Top Sanity CMS Development Companies (July 2026 Rankings)

Eight agencies that have shipped Sanity CMS in production -- RaftLabs is on this list. We wrote our own entry with the same directness we applied to everyone else.

Sanity is not a plug-and-play CMS. The schema is defined in code, the Studio is customized per project, and GROQ queries are written by developers who understand the content graph they are querying. Every agency on the web will tell you they "work with Sanity." The ones who have shipped non-trivial Sanity implementations -- multi-locale publishing, filtered references, custom input components, CDN-optimized image pipelines -- are a much smaller group.

The eight companies on this shortlist: RaftLabs, Basement Studio, Stormid, Formidable, Netguru, Appnovation, Clarity Digital, and Thinkmill. This list is based on publicly available case studies, Clutch reviews, and community reputation in the Sanity ecosystem. No company paid for placement.

How we evaluated this list

No company paid for placement on this list.

1. RaftLabs

RaftLabs offers Sanity CMS development for mid-market businesses that need more than a blog setup -- structured content architectures for multi-market publishing, product catalogs, knowledge bases, and content-driven SaaS applications. The team has shipped Sanity + Next.js stacks where the requirement was content that non-developers could manage without breaking page layouts or missing SEO metadata fields.

What sets the RaftLabs approach apart is that the content model and the frontend are designed together. A content type in Sanity that does not reflect how the frontend consumes it creates friction -- editors add fields that never render, developers add workarounds, and the schema becomes a maintenance problem over time. RaftLabs runs content modeling alongside UI design, not after it. Sanity Studio customizations -- custom input components, custom desk structure, GROQ-powered reference filtering -- are scoped to what editors actually need, not what the schema theoretically supports.

Notable work -- Built a multi-locale Sanity + Next.js content platform for an enterprise hospitality client managing 400+ property pages across 12 regional variants. Delivered a product content management system for a mid-market B2B SaaS company, integrating Sanity with their existing Shopify and HubSpot stack via webhooks and field-level publish validation.

Pricing signal -- $29--$49/hr. Fixed-price engagements with milestone payments. Most Sanity implementation projects (schema design + Studio setup + Next.js frontend) run $40,000--$120,000 depending on content model complexity and integration scope.

What to watch -- RaftLabs is strongest when the engagement covers both Sanity and the frontend framework. If you need Sanity integrated with a proprietary frontend or a non-standard stack, evaluate fit against your specific technology combination before engaging.

• Best for: Mid-market businesses needing Sanity + Next.js with custom content modeling and Studio customization

• Specialization: Structured content architecture, multi-locale publishing, GROQ optimization, Sanity Studio customization

• Pricing: $29--$49/hr, fixed-price projects

• Clutch: 4.9/5 (50+ verified reviews)

2. Basement Studio

Basement Studio is a creative development agency with a deep track record in Sanity CMS implementations for design-forward brands and creative agencies. They are recognized in the Sanity community for work that pushes the Studio UX -- custom desk structures, interactive Portable Text components, and preview setups that make the editorial experience match the design quality of the published site.

Their Sanity work tends toward the editorial end of the spectrum: magazine-style content structures, campaign microsites with complex content relationships, and brand platforms where the Studio needs to accommodate non-technical creative directors. The agency has contributed to the Sanity community through open-source tooling and published case studies that show real schema architecture decisions rather than tutorial-level examples.

Notable work -- Delivered a Sanity-backed brand platform for a global creative agency with a custom Studio structure that allowed account managers to manage multi-brand content without developer access. Built a content-driven campaign microsite with Sanity + Next.js where each campaign page pulled from shared content blocks across multiple markets.

Pricing signal -- Premium creative agency rates; typically $100+/hr. Project engagements scoped on request. Expect a higher floor than pure development shops due to the design-led positioning.

What to watch -- Basement Studio's creative-first model is excellent for brands where design quality and editorial UX are primary requirements. If your Sanity project is primarily a technical integration -- data pipelines, API consumption, performance-critical query optimization -- their positioning may be more than you need.

