Your CMS Slows Down Every Page Your Marketers Ship
Content trapped inside page templates
When copy, images, and metadata live inside one giant page record, nothing can be reused. Your team rewrites the same product description for the resource hub, the solution page, and the localized site. Sanity solves this at the schema level, but only if the schema is designed correctly, and schema design is where most builds go wrong.
Developers gate every publish
Marketers file a ticket to add a case study, change a hero, or launch a campaign landing page. Weeks pass. A Sanity Studio built without editor workflows in mind recreates that bottleneck in a newer tool — a pattern we see repeatedly in inherited builds.
A migration nobody planned for
Moving a decade of WordPress or Drupal content to Sanity means reconciling messy taxonomies, redirects, gated assets, and CRM form mappings. Teams that treat migration as a final-week task lose rankings and lead capture. It needs a scripted plan and a content audit up front.
From Content Model Workshop To Monitored Launch
Discovery and content modeling
We run a content model workshop with your marketing and product stakeholders, then deliver a documented schema map: every content type, field, reference, and reusable block. You also get a migration inventory of existing URLs, gated assets, and redirects.
Sprint-based Studio and frontend build
We build Sanity Studio with custom input components, validation rules, and role-based publishing workflows, paired with a React or Next.js frontend. Each sprint ends with a working preview environment your editors can test, not a status slide.
Integration and testing
We wire GROQ queries, webhooks, ISR or on-demand revalidation, search, localization, and CRM handoffs to HubSpot or Salesforce. QA covers accessibility, Core Web Vitals, editor acceptance testing, and a redirect map validated against your current URL set.
Launch and enablement
We ship with a scripted content migration, deployment pipeline, and monitoring in place. Your team receives recorded Studio training, a schema and component documentation set, and a prioritized post-launch backlog for the next two release cycles.
Get A Sanity Build Your Content Team Actually Wants To Use
“I am currently working on a site migration with O8. They are very responsive and do great work. I really enjoy working with them. I even look forward to meetings with the team, because I can discuss issues, work out solutions, and learn new things as well.”
Christina Goodland
Website Manager • OIT, UMN
“The O8 team has exceeded our expectations and been an incredible resource as we navigated the challenges of deploying complex projects. They've proved to be extremely responsive, creative, and responsible partners in the design, development, and deployment processes and I recommend them highly.”
Chris Scruton
Academic Technology Systems Analyst • University of Minnesota OIT
“We had a great experience working with O8 — they are professional, thorough and think broadly about any given project.”
What You Get From O8 That Most Sanity Shops Skip
Schema design before syntax
We start with how your team writes, reviews, and reuses content, then design the Sanity schema around that. The result is fewer one-off page types and less rework six months after launch.
Editor experience as a deliverable
Custom Studio inputs, previews, validation, and approval steps are scoped, built, and tested with the people who publish. Editor acceptance testing is part of QA, not an afterthought.
Migration handled as engineering
We script migrations from WordPress, Drupal, and other legacy platforms, with content audits, taxonomy mapping, and a validated redirect plan so search visibility and form capture survive the cutover.
Full-stack depth in house
Our team works across Node.js, React, PHP, Laravel, Symfony, and multiple headless CMS platforms. If your Sanity build needs a custom API, a legacy integration, or a phased hybrid, we can build it.
Senior people on your project
You work directly with strategists and engineers who make decisions, not a rotating cast of account coordinators — the kind of continuity that keeps 84% of our clients working with us past the first engagement.

Sanity treats structured content as queryable data. Instead of fetching a fixed page object, you query exactly the fields and references you need with GROQ, which makes content reuse across templates, campaigns, and locales much simpler. Sanity Studio is also a React application you extend with your own components, so the editing interface can match your team's workflow rather than the other way around.
We do not quote a package price before we understand your content model, integration surface, and migration volume. Scope and pricing are determined after an assessment of how your team operates: how many content types you need, which systems must connect, how much legacy content moves, and who approves what. You get a fixed scope with named deliverables before any development starts.
Yes, particularly when the same product, solution, and proof content needs to appear across many page types, segments, or languages. Structured content lets you update a claim once and have it propagate everywhere it appears. Sanity also handles gated assets, referenced resource libraries, and CRM form routing without template duplication.
Yes, and that pairing is the most common way we build. Sanity provides official client libraries and image tooling for React, and Next.js handles routing, rendering strategy, and revalidation. We use webhooks and on-demand revalidation so an editor's publish action updates the live site in seconds without a full rebuild.
Timeline depends on content model complexity, migration volume, and how many integrations are in scope. A focused build with a defined schema and a clean content inventory moves considerably faster than one with a decade of unstructured legacy pages. We give you a sprint-level schedule after discovery, and each sprint ends with a preview environment you can review.
What Is a Sanity CMS Development Agency?
A Sanity CMS development agency designs, builds, and maintains websites and applications on Sanity, a headless content platform where content is stored as structured, queryable data rather than as fixed page templates. The work covers four things: modeling content types and their relationships, building and extending Sanity Studio so editors can publish without developer help, building the frontend that consumes Sanity content through GROQ queries or GraphQL, and connecting the platform to the rest of your stack through webhooks and APIs.
The distinction matters because Sanity gives you very little out of the box by design. There is no theme marketplace and no default page builder. Everything an editor sees is something someone decided to build. That freedom produces excellent results with a strong content model and a frustrating experience without one, which is why agency selection has more impact on Sanity than on template-driven platforms.
