Four platforms. Four completely different philosophies about how content should work. And if you pick the wrong one, you'll spend the next two years fighting your CMS instead of growing your business.
Sanity treats content like data. Contentful treats it like enterprise software. Storyblok treats it like a design system. Strapi treats it like code. None of them are wrong — but one of them is probably right for you, and the others will make your life harder in ways you won't notice until six months in.
We've worked with all four on real projects. This isn't a feature checklist copied from marketing pages — it's an honest comparison based on what actually matters when you're building something that needs to last.
The Quick Version
If you're short on time, here's the summary. If you want the reasoning, keep reading.
| Sanity | Contentful | Storyblok | Strapi | |
|---|---|---|---|---|
| Best for | Teams that need flexibility and real-time collaboration | Enterprises needing governance and compliance | Marketing teams wanting visual page building | Dev teams wanting full control and self-hosting |
| Pricing model | Per user ($15/user/mo) | Tiered (starts at $300/mo) | Per user ($99/mo base + $15/user) | Free (open-source) or cloud from $15/mo |
| Free tier | 20 users, 10K docs, 200K API calls | 5 users, 2 locales, 1M API calls | 1 user, 100K API calls | Unlimited (self-hosted) |
| Content editor experience | Customizable (depends on setup) | Structured forms | Visual editor (WYSIWYG) | Basic, improving |
| Developer experience | Excellent (GROQ, custom Studio) | Good (mature SDKs) | Good (component-based) | Excellent (full code control) |
| G2 rating | 4.7/5 | 4.2/5 | 4.4/5 | 4.5/5 |
| Main limitation | Requires dev investment to set up | Rigid, expensive at scale | Weaker for non-page content | Self-hosting overhead |
How Each Platform Actually Works
Sanity: Content as Data
Sanity's core idea is that content is structured data, not pages. You define your content models in code (TypeScript/JavaScript), and everything lives in what they call the "Content Lake" — a real-time database you can query with GROQ, their custom query language.
The Studio — where editors manage content — is a React application you fully customize. This is both Sanity's superpower and its main demand: a well-configured Studio feels intuitive and powerful, tailored to exactly how your team works. A poorly configured one feels confusing.
What stands out:
- Real-time collaboration that works like Google Docs — multiple people editing the same document simultaneously
- Content Agent (launched Feb 2026) reads your content schemas and enables conversational querying and bulk updates. Morning Brew and Complex have used it for content audits; Home Instead updated Facebook links across 1,100 locations in a single conversation
- GROQ enables surgical queries that other platforms can't match — "fetch documents where field X changed AND contains 'sale' AND price less than $10"
- Generous free tier: 20 users, which is more than most competitors offer on paid plans
The trade-off: You need developers to get value from Sanity. The flexibility is real, but so is the setup investment. Teams without engineering resources should look elsewhere.
Contentful: Enterprise-Grade Content Infrastructure
Contentful is the platform your CTO has probably already heard of. It's been around longest, has the most enterprise deployments, and positions itself as serious infrastructure for serious organizations.
The content editing experience is form-based — structured fields in well-defined content types. No visual preview by default. You fill in the forms, the content goes to the API, your frontend renders it. This approach prioritizes consistency and governance over editorial flexibility.
What stands out:
- Battle-tested infrastructure — 90%+ cache hit rates, 0.003% error rate during Black Friday, handles 35,000 requests per second
- Mature SDK ecosystem across JavaScript, Python, Ruby, iOS, Android
- Formal approval workflows and role-based permissions built for regulated industries
- AI Actions framework for translations, localization, SEO optimization, and personalization (launched 2025)
The trade-off: Contentful is expensive and rigid. The Basic plan starts at $300/month with limits on content types (48 max), locales (3), and users (20). Hard content-type limits mean you'll hit architectural walls as your project grows — one documented case involved an organization unable to add a second report type after reaching 149 of 150 content types. And adding locales multiplies costs quickly for global operations.
Storyblok: Visual Editing for Marketing Teams
Storyblok's defining feature is its Visual Editor — a genuine WYSIWYG experience where editors click on elements in a live preview to edit them. Content changes appear in real-time. If your marketing team has ever complained that "headless CMS" means "we can't see what we're doing," Storyblok is the answer.