• Best for: Design-forward brands needing a Sanity implementation where the Studio UX matches the quality of the published site

• Specialization: Creative brand platforms, editorial Sanity Studio customization, Portable Text extensions

• Pricing: $100+/hr, project-based

• Clutch: Verify via direct reference

3. Stormid

Stormid is a UK-based agency specializing in Sanity CMS implementations for enterprise clients, with a focus on content operations that scale across multiple editors and business units. Their work covers complex permission structures in Sanity Studio, dataset-per-environment deployment strategies, and migrations from legacy CMS platforms (Sitecore, Episerver, and similar enterprise systems) to Sanity.

The agency publishes detailed technical writing about Sanity -- GROQ optimization patterns, schema versioning strategies, and multi-dataset architectures -- which gives a reliable signal of their depth beyond surface-level implementations. They have delivered Sanity projects in regulated industries where content workflows require approval states and audit logging.

Notable work -- Migrated a UK financial services firm from a legacy Episerver CMS to Sanity + Next.js, delivering a content model for regulatory documents, product pages, and news that accommodated complex permission requirements across editorial and compliance teams. Built a Sanity implementation for a media company managing content across six separate publication brands from a shared dataset.

Pricing signal -- Mid-range UK agency rates; typically $75--$100/hr. Project minimums apply; contact for estimates.

What to watch -- Stormid's strength is enterprise-scale Sanity work with complex workflows and migrations. Smaller projects with simpler requirements may find their project scoping process heavier than needed.

• Best for: UK and European enterprises needing Sanity with complex permission structures, approval workflows, or migrations from legacy CMS platforms

• Specialization: Enterprise Sanity implementations, legacy CMS migration, multi-brand content operations

• Pricing: $75--$100/hr

• Clutch: Verify via direct reference

4. Formidable

Formidable is a React and GraphQL specialist agency that has delivered multiple Sanity + Next.js implementations for mid-to-large tech companies. Their open-source contributions to the React ecosystem signal genuine technical depth rather than surface-level framework familiarity.

Their Sanity work tends toward technically complex implementations: custom GROQ queries for large content graphs, Sanity + GraphQL bridge setups for clients with existing GraphQL APIs, and performance-optimized Next.js frontends where content query efficiency matters. They bring rigorous engineering practices to Sanity projects -- type safety from GROQ responses through to component props, automated schema validation, and deployment pipelines that include Sanity content migration steps.

Notable work -- Built a Sanity + Next.js content platform for a Series B SaaS company replacing a homegrown CMS, delivering custom Studio tooling for a non-technical marketing team alongside GROQ-optimized queries for a high-traffic documentation site. Implemented a Sanity + GraphQL hybrid for a client with an existing GraphQL API layer who needed Sanity as the content source without replacing their API contract.

Pricing signal -- Senior US engineering rates; typically $150--$200/hr. Project-based engagements available for defined scope.

What to watch -- Formidable is excellent when technical rigor and engineering practices are as important as delivery speed. Pure design-focused projects or budget-constrained clients will find their rate card a mismatch.

• Best for: Tech companies that want Sanity implemented with software engineering rigor -- type-safe queries, automated testing, CI/CD-integrated schema migrations

• Specialization: React/Next.js, GROQ performance, Sanity + GraphQL integrations, TypeScript

• Pricing: $150--$200/hr

• Clutch: 4.8/5 (verify for recency)

5. Netguru

Netguru is a Polish digital product agency with 15+ years of delivery and a team of 700+ that has shipped Sanity CMS implementations for clients across Europe and North America. Their size gives them the capacity to staff Sanity projects alongside broader digital transformation engagements -- design system work, backend API development, and analytics implementation -- without subcontracting.

Their Sanity capability sits within a broader headless CMS practice that also covers Contentful and Strapi, which is useful if you are still evaluating platforms. The agency has published comparative analysis of Sanity vs. Contentful for enterprise use cases that shows genuine platform depth rather than sales copy.

