Vercel vs Dataweavers:where should your headless front end run?
Moving Sitecore or Optimizely to a headless Next.js front end raises one question fast: where does that front end run? Vercel is a developer front-end cloud built by the creators of Next.js. Dataweavers Arc is a managed headless platform that runs the front end, APIs and operations inside your own Azure tenant.

TL;DR
The honest short answer
If your developers want the best Next.js experience, self-serve plans, preview deployments for every change and built-in performance data, and your security team accepts a multi-tenant SaaS host, Vercel is the stronger front-end platform. It is also a common home for SitecoreAI front ends.
If security or procurement requires the front end and its data to stay in your own Azure tenant, or you want one team to run Sitecore XP/XM or Optimizely, the front end and disaster recovery around the clock, Dataweavers is the better fit. It is a managed operator, not a general-purpose host.
Choose Dataweavers if
The platform must run in your Azure tenant
Arc runs the front end, APIs and operations in your tenant, with a 24/7 operations team, and Fusion can run the Sitecore or Optimizely back end too.

When to choose each
Choose Vercel when
You want the fastest path for a Next.js team
- Your security and cloud teams approve a SaaS front-end host
- Your CMS is SaaS, such as SitecoreAI, so there is no back end to operate
- Developers want a preview for every pull request and real-user performance data
- You want to start on a self-serve plan and scale without a contract
- You run several Next.js sites, not only CMS-driven ones
Choose Dataweavers when
Control and operations matter more than self-serve speed
- Policy requires the front end and its data to stay in your own Azure tenant
- You still run Sitecore XP/XM or Optimizely and want one operator for back end and front end
- You need private connections to internal systems that should not leave Azure
- You want a 24/7 operations team and disaster recovery without building them
- You are moving from XP/XM to SitecoreAI one site at a time
Combining them is possible
Dataweavers and Vercel can share one estate when each owns a different layer.
Dataweavers for operations, Vercel for the front end
On SitecoreAI, you can keep the Next.js front end on Vercel and add Dataweavers Spark for on-demand publishing. Spark supports the Sitecore Content SDK with Next.js 16 on Vercel or on Arc.
Scenario: a retailer moves its main brand site to SitecoreAI with a Next.js front end on Vercel, and uses Spark so pages update the moment authors publish. A second site that handles member data stays on Sitecore XP, operated by Dataweavers in the company's Azure tenant until its own migration.
Check the limits before you plan it. Spark's support for Sitecore JSS on XP/XM requires an Arc-hosted front end, so an XP/XM site with a Vercel front end needs its own revalidation approach. Two platforms also mean two contracts and two operating models.
If you need to switch
Both run standard Next.js applications, so moving the front end is mostly a hosting and pipeline project. The CMS and content stay where they are.
Vercel to Dataweavers Arc
Typical when security requires your own Azure tenant
- List Vercel-specific features in use, such as Fluid compute settings, flags, analytics and edge middleware
- Provision Arc in your Azure tenant and connect the repository to its deploy pipelines
- Move environment variables, redirects and headers, and set up publishing with Spark or webhooks
- Test rendering, caching and integrations on a staging hostname before changing DNS
Main effort driver: Vercel-specific features and the integrations that must move into Azure
Dataweavers Arc to Vercel
Typical after a move to SitecoreAI
- Confirm your security team approves a SaaS front-end host
- Import the repository into Vercel and copy environment variables
- Replace private Azure connections with APIs reachable from Vercel
- Set up revalidation, with Spark if you stay on the Content SDK, then validate on a preview deployment and switch DNS
Main effort driver: private integrations and who takes over 24/7 monitoring
Common questions
Can a Sitecore front end run on Vercel?
Yes. Vercel is a common rendering host for Sitecore Next.js front ends, especially on SitecoreAI. Sitecore's guidance on self-hosting in Azure notes that hosting providers like Vercel and Netlify handle much of the configuration work. Read Netlify vs Vercel if you are choosing between the two.
Why would a company choose Dataweavers over Vercel for the front end?
Usually because of policy. Some security and cloud teams require every workload and its data in their own Azure tenant, or need private connections to internal systems. Dataweavers runs the front end there and operates it 24/7. See our Dataweavers page.
Can Dataweavers host any website?
No. Arc is purpose-built for headless Sitecore, Optimizely and Contentstack. For a general marketing site or app without one of those platforms, a front-end cloud such as Vercel or Netlify is the usual choice.
Does Dataweavers Spark work with Vercel?
Yes, for SitecoreAI front ends built with the Sitecore Content SDK on Next.js 16. Spark's support for Sitecore JSS on XP/XM applies when the front end runs on Arc.
Which one is cheaper?
They price different things. Vercel starts at $20 per month on Pro, plus $20 per extra deploying seat and metered usage. Dataweavers is quote-based and includes operations, monitoring and disaster recovery, with Azure consumption in your tenant. Compare total cost, including the people you would otherwise need to run the platform.
Is Sengo a Vercel partner?
No. Sengo delivers projects on Vercel without a partnership. Sengo is an official Dataweavers partner, a Netlify partner and a Sitecore partner.
