Choosing a CMS in 2026 is no longer a superficial technology decision. For most organizations, it is a strategic choice that affects how quickly teams can move, how well content scales across channels, and how much technical and organizational friction accumulates over time.

For CTOs, VPs of Engineering, and senior technical leaders, the CMS (Content Management System) has become a foundational layer of the digital platform. It influences frontend performance, developer velocity, content governance, search engine visibility, localization, personalization, and increasingly, how AI-driven workflows are introduced into content operations.

Despite this, many companies still approach CMS selection as a procurement exercise or a feature comparison. That mindset often leads to costly migrations, frustrated teams, and systems that feel outdated far sooner than expected.

This article provides a comprehensive, practical comparison of Storyblok, Sanity, and Contentful – three of the most frequently shortlisted headless CMS platforms in enterprise and scale-up environments – to help you choose the proper CMS for your organization in 2026 and beyond.

Why choosing the proper CMS in 2026 matters more than ever

First, we can’t talk about CMS without mentioning WordPress. It revolutionized self-publishing in the 2010s and still powers over 60% of websites that use a CMS, but it is no longer a realistic choice. WordPress has always prioritized ease of use over performance, and such accessibility is not a priority for enterprises and scale-ups competing in highly competitive markets.

With that said, the CMS market is growing. Market evaluations for 2025 placed the global CMS sector at approximately USD 35.16 billion, with a projected trajectory reaching USD 79.30 billion by 2033. This growth represents a compound annual growth rate (CAGR) of 10.72%, a metric driven by the transition from monolithic, "all-in-one" legacy suites to flexible, cloud-native solutions

In practice, there are more and more CMS options available, even for niche use cases. Which is great, but also makes finding the ideal fit harder.

Real-world consequences of choosing poorly

As a result, organizations are switching CMS platforms more frequently than before, often after only a few years. The reasons are rarely aesthetic. Teams usually cite slow publishing cycles, rigid content models, poor editorial experience, unexpected cost increases, or an inability to support new channels without significant workarounds. 

However, choosing a platform that does not align with team capabilities can lead to vendor lock-in, where migration becomes prohibitively expensive due to tightly coupled APIs or proprietary models. Scaling limitations may surface once content volume or delivery channels increase.

Also, CMS-related issues tend to compound. A slight inefficiency in content modeling becomes a blocker during localization. A minor performance issue turns into a scaling problem once traffic grows. Over time, the CMS shifts from being an enabler to a constraint.

In 2026, enterprise-ready CMS platforms are expected to support omnichannel delivery by default. Websites are only one output among many. Content increasingly feeds mobile apps, internal tools, digital signage, marketing automation systems, and AI-powered personalization engines.

This evolution is one of the reasons many companies are moving toward composable architectures, where systems are loosely coupled and independently scalable. 

Architectural Shifts: From Headless to Composable and Agentic Ecosystems

A headless CMS separates content management from content presentation. Content is created and managed in a backend system, then delivered via APIs to any frontend or channel that needs it.

Traditional CMS platforms tightly couple content with templates, themes, and rendering logic. That approach works for simple websites but becomes limiting as soon as organizations need flexibility, speed, or multi-channel distribution.

While the initial headless revolution decoupled the presentation layer from the content repository, the current paradigm is defined by composable architectures. 

This modular approach treats each component of the digital experience stack – the CMS, the Digital Asset Manager (DAM), the personalization engine, and the search discovery layer – as a "best-of-breed" service connected via APIs.

Modern enterprises must distribute content across a sprawling network of touchpoints, including traditional web browsers, mobile applications, IoT devices, voice assistants, and emerging spatial computing interfaces. Conventional systems often struggle with this diversity because they were built for single-use cases, typically supporting tightly-coupled websites.

A secondary architectural shift is the emergence of agentic commerce. In 2026, content is no longer consumed solely by humans; it is evaluated and acted upon by AI assistants and autonomous agents. For engineering leaders, this requires a "single source of truth" where content is stored as highly structured data to ensure consistency during Generative Engine Optimization (GEO).

Finally, the transition toward cloud-based deployment models is one of the most critical trends for 2026, as organizations seek the scalability and cost-efficiency required to manage vast volumes of multimedia assets and real-time customer data.

Headless CMS platforms align naturally with modern frontend development. Teams can use frameworks such as React, Vue, or Svelte without being constrained by CMS rendering rules, and deployments can occur independently of content changes.

From a business perspective, headless CMS platforms enable reuse and consistency. The same content can power multiple products, regions, or experiences without duplication. From a technical standpoint, they reduce bottlenecks and allow teams to scale independently.

