Sanity CMS Development Agency

Build a content platform that will not box you in.

Flight is a Sanity CMS development agency and official Sanity Agency Partner. We design, build, migrate and improve scalable digital platforms using Sanity, structured content and modern frontend technology.


Strategy, UX, content modelling, development, SEO and performance come together to create a fast, flexible platform that works for your customers, gives your content team more control and can evolve without another full rebuild.

Modern content management built for what's next.

Sanity is a headless CMS and structured content platform. It keeps your content separate from the website or app displaying it, so you can manage information once and use it across multiple digital experiences.


Sanity Studio gives editors a workspace shaped around the way they create and publish. The Content Lake stores content as structured data, while APIs deliver the right content to the right channel.


That makes Sanity a strong choice for organisations managing complex content, multiple markets, ecommerce experiences or digital products that need to keep moving.


Want a closer look at the platform? Read five reasons we love Sanity CMS, from flexible content structures and collaborative editing to its role in a modern digital ecosystem.


What Does a Sanity CMS Development Agency Do?

A Sanity CMS development agency plans, designs, builds and supports digital platforms powered by Sanity. This can include solution architecture, content modelling, Sanity Studio configuration, frontend development, integrations, CMS migration, technical SEO, testing, launch support and ongoing optimisation.


The most useful agency work goes beyond configuring the CMS. It connects the content model, editorial workflow, customer experience, frontend architecture, integrations, search visibility and long term platform goals.


Flight helps organisations make those decisions together, so the platform is useful on launch and remains practical to manage as requirements change.


Sanity in Context

Sanity’s platform overview reports more than 1 million users and 6,000+ teams using the platform. Sanity also lists 99.95% uptime and 24/7 support as part of its enterprise offering. These figures describe Sanity’s published platform claims, not a guaranteed result for every implementation.


Sanity’s customer stories show the scale that structured content can support in the right environment. For example, Sanity reports that PUMA manages 50,000 reusable content pieces, ingests 12,000 product categories hourly and creates 4,000 hero banners through its platform.

That is a customer specific example, but it illustrates why a structured content model can be valuable for large, multi market organisations.

Sanity CMS Developers With Real World Experience

The goal is not simply to launch Sanity. It is to build a digital foundation your organisation can manage, measure and improve over time.

Sanity CMS Development Services Shaped Around Your Platform

A Sanity CMS development agency should do more than configure a CMS. The real job is connecting your content, workflows, frontend, integrations, search visibility and long term platform goals.
Flight can help you launch a new Sanity build, move from an existing CMS or get more from a platform that is already live.



Sanity Strategy and Solution Architecture


We start with what the platform needs to achieve, not a predetermined technology stack. We look at your audiences, content operations, existing technology, business goals and future plans, then shape a practical Sanity architecture around them.


Content Modelling and Sanity Studio Development


We structure content around meaning and reuse, rather than locking it into individual page layouts.
Our developers configure schemas, validation, permissions, previews and editorial tools so your team can work confidently without fighting the CMS.



Headless Website and Application Development


We connect Sanity to modern frontend frameworks and build responsive experiences around real customer needs.


That could be a corporate website, ecommerce storefront, publishing platform, campaign ecosystem or custom application.


Sanity CMS Migrations


We plan and deliver migrations from traditional, legacy and headless content management systems.


We plan and deliver migrations from traditional, legacy and headless content management systems. Content, metadata, media, relationships and URLs are mapped carefully, so the new platform is a genuine step forward without leaving valuable information or organic visibility behind.


Platform integrations


We connect Sanity with the systems your organisation already relies on, including Shopify, analytics platforms, search tools, customer platforms and custom APIs.


Every integration needs a clear purpose for your team or your customers.


Ongoing support and optimisation


Launch is the starting line. We can keep improving your Sanity platform with new functionality, smarter content models, performance work, technical SEO, experimentation and ongoing development support.

A headless CMS designed for modern website development.

Traditional CMS platforms often bundle content, presentation and functionality into one system. That can work well for a straightforward website, but things can become rigid when you need a redesign, a new integration or content across more than one channel.


Sanity takes a headless approach. Your content is managed independently from the frontend, giving you more freedom to change the customer experience, introduce new channels and adopt new technology without replacing the content foundation each time.


It also gives developers the freedom to choose the frontend tools that best suit the job. Flight commonly works with technologies such as Next.js and React to build fast, responsive interfaces, with Sanity managing the content underneath.


This same approach sits behind JAMstack website development, where APIs, modern frontend frameworks and decoupled services come together to create flexible digital experiences.


Structured content that works harder

Structured content turns a collection of separate pages into a connected content system. Information is created in reusable fields and content types, then delivered wherever it needs to go.