Notable work -- Delivered a headless e-commerce platform for a European fashion brand using Sanity for content management and Shopify for commerce, with GROQ-powered product editorial pages that allowed merchandisers to control content context without developer intervention. Built a Sanity-backed design system documentation site for a fintech company where the content model extended to component documentation and live code examples.

Pricing signal -- $50--$99/hr. Project-based engagements and dedicated team models available. European timezone availability with US-hour overlap for client calls.

What to watch -- Netguru's broad capability means Sanity is one service among many rather than a primary specialization. Verify that your project lead has direct Sanity production experience rather than adjacent headless CMS work.

• Best for: European companies or North American clients comfortable with European timezone overlap who need Sanity alongside broader digital product work

• Specialization: Sanity + Shopify, headless e-commerce, design systems, fintech digital platforms

• Pricing: $50--$99/hr

• Clutch: 4.7/5 (500+ reviews)

6. Appnovation

Appnovation is a Vancouver-based enterprise agency with a content technology practice that includes Sanity implementations for large-scale publishing operations. Their work in this space focuses on enterprise content governance -- structured approval workflows, multi-language content management, and integrations between Sanity and enterprise marketing stacks (Salesforce, Marketo, Adobe Analytics).

The agency's Sanity projects tend to be large in scope: content platforms for organizations managing thousands of documents across multiple markets, where the Studio configuration needs to accommodate dozens of editors with different permission scopes. They bring content strategy into the engagement rather than treating schema design as a technical task.

Notable work -- Built a Sanity content operations platform for a North American media company managing 50,000+ articles across eight regional editions, with a custom workflow layer in Sanity Studio for editorial, legal, and compliance review states. Delivered a Sanity + Next.js marketing site for a global professional services firm with 12-language support and region-specific content overrides.

Pricing signal -- Enterprise rates; typically $100--$150/hr. Minimum engagements apply. Suited to organizations with defined budget and procurement processes.

What to watch -- Appnovation is designed for large-scale enterprise engagements. Smaller companies or those with fast-moving requirements may find their process overhead and minimum engagement size a poor fit.

• Best for: Enterprise organizations managing large content volumes across multiple markets with complex editorial workflows

• Specialization: Content governance, multi-language Sanity publishing, enterprise marketing stack integrations

• Pricing: $100--$150/hr, enterprise engagements

• Clutch: 4.6/5 (verify for recency)

7. Clarity Digital

Clarity Digital is a UK-based digital agency with a specific focus on headless CMS implementations for media and publishing clients. Their Sanity work covers structured editorial content -- article hierarchies, tagging taxonomies, multimedia content models, and automated content syndication pipelines. They have shipped Sanity implementations where the content model extended to third-party data ingestion and structured data for Google News.

The agency has built custom Sanity Studio plugins for media clients that handle content scheduling, automated image captioning via AI pipelines, and structured data injection for AMP and news feeds. Their focus on media-specific requirements makes them a specialist choice for publishers rather than a generalist development agency.

Notable work -- Built a Sanity-backed digital publishing platform for a UK regional media group, replacing a 15-year-old proprietary CMS with a content model that accommodated print, web, and social publishing workflows from a single content source. Implemented a structured data layer in Sanity for a financial news service, automating schema.org Article markup generation from content fields.

Pricing signal -- UK agency rates; $75--$100/hr. Media and publishing clients preferred.

What to watch -- Clarity Digital's specialization is a strength if you are in media or publishing, and a potential mismatch if your Sanity project is e-commerce, SaaS documentation, or brand marketing.

• Best for: Media companies and publishers needing Sanity with editorial workflow customization, content scheduling, and structured data automation

• Specialization: Publishing platforms, editorial Sanity Studio, structured data, content syndication

• Pricing: $75--$100/hr

• Clutch: Verify via direct reference

8. Thinkmill

Thinkmill is an Australian product engineering agency and the creator of Keystonejs -- an open-source headless CMS that sits alongside Sanity in the structured content space. Their Sanity capability is built on genuine CMS architecture depth: they approach schema design with an understanding of long-term maintainability that frontend-only agencies miss.