The content model is component-based: developers define reusable components with specific properties, and editors assemble them into pages like building blocks. This aligns naturally with how modern frontend frameworks (React, Vue, Astro) work.
What stands out:
- Visual Editor that genuinely works — editors see exactly what they're building, no guessing
- Component-based architecture that mirrors frontend development patterns
- Framework-specific SDKs for Next.js, Nuxt, Astro, SvelteKit that handle visual editor integration automatically
- Release Merging (new in 2026) auto-detects when approved content changes post-approval and flags it for review
The trade-off: Storyblok's strength with page-driven content becomes a weakness for omnichannel delivery. If your content needs to power a mobile app, voice assistant, or IoT device — not just web pages — the visual, component-based model provides less value than pure structured data approaches. Pricing also escalates: the Growth tier starts at $99/month for 5 users, with additional users at $15/month each, and locales costing $20/month each.
Strapi: Open-Source Freedom
Strapi is the open-source option. The Community Edition is free — forever — with unlimited content types, unlimited API calls, and unlimited entries. You host it yourself, you control everything, and you never answer to a SaaS vendor.
The platform auto-generates REST and GraphQL APIs from your content models, eliminating boilerplate while giving developers full control to customize controllers, middleware, and business logic.
What stands out:
- Genuinely free with no artificial limits on content or API usage
- Full code control — customize anything, deploy anywhere
- AI Content-Type Builder generates content structures from natural language or Figma designs (launched 2025)
- AI Translations automatically translate content into configured locales on save
- No vendor lock-in — your data, your infrastructure, your rules
The trade-off: Self-hosting isn't free in practice. Research shows self-hosted deployments require 45–48% more operational time than managed platforms. Security patching alone can consume 300–1,300 hours annually per team member. For a team of five, that operational overhead translates to $78,000–$325,000 per year in hidden costs. Strapi Cloud (managed hosting from $15/month) mitigates this, but then you're paying SaaS prices anyway — just with more configuration responsibility.
Head-to-Head: Sanity vs Contentful
This is the comparison people agonize over most. Both are cloud-hosted, API-first, enterprise-capable. But they serve fundamentally different organizational styles.
| Factor | Sanity | Contentful |
|---|---|---|
| Pricing entry | $15/user/month (Growth) | $300/month flat (Basic) |
| Content modeling | Fully flexible, code-defined | Structured but constrained (48–150 type limits) |
| Query language | GROQ (purpose-built, powerful) | REST + GraphQL (standard) |
| Real-time collaboration | Yes (Google Docs-style) | No (form-based, sequential) |
| Editorial experience | Custom-built Studio | Structured forms |
| Governance | Flexible (build what you need) | Built-in (formal workflows) |
| Free tier | 20 users | 5 users |
| Ideal org | Fast-moving teams, custom workflows | Regulated enterprises, complex legacy stacks |
Choose Sanity if your team values flexibility, real-time collaboration, and building content workflows tailored to how you actually work. The per-user pricing ($15/user) makes it significantly cheaper than Contentful for teams under 20 people.
Choose Contentful if you're in a regulated industry where formal approval chains, compliance audits, and proven enterprise infrastructure matter more than customization speed. The higher cost buys you battle-tested reliability at massive scale.
Head-to-Head: Strapi vs Sanity
This comparison comes down to philosophy: do you want to own your infrastructure or let someone else manage it?
| Factor | Strapi | Sanity |
|---|---|---|
| Cost model | Free (self-hosted) or from $15/mo (cloud) | From $15/user/month |
| Hosting | Self-hosted or Strapi Cloud | Managed (cloud only) |
| Data ownership | Full (your servers) | Sanity-hosted Content Lake |
| API generation | Auto-generated REST + GraphQL | REST + GraphQL + GROQ |
| Customization | Unlimited (code-level) | Unlimited (Studio-level) |
| Operational burden | High (self-hosted) / Medium (cloud) | Low (managed) |
| Editor experience | Basic, improving with Live Preview | Excellent when properly configured |
| Ideal org | Teams with DevOps, data sovereignty needs | Teams wanting managed infrastructure with flexibility |
Choose Strapi if data sovereignty is non-negotiable (healthcare, government, finance), your team has strong DevOps capabilities, or you want zero vendor dependency. The free Community Edition is genuinely unlimited — if you can manage the infrastructure.