Before we move to the platform comparison, one essential remark: WordPress can be deployed headless. But that doesn’t change the fact that it’s not the best fit for mature use cases, as it doesn’t offer many of the positives we’ll discuss below.

Storyblok overview

Storyblok is often positioned as the most editor-friendly headless CMS on the market, and that reputation is largely justified. Its design prioritizes usability for content teams while still offering developers the flexibility they expect from a modern CMS.

Storyblok: Core philosophy

At the heart of Storyblok is a visual-first philosophy. The platform is built on the premise that content editors should not have to imagine the final output. Instead, they should see it as they work.

This approach reduces friction between content, design, and development teams. It also shortens feedback loops and minimizes the risk of publishing errors caused by misinterpretation of abstract fields.

Storyblok: Key features

Storyblok’s Visual Editor lets editors preview content changes in real time directly within the CMS interface. The live preview is especially valuable for page-based content such as landing pages, campaign sites, and marketing-driven experiences.

Content is structured using reusable components defined by developers. Editors assemble these components into pages while staying within predefined design constraints. This model aligns well with modern design systems and component-based frontend architectures.

The platform also includes solid support for localization, versioning, and editorial workflows, making it suitable for teams operating across multiple markets.

Storyblok: Pricing structure

Storyblok uses a tiered pricing model based on usage, users, and available features. Entry-level plans are accessible for mid-sized teams, while enterprise plans scale with traffic, locales, and collaboration needs.

Costs are generally predictable, but, as with most headless CMS platforms, pricing can increase significantly as usage grows. Long-term forecasting is essential.

Storyblok: Best for

Storyblok is a strong fit for organizations with established design systems and content-heavy marketing needs. It works particularly well for multilingual websites where visual context matters and content teams need a high degree of autonomy without compromising layout consistency.

Sanity overview

Sanity (also called “Sanity Studio”) represents a very different philosophy. Where Storyblok focuses on visual clarity, Sanity focuses on flexibility and control, positioning itself as a content platform rather than a traditional CMS.

Sanity: Core philosophy

Sanity treats content as structured data first and foremost. Instead of providing a fixed CMS interface, it gives teams the tools to build a custom editorial environment tailored to their specific workflows.

This approach allows organizations to adapt the CMS to their processes rather than adapting their methods to the CMS. The trade-off is that teams must be willing to invest in configuration and long-term ownership.

Sanity: Key features

Sanity Studio is fully customizable using JavaScript, React, and Vue (by the way, we are early adopters of Vue). Developers define schemas, validation rules, and even the editorial interface itself. Such flexibility enables modeling of complex content relationships and domain-specific workflows.

Real-time collaboration is built in by default, allowing multiple editors to work on the same content simultaneously. Sanity’s query language, GROQ, provides fine-grained control over how content is retrieved and shaped.

Sanity integrates well with modern frontend stacks and is particularly popular in React-centric environments. Our article on choosing between Vue and React offers additional context for teams operating in this space.

Sanity: Pricing structure

Sanity offers a generous free tier, making it attractive for experimentation and early-stage projects. Paid plans scale with datasets, API usage, and collaboration features, while enterprise plans focus on security, compliance, and support.

When usage is modeled carefully, costs tend to remain predictable, even at scale.

Sanity: Best for

Sanity is best suited for technically mature teams that value flexibility and are comfortable maintaining a customized CMS setup. It excels in complex, content-rich products where content behaves more like structured data than pages.

Their developer-first approach is ideal for teams building scalable Vue development environments where clean abstractions and programmatic control are paramount.

Contentful overview

Contentful is one of the earliest and most established headless CMS platforms. Its positioning reflects years of enterprise adoption and large-scale use cases.

Contentful: Core philosophy

Contentful prioritizes reliability, scalability, and governance. It is intentionally opinionated, favoring consistency and predictability over extreme flexibility.

This philosophy appeals to organizations that value stability and process clarity, especially in regulated or highly structured environments.

Contentful: Key features

Contentful offers robust content modeling tools that allow teams to define explicit schemas and relationships. Editors work within well-defined structures, reducing ambiguity and errors.

Its API performance and global CDN are proven at scale, and large enterprises with high traffic and complex organizational requirements widely use the platform.

Contentful also provides a broad ecosystem of integrations with analytics, commerce, and marketing tools, making it a strong choice for large digital platforms. 

Contentful: Pricing structure

Contentful is typically the most expensive option among the three platforms. Pricing scales with entries, locales, users, and API usage, and enterprise plans require long-term budget planning.

In return, organizations receive strong SLAs, compliance support, and predictable operations.