For content and marketing teams, that means fewer duplicated updates, better consistency and faster publishing across websites, regions, campaigns, apps and ecommerce experiences. For developers, it creates a cleaner foundation for new features and channels.


We design Sanity content models around how your organisation actually works. That can include reusable campaign modules, product information, author profiles, resources, locations, approval workflows, localisation and relationships between content types.


Sanity can also support visual editing, live previews and tailored workflows, helping editors see how content will appear before it goes live.

Our introduction to Sanity Create looks at how Sanity is developing its AI-assisted content experience.



Composable architecture, one joined up experience

A composable platform brings together specialised technologies instead of asking one system to do everything. Sanity can manage the content layer while ecommerce, search, analytics, personalisation and customer platforms each do what they do best.


The upside is choice. You can add, replace or improve individual capabilities as your needs change. The tricky part is making sure those systems behave like one platform rather than a collection of disconnected tools.


That is where Flight comes in. We design the customer experience, data flow and integration logic as one connected system.


Sanity can be integrated with Shopify, Next.js, React, search technologies, analytics tools, customer platforms and custom services, while the experience stays coherent for customers and manageable for your team.


Move to Sanity without losing what already works

A Sanity migration is not a copy and paste exercise. It is a chance to improve the content model, clear out unnecessary complexity and protect the signals your customers and search engines already rely on.


We begin by auditing the current platform, content, URLs, integrations and publishing workflows. From there, we map the new content structure, decide what should be migrated, consolidated or retired, and plan how each connected system will work after launch.


During the build, we test content relationships, templates, permissions, forms, integrations and editorial workflows. Search requirements are included throughout, with URL mapping, redirects, metadata, headings, canonicals, structured data, XML sitemaps and analytics considered before release.


The goal is simple: reduce launch risk and give your team a cleaner foundation for growth.

SEO friendly Sanity development starts with the build

Sanity gives you the flexibility to build a fast, search friendly website. But the CMS alone cannot guarantee strong SEO. The outcome depends on the content model, frontend, rendering setup, metadata and technical foundations around it.


Flight brings SEO into the build from day one. We plan editable metadata fields, logical heading structures, indexation controls, canonical tags, structured data, internal linking options and redirect requirements as part of the platform, not as a rushed launch checklist.


We also account for page speed, image delivery, crawlability, JavaScript rendering and measurement. That helps search engines and AI systems understand the website, while giving your team the controls to keep optimising after launch.


Is Sanity the right CMS for your organisation?

Sanity is particularly useful when your content needs to do more than fill one fixed website, or when a standard CMS is starting to limit what comes next.


It is often a strong fit for organisations managing multiple brands, markets, languages or digital channels. It also suits teams that need tailored editorial workflows, reusable content, ecommerce connections, custom integrations or frequent product development.


For a simple brochure website, it may be more platform than you need. The right decision comes down to content complexity, internal capability, integration requirements, growth plans and total cost of ownership.


We help you weigh those factors honestly before recommending a platform. If Sanity fits, we define how to make it work. If another approach makes more sense, we will say so.


Our Sanity versus traditional CMS comparison breaks down the differences in more detail.

How we deliver a Sanity CMS project

1. Discover and define


We align on your audiences, business goals, content operations, technical requirements and measures of success. If you already have a platform, we also review the current codebase, content model, integrations and performance.


2. Architect the experience


We plan the customer experience, content model, editorial workflows, frontend architecture and integration approach. The important decisions are tested before the full build begins.


3. Build and integrate


Our designers and developers create the frontend, configure Sanity Studio and connect the platforms and services you need. Quality assurance, accessibility, SEO and performance are built into delivery from the start.


4. Migrate and validate


When migration is part of the project, we transfer and test content against the agreed model. Redirects, metadata, tracking, forms, permissions, integrations and publishing workflows are validated before launch.


5. Launch and improve


We support the release, monitor the platform and use real performance data to guide what happens next. New components, integrations and content capabilities can be introduced as your organisation evolves.


Make your digital experience your competitive advantage

03

Yes. Flight can migrate content and functionality from a traditional, legacy or headless CMS to Sanity. We begin with an audit and migration plan, then map the content, URLs, metadata, media, integrations and publishing workflows before testing the new platform and supporting the launch.


Our SEO and migration strategy helps protect important URLs, content relationships, search visibility and measurement throughout the move.


04

SEO is included in migration planning and quality assurance from the beginning. This covers content and URL mapping, redirects, metadata, headings, internal links, canonicals, structured data, crawlability, XML sitemaps, analytics and post launch monitoring.


No migration can guarantee unchanged rankings, but careful planning helps remove avoidable risks and gives your team a stronger foundation after launch.


05

Yes. Sanity is designed to work within a composable technology stack. Flight can connect it with Shopify, modern frontend frameworks, analytics, search tools, customer platforms and custom APIs.