Choose Sanity if you want similar developer flexibility without the operational overhead. Sanity's managed infrastructure means your team builds features instead of managing servers. The Content Lake's real-time capabilities (live content updates, simultaneous editing) are architecturally impossible with self-hosted Strapi.
Head-to-Head: Storyblok vs Sanity
The visual editor versus the customizable studio. Marketing team independence versus developer-crafted precision.
| Factor | Storyblok | Sanity |
|---|---|---|
| Editor experience | Visual (WYSIWYG, drag-and-drop) | Customizable (form-based, tailored) |
| Content model | Component-based (page-focused) | Structured data (channel-agnostic) |
| Non-technical user friendliness | Excellent out of the box | Depends on developer setup |
| Omnichannel suitability | Weaker (page-oriented) | Strong (content as data) |
| Pricing (5 users) | $99/month base | $75/month (5 × $15) |
| Localization cost | $20/locale/month | Included |
| Setup speed | Faster (visual tools) | Slower (requires Studio configuration) |
| Ideal org | Marketing-led, page-heavy websites | Content-as-data, multi-channel delivery |
Choose Storyblok if your marketing team needs to build and edit pages independently, your content is primarily web-page-driven, and you want the fastest path to editors working autonomously. The visual editor is genuinely best-in-class.
Choose Sanity if your content powers more than just web pages (mobile apps, voice, IoT), you need sophisticated content modeling that goes beyond page components, or you want to build a perfectly tailored editorial experience through the customizable Studio.
The Real Cost Comparison
Monthly subscription prices are misleading. What matters is what you'll actually spend over two years, including development, hosting, and ongoing maintenance.
| Cost Factor | Sanity | Contentful | Storyblok | Strapi (self-hosted) | Strapi Cloud |
|---|---|---|---|---|---|
| Platform (10 users, annual) | ~$1,800/yr | ~$3,600/yr+ | ~$1,900/yr | $0 | ~$900/yr |
| Additional locales (5) | Included | Custom pricing | ~$1,200/yr | Included | Included |
| Initial dev setup | $10K–$30K | $10K–$40K | $8K–$25K | $15K–$50K | $10K–$35K |
| Annual maintenance | $5K–$15K | $5K–$15K | $5K–$15K | $20K–$80K | $8K–$20K |
| 2-year total estimate | $30K–$65K | $35K–$85K | $25K–$60K | $55K–$210K | $30K–$75K |
The surprise is Strapi self-hosted. "Free" software often costs the most when you factor in the infrastructure management, security patching, and DevOps time. It's the right choice for organizations with existing DevOps infrastructure — but it's not the budget option it appears to be.
Which One Should You Choose?
After all the comparisons, the decision usually comes down to answering three questions:
Who manages your content day-to-day?
- Mostly marketing/editors → Storyblok (visual editor wins)
- Mixed technical and editorial team → Sanity (customizable to fit both)
- Content is an engineering concern → Strapi (maximum dev control)
- Large enterprise with formal processes → Contentful (governance built in)
Where does your content need to go?
- Website only → Any platform works; Storyblok is fastest to set up
- Website + mobile app → Sanity or Strapi (structured data, API-first)
- Website + app + IoT + voice → Sanity (Content Lake handles omnichannel natively)
What are your operational capabilities?
- No DevOps team → Sanity, Contentful, or Storyblok (managed platforms)
- Strong DevOps, data sovereignty needs → Strapi self-hosted
- DevOps but prefer managed → Strapi Cloud or Sanity
Whatever you choose, the migration process matters as much as the platform. A great CMS implemented poorly will underperform a mediocre CMS implemented well. Plan the transition carefully, preserve your SEO, and give your team time to learn the new system before judging the results.