Contentful: Best for

Contentful is well-suited for large enterprises with mature governance models and long-term digital roadmaps. It is often chosen by organizations that prioritize reliability and compliance over maximum customization.

Head-to-head feature comparison

On the surface, Storyblok, Sanity, and Contentful all tick the same boxes. They are API-first, cloud-based, and designed for modern frontend architectures.

The following comparison focuses on the areas that most often determine long-term success.

Content editing experience

The content editing experience is one of the most underestimated aspects of CMS selection. Even the best technical architecture struggles if content teams feel slow, constrained, or disconnected from the final output.

TL;DR: Storyblok is the most intuitive for editors, Sanity is as good as you build it, and Contentful prioritizes structure and consistency over visual context.

Storyblok is built around a visual editing paradigm. Editors work with real-time previews that closely reflect the live site or application. This preview dramatically reduces the cognitive effort required to understand how content changes will appear in production. For page-based content such as landing pages, campaign sites, or marketing-driven websites, this visual feedback shortens feedback loops and reduces publishing errors.

Sanity takes a more abstract approach. The editing experience revolves around schemas and custom interfaces created by developers. Such system allows organizations to tailor workflows precisely to their needs, but it also means the editor experience depends heavily on implementation quality. When designed well, Sanity can feel powerful and intuitive. When rushed, it can become confusing and intimidating for non-technical users.

Contentful offers a structured, form-based editing experience. Editors work within clearly defined fields and content types, which promotes consistency and reduces ambiguity. However, it provides limited visual context, requiring editors to rely more on conventions and documentation. This approach works well in organizations with formal processes and repeatable content patterns.

Developer experience

For development teams, the CMS becomes part of the application’s long-term architecture. Its flexibility, constraints, and extensibility directly affect how systems evolve.

TL;DR: Sanity offers the most control, Storyblok balances flexibility with guardrails, and Contentful optimizes for predictability and low architectural risk.

Storyblok offers a balanced developer experience. Its component-based content model aligns naturally with modern frontend frameworks and design systems. Developers define components and data structures, while the CMS enforces enough structure to prevent content sprawl. This makes Storyblok approachable for teams that want flexibility without building a fully custom CMS environment.

Sanity provides maximum control. Developers define schemas in code, customize the CMS interface, and model content exactly as required. This level of flexibility is particularly valuable in complex domains, but also increases responsibility. Teams must actively manage content governance, documentation, and long-term maintainability.

Contentful focuses on stability and predictability. Its APIs are mature, well-documented, and consistent across projects. While customization is possible, it is intentionally bounded. This reduces architectural risk and simplifies onboarding in large teams, though it can feel restrictive for developers seeking deep customization.

Performance and reliability

Performance and reliability often matter most once a platform is already live. These two factors rarely influence early demos but become critical as traffic, teams, and expectations grow.

TL;DR: Contentful leads at enterprise scale, Sanity excels in real-time scenarios, and Storyblok performs reliably for most content-driven use cases.

Storyblok delivers solid performance for most marketing and content-heavy use cases. Its global CDN and scalable infrastructure are sufficient for most organizations. In extremely high-throughput or near-real-time scenarios, live systems might require additional architectural considerations.

Sanity is particularly strong in real-time environments. Its live previews and real-time content updates enable collaborative workflows that require changes to propagate instantly. Performance is generally high, but efficiency depends on how queries and schemas are designed, placing more responsibility on the development team.

Contentful is widely regarded as the most battle-tested option at enterprise scale. Its infrastructure, uptime guarantees, and performance under heavy global load make it a common choice for organizations with strict SLAs and high business impact from downtime.

Collaboration features

Modern content workflows involve many stakeholders. A CMS must support collaboration without creating chaos.

TL;DR: Sanity enables real-time collaboration, Storyblok supports structured workflows, and Contentful emphasizes governance and approvals.

Storyblok provides role-based permissions, workflows, and approval processes out of the box. Combined with visual previews, this supports structured, asynchronous collaboration across distributed teams. It works particularly well when responsibilities are clearly defined.

Sanity approaches collaboration through real-time, multi-user editing. Multiple editors can work on the same content simultaneously, similar to collaborative document tools. Such flexibility can significantly accelerate content production, but it requires strong editorial discipline to avoid conflicts or confusion.

Contentful focuses on governance-driven collaboration. Its workflow and permission model support formal review processes, making it well-suited for regulated environments or organizations with strict content controls. While less dynamic than Sanity, it offers clarity and predictability.

Internationalization and localization

TL;DR: Contentful offers the most mature enterprise internationalization, Storyblok provides the best visual context for localization, and Sanity enables the most flexible – but complex – localization models.

