12 Best Sanity CMS Development Agencies in 2026

That makes it worth checking the Sanity experience before hiring a development agency. A team that has worked with the platform should know how to structure content for reuse, configure Sanity Studio for editors, connect the frontend and other business systems, and plan migrations without carrying old content problems into the new setup.

The challenge is finding that experience. Many companies offer headless CMS development, but their Sanity experience varies considerably. Some focus on complex enterprise platforms, while others suit marketing websites, e-commerce projects, or smaller product teams.

We reviewed agencies with publicly available Sanity services and project experience to narrow down the options. This guide compares 12 Sanity CMS development agencies in 2026, including what they offer, their published Sanity work, and the types of projects they are best suited for.

How We Selected These Sanity Development Agencies

We did not select agencies based only on whether they mention Sanity on a service page. We looked for public evidence of their experience with the platform and the types of Sanity projects they have worked on.

Our review focused on published Sanity projects and case studies, Sanity development services, frontend experience, migrations, integrations, and Studio customization. We also considered the technologies each agency works with and whether those skills match the requirements of a complete Sanity project.

We used company websites and public case studies as our main sources. We also checked public company profiles and Sanity's agency listings where additional information was needed.

The final list is not based on a single score. We selected agencies with different strengths so businesses can compare them based on their project needs, from marketing websites and e-commerce builds to migrations and larger multi-site projects.

Sanity CMS Agencies at a Glance

The agencies on this list work with different types of Sanity projects. Some have experience with large content migrations and enterprise websites, while others focus on e-commerce, marketing platforms, or ongoing website development. The comparison below shows their main strengths, technology stacks, and publicly documented Sanity work.

12 Best Sanity CMS Development Companies

Choosing a Sanity development company depends on what you need to build. A team experienced in large CMS migrations may not be the best fit for a smaller marketing website, while an e-commerce project may require deeper experience with product data and third-party integrations.

The agencies below have different areas of expertise and publicly documented Sanity experience. We look at their services, notable Sanity work, and the types of projects they are best suited for.

What a Sanity CMS Development Agency Should Deliver

Before hiring a Sanity agency, check what the team will deliver. The project should cover the website and the tools your staff will use to manage its content.

A complete Sanity project should have:

• Content modeling: Defined content types, fields, and relationships between pages, products, or other content.
• Studio customization: Editing fields, page previews, and publishing permissions based on your team's work.
• Frontend development: A working website that displays Sanity content correctly across desktop and mobile devices.
• Integrations: Connections to required systems, such as Shopify, search tools, or a CRM.
• Content migration: Existing content moved and checked, with old URLs redirected where needed.
• Editor training: Instructions and practical training for creating, updating, and publishing content.
• Post-launch support: A clear agreement covering bug fixes, updates, and technical support after launch.

Ask the agency to list these deliverables in its proposal, along with the work it will test before launch. For a detailed explanation, read our Sanity CMS development guide.

How to Choose the Right Sanity Agency for Your Project

Start with the agency's Sanity case studies. Look for projects close to what you need. If you are moving thousands of pages from an old CMS, experience with a small marketing website is not enough. Check what the agency built, how much content it moved, which systems it connected, and what problems it solved.

Next, find out who will work on your project. Ask whether the team has experience with your existing stack, such as Next.js, Shopify, or other systems that need to connect with Sanity. Also ask whether the developers involved in early discussions will stay on the project.

Compare proposals against the same requirements. Check what each price covers, the expected timeline, and how changes to the original scope are charged. Clarify subscription fees, hosting, content migration, and ongoing support before development starts.

It is also worth asking for a short Sanity Studio demonstration. See how an editor creates a page, changes content, previews it, and publishes it. This gives your team a better idea of what day-to-day content management will look like.

Finally, check recent client reviews for communication, deadlines, and post-launch support. Shortlist two or three agencies and give them the same project requirements. This makes their approach, timeline, and cost much easier to compare.

Summing It Up

The right Sanity agency depends on your project's needs. A large CMS migration needs different experience than a marketing website or an e-commerce platform. Start with agencies that have completed similar Sanity projects, then compare their approach, timeline, cost, and ongoing support.

The 12 agencies in this list have different strengths. Their public case studies give you a starting point for deciding which teams are worth discussing your project with.