When Does a Company Need Sanity CMS Development?
A company needs Sanity CMS development when its existing CMS can no longer support the content complexity, publishing speed, or integration requirements the business has grown into. The signals are consistent across the organizations we talk to:
- Marketers wait on developers to publish routine pages, campaigns, or case studies.
- The same product claim or spec lives in six places and is wrong in three of them.
- Content needs to appear on a website, an app, an email system, and a sales portal from one source.
- Localization means maintaining parallel sites instead of translated fields.
- Page speed suffers under plugin weight, and Core Web Vitals scores drag down organic performance.
- Approval workflows involve legal, compliance, or clinical review that the current CMS cannot model.
If those problems are mostly about templates and theme flexibility rather than content structure, a headless move may be premature. We say so. Sometimes the right answer is a focused effort with our Custom WordPress Development Agency team or a scoped rebuild through our Website Redesign Agency practice instead of a platform change.
Sanity Compared To A Traditional Template CMS
| Dimension | Traditional template CMS | Sanity |
|---|---|---|
| Content storage | Page-centric records tied to templates | Structured documents with typed fields and references |
| Content retrieval | Theme loop or plugin queries | GROQ or GraphQL queries returning only requested fields |
| Editing interface | Fixed admin UI, extended via plugins | Sanity Studio, a React app you extend with custom components |
| Reuse across channels | Duplicated content or bolt-on APIs | One content source consumed by web, app, and internal tools |
| Frontend choice | Coupled to the platform's rendering layer | Any framework, most commonly React or Next.js |
| Main risk | Plugin sprawl and performance decay | A weak content model that no plugin can rescue |
What Does a Good Sanity CMS Development Engagement Look Like?
A good Sanity CMS development engagement starts with a content model workshop, not code. The agency maps every content type your organization publishes, identifies which fields are shared, decides what should be a reference versus an embedded object, and writes that down before a single schema file exists. That document becomes the contract between marketing, product, and engineering.
From there, the build proceeds in sprints with a reviewable preview environment at the end of each one. Editors test the Studio while it is still cheap to change. Migration runs as scripted engineering work with a content audit and a validated redirect map, not as a weekend copy-paste exercise. Launch includes recorded training, schema documentation, and a prioritized backlog so the platform keeps improving after the invoice clears.
What separates a strong engagement from an average one is the definition of success. Delivering on the launch date is table stakes. We evaluate a Sanity build on what happens afterward: how quickly your team ships a new page without a ticket, how the site performs on Core Web Vitals, and whether the content structure supports the campaigns you want to run next quarter. That is the same standard we hold across our Web Design & Development Services work.
What O8 Delivers On A Sanity Build
Named deliverables, not vague phases. Every Sanity engagement includes a documented content model and schema map, a migration inventory with redirect plan, a custom Sanity Studio with validation and role-based publishing workflows, a React or Next.js frontend with on-demand revalidation, integration wiring to your CRM and marketing automation, an accessibility and Core Web Vitals QA report, recorded editor training, component documentation, and a two-cycle post-launch backlog.
Our team works across the full modern stack, including Node.js, React, PHP, Laravel, Symfony, and multiple headless CMS platforms, so a Sanity project can include the custom API work or legacy system integration it actually requires. If you also want AI-driven features on the frontend, such as search, recommendations, or content automation, our AI Web Development Agency team scopes that work alongside the CMS build rather than as a separate project.
How Much Does Sanity CMS Development Cost?
We do not publish a price range for Sanity CMS development, and we would treat any agency that does with some skepticism. Cost is driven by variables that only surface in an assessment: the number of content types and reusable blocks, how much Studio customization your approval workflow requires, the volume and condition of legacy content moving over, how many systems need to exchange data, and whether localization or gated content is in scope.
Our approach is to run an operating-model assessment first. We look at how your team publishes today, who approves what, where content duplicates, and which integrations are load-bearing. You get a fixed scope with named deliverables, a sprint schedule, and clear assumptions before development begins. If the assessment shows Sanity is the wrong tool for your situation, we tell you that too.
Migrating From WordPress Or Drupal To Sanity
Most Sanity projects we take on are migrations, not greenfield builds. That means the risky work is not the new site. It is the 800 existing URLs, the taxonomy nobody has audited since 2019, the gated PDFs behind form fills, and the tracking parameters sales relies on. We script content transformation, map old fields to new schema types, validate redirects against a crawl of the live site, and keep form capture continuous through cutover. Companies with complex buying committees and long consideration cycles usually pair this with the account-level content strategy our B2B Web Design Agency team brings to the table.
How Our Delivery System Supports Sanity Delivery
Behind every Sanity engagement, we run O8 Intelligence, our internal delivery infrastructure. For CMS builds, it maintains a connected record of content model decisions, migration mappings, redirect validation, and post-launch performance signals in one auditable trail. That means when a question comes up six months after launch about why a field was structured a certain way or which URL mapped where, we have the answer documented rather than reconstructed. It is delivery tooling we operate, not a product you have to learn.
Start With The Content Model
The fastest way to know whether Sanity fits is a conversation about how your team publishes today and what breaks. Bring your current pain points, your integration list, and your next two quarters of campaign plans. We will tell you what a realistic scope looks like.