Storyblok offers intuitive localization features with strong visual context. Editors and translators can preview localized content directly, making it easier to understand how translations affect layout and messaging. This is particularly valuable for marketing content across multiple regions.

Sanity provides powerful internationalization capabilities through flexible schema design. Teams can model locales in highly customized ways, supporting advanced localization logic. This flexibility is ideal for complex use cases but increases implementation complexity and requires strong content modeling expertise.

Contentful treats localization as a first-class concern. Its locale management, workflows, and permission controls are designed for enterprise-scale global operations, making it a strong choice for organizations managing content across many regions with consistent governance.

How to avoid common mistakes when choosing your CMS

By the time teams begin comparing CMS platforms, they usually have a clear goal: reduce friction, improve scalability, or better support new channels. What is often underestimated is how many real risks are organizational rather than technical.

Most CMS missteps come from reasonable assumptions that go unchallenged during evaluation. The following areas are where those assumptions tend to break down.

Don’t choose based on surface-level appeal. Choose based on requirements.

It is easy to gravitate toward platforms that appear frequently in case studies, conference talks, or peer recommendations. While those signals can be useful, they rarely reflect the constraints of a specific organization.

Problems arise when teams follow perceived industry standards without assessing their own capabilities. A CMS that works well for a company with strong in-house frontend expertise may introduce unnecessary complexity for a team where content is primarily managed by marketing or communications.

Similarly, selecting a technically elegant solution without accounting for how content teams actually work often leads to friction. Editors may struggle with abstract content models or lack confidence when publishing, even if the underlying architecture is sound.

To avoid this, both developers and content creators should be involved early in the evaluation. Their perspectives surface different risks, and alignment between them is often a better predictor of success than any individual feature.

Don’t underestimate the learning curve

Headless CMS platforms require teams to adopt a structured content approach, regardless of the product chosen. The differences lie in how much of that structure is predefined versus left to the organization to define.

Some platforms require specific skills to customize effectively, particularly when content models and editorial interfaces are defined in code. Without experience in content modeling, teams may struggle to maintain consistency as requirements evolve.

Highly flexible systems can also overwhelm teams if boundaries are not clearly defined. Editors may face too many choices, while developers take on long-term maintenance responsibilities they did not anticipate.

Running a proof of concept with the actual people who will use the system daily – not only senior developers or architects – helps expose these issues early. It also provides a realistic sense of onboarding effort and ongoing operational cost.

Additionally, many organizations find that outsourcing non-core development functions provides the necessary burst capacity and specialized expertise in areas like AI and Cloud security to ensure a smooth transition

Don’t ignore the total cost of ownership (TCO)

Licensing costs are only one part of a CMS investment. Over time, usage patterns, team size, and feature needs tend to change in ways that significantly affect costs.

Many organizations underestimate how quickly they move beyond entry-level plans. API usage, additional environments, roles, localization features, and governance tooling often become essential rather than optional.

Enterprise pricing structures may also require long-term budget planning, particularly for organizations operating across regions or business units. These costs should be understood before scaling content volume and delivery channels.

A practical approach is to model future costs explicitly. Include expected team growth, traffic increases, localization scope, and integration needs. This helps prevent a situation where the CMS becomes a budget constraint rather than an enabler.

In short, before committing to a platform, CTOs should ensure they have a detailed software estimation that accounts for both the initial setup and the long-term operational costs.

Don’t overlook migration complexity

Migration effort is often discussed late in the evaluation process, even though it has long-lasting implications. Content structure decisions made during onboarding tend to persist for years.

Once content is created, translated, and consumed by multiple applications, reversing those decisions becomes expensive. The cost is especially high when frontend logic becomes tightly coupled to specific CMS data models or APIs.

API dependencies can also introduce technical debt if the platform does not align with future architectural direction. Teams may spend increasing effort maintaining workarounds instead of evolving their systems.

Evaluating export capabilities and content portability upfront provides a clearer picture of long-term risk. A CMS that supports structured, accessible exports reduces dependency and preserves strategic flexibility.

Don’t treat CMS selection as a one-off decision.

A CMS is not a static piece of infrastructure. It becomes part of how teams collaborate, plan releases, and scale content operations.

Treating the selection as a one-time decision ignores the fact that content strategies evolve. New channels, automation requirements, and organizational changes place different demands on the platform over time.

Instead, it is worth assessing how a CMS vendor supports ongoing evolution. Product roadmaps, ecosystem maturity, and support models all influence how well the platform adapts to change.

Choosing a CMS with a view beyond the initial launch reduces the likelihood of costly re-platforming later and creates a more stable foundation for long-term growth.