For Sanity projects, Thinkmill brings strong TypeScript and backend engineering practices. Their open-source work on content management systems means they can reason about the architecture, not just the implementation -- which matters when requirements change after launch.

Notable work -- Delivered a Sanity content platform for a Sydney-based media startup building a content-driven SaaS product, where the Sanity schema served as the structured data layer for both the editorial frontend and the customer-facing product. Contributed open-source tooling that integrates Keystone and Sanity content models for teams migrating between platforms.

Pricing signal -- Australian agency rates; $75--$100/hr AUD (approx. $50--$65/hr USD). Project-based engagements with defined scope.

What to watch -- Thinkmill's primary CMS product is Keystone, not Sanity. Verify that the team assigned to your project has shipped Sanity in production rather than adjacent CMS work.

• Best for: Australian companies or global teams who want a Sanity partner with genuine CMS architecture depth

• Specialization: Content modeling, TypeScript, headless CMS architecture, open-source tooling

• Pricing: $75--$100/hr AUD

Side-by-side comparison

The question that separates Sanity specialists from CMS generalists

The question to ask every agency is not "Do you work with Sanity?" It is: "Can you show me a GROQ query you wrote for a production project that was not a tutorial?"

Any agency that has used Sanity beyond the basics has written GROQ. Querying a single content type with a _type == "post" filter is not evidence of depth. Writing a query that traverses references, handles conditional field selection, and returns a flattened array for frontend consumption tells you something real about their experience.

The same logic applies to Sanity Studio configuration. Any agency can use the default desk structure. The ones who have built custom input components -- an image field with aspect-ratio enforcement, a reference selector filtered by a related field's value, a portable text component that validates internal links against the content model -- have worked on projects with editorial requirements that pushed past the defaults.

Getting the schema wrong is more expensive than getting the vendor wrong. A content model that does not reflect how content is actually created and consumed creates friction for editors and performance problems for the frontend. That friction compounds: content operations slow down, developers add workarounds, and the schema accrues technical debt that no refactor fully resolves. Choose a partner who treats content modeling as the most important phase of the engagement, not a pre-implementation checklist item.

What the research shows

The headless CMS market is growing consistently. According to MarketsandMarkets, the headless CMS market is projected to reach $3.7 billion by 2028, growing at a CAGR of 22.1% -- driven by the need for content delivered across web, mobile, voice, and digital experience platforms simultaneously. Sanity's API-first architecture and GROQ query language make it well-positioned for organizations managing content across multiple frontends.

Sanity's co-founder Even Westvang has described Sanity's approach as treating content as data -- the idea that structured content, when modeled correctly, can be composed and queried as flexibly as any database. The practical implication for buyers: the content model is the long-term investment, not the Studio configuration or the frontend. Agencies that understand this build schemas that remain useful as requirements evolve.

Five questions to ask before signing

1. What non-trivial GROQ queries have you written in production?

Ask for examples, not descriptions. A specific GROQ query -- even abbreviated -- tells you more about experience than a paragraph about "deep Sanity expertise."

2. How do you handle schema migrations after launch?

Content schemas change after launch -- new fields are added, existing types are split or merged. Ask how they version schema changes, handle content that exists in the old format, and coordinate schema deployments with Studio updates.

3. Have you built custom input components or custom desk structure?

Standard Sanity Studio configuration is table stakes. Custom input components (fields with validation, custom UI, conditional logic) and custom desk structure (organizing the Studio navigation for non-developers) are the real signal of experience.

4. How do you handle multi-locale publishing, if we need it?

Sanity's locale support requires deliberate schema design decisions -- whether to use field-level translations or document-level translations, how to handle shared content across locales, and how the Studio accommodates translators who should not see the schema configuration layer.

5. What is your CDN and ISR strategy for the frontend?

Sanity delivers images via CDN and supports webhooks for cache invalidation. On Next.js, on-demand ISR triggered by Sanity content events is the standard approach. Ask how they implement this and what the latency looks like between a content publish and a live page update.