Evaluation checklist and next steps

A structured evaluation process reduces the risk of choosing a CMS that looks good in demos but struggles in real-world use.

The goal is not to exhaustively test every feature, but to validate whether a platform supports your actual workflows, team dynamics, and plans.

The steps below provide a pragmatic framework that works well for most organizations evaluating Storyblok, Sanity, Contentful, or similar platforms.

1. Assemble a cross-functional evaluation team

CMS decisions affect multiple roles, even if they are often initiated by engineering or IT. Running the evaluation in a narrow group increases the likelihood of blind spots.

At a minimum, the evaluation team should include a development lead, a content or marketing representative, and a project or product manager. Each brings a different perspective on risk, usability, and long-term maintainability.

Developers focus on architecture, APIs, and extensibility. Content teams evaluate usability, confidence when publishing, and workflow clarity. Project managers often surface operational constraints, such as onboarding effort, governance, and release coordination.

Having these perspectives represented from the start prevents late-stage objections that can derail adoption after launch.

2. Define must-have and nice-to-have requirements

Before touching vendor demos, it is worth aligning internally on what actually matters. Without this step, evaluations tend to drift toward feature comparison rather than fit.

Must-have requirements should reflect constraints rather than preferences. These often include security standards, compliance needs, supported delivery channels, localization requirements, and integration capabilities. If a platform cannot meet these, it should be eliminated early.

Nice-to-have requirements help differentiate between viable options. These might include editorial experience, preview capabilities, collaboration features, or extensibility options. While valuable, they should not override core constraints.

Documenting these requirements creates a shared reference point and makes trade-offs explicit rather than implicit.

3. Evaluate vendors using your own use cases

Vendor demos are helpful, but they are designed to show platforms at their best. Relying solely on them can create a false sense of fit.

Whenever possible, evaluate demos against your own content types, workflows, and publishing scenarios. This includes edge cases such as multilingual content, approval workflows, or complex page compositions.

Using your own examples makes gaps visible early and helps teams assess how much customization would be required to reach a usable state.

This approach also makes comparisons more objective, as each platform is assessed against the same criteria rather than its strongest selling points.

4. Requirements gathering: document how the content actually flows

The first practical step in deeper evaluation is to document current content workflows and pain points. This analysis should assess how content is created, reviewed, published, updated, and eventually retired.

Many issues attributed to “bad tools” are actually the result of unclear processes. Mapping these workflows clarifies what the CMS needs to support and where it should enforce structure versus allow flexibility.

At the same time, map all delivery channels that currently consume content or are planned for the near future. Websites, mobile applications, internal tools, and emerging channels all place different demands on content modeling.

Finally, identify integration requirements early. E-commerce platforms, CRM systems, analytics tools, and personalization engines often influence CMS architecture more than expected.

5. Proof of concept: validate assumptions with real usage

A proof of concept is the most reliable way to expose friction. It should be small, time-boxed, and representative.

Building a limited section of your site or application on two or three shortlisted platforms is usually sufficient. The goal is not to replicate the entire system, but to test core assumptions around content modeling, development effort, and editorial workflows.

It is critical that actual content creators participate at this stage. Observing how long it takes them to publish content, how confident they feel, and where they hesitate provides insights that cannot be captured in technical reviews alone.

Evaluating time-to-publish and the overall editing experience is often a deciding factor, particularly in organizations where content velocity is a competitive advantage.

6. Vendor assessment: look beyond features

Once technical and editorial fit has been validated, vendor evaluation becomes the focus. This step is often compressed, but it has long-term consequences.

Support responsiveness and usage terms should be reviewed carefully. Understanding how issues are handled, what support channels exist, and how usage is measured helps avoid surprises after launch.

Reviewing the product roadmap provides insight into how the platform is evolving. Investments in AI, automation, and content intelligence may not be immediately critical, but they can influence future capabilities and cost structures.

Finally, customer references within your industry offer valuable context. They reveal how the platform behaves under similar constraints and whether the vendor understands your domain.

A structured evaluation does not eliminate risk, but it makes trade-offs explicit and defensible. It also builds internal alignment, which is often just as important as the technical outcome.

Why you shouldn’t rush the CMS selection process

CMS migrations are expensive, both technically and organizationally. Rushing the decision often leads to years of suboptimal workflows and unnecessary friction. That’s when a software partner with CMS migration expertise can help the most.

Storyblok, Sanity, and Contentful are three battle-tested CMS platforms that can be strong choices for different use cases, and we hope this overview clarifies their differences and similarities.

Ultimately, each business has its own needs, and it’s essential to understand how each platform can best address those unique challenges.
