A Composable Stack, Without the Compromise

Vercel and Sanity have formalized a strategic partnership around what they call the Composable Content Cloud, pairing Sanity's headless CMS with Vercel's Frontend Cloud. The pitch is straightforward: teams get the flexibility of a decoupled architecture without surrendering content velocity or developer experience.

The two companies already have a history of joint development, including work on Visual Editing and embedding Sanity Studio inside Next.js applications. The partnership extends that collaboration into a more formal alliance, with shared customers like Loom, Morning Brew, and Takeda already running production stacks on both platforms.

"Vercel and Sanity are pioneers in developing cutting-edge solutions to help teams thrive in the composable era. We're excited to offer our customers continued value through this partnership, as they move on from legacy ways of working with digital experiences."
— Magnus Hillestad, CEO and Co-Founder of Sanity

Why Teams Are Going Composable

The underlying argument for a composable web stack is that decoupling frontend and backend removes the constraints of monolithic platforms. For development teams, that separation translates into faster release cycles and the freedom to build more dynamic, conversion-focused user experiences without touching the content layer.

Sanity contributes a content backend that is meant to be fully customizable, allowing teams to tailor the editing environment to their own workflows. Vercel, on the other hand, brings the infrastructure for performance-centric frontends, with an emphasis on measurable metrics like page load speed and time-to-first-byte.

The joint offering is also being positioned as a way to future-proof architecture decisions. The intended effect: site updates happen without full redeployments, and growth isn't gated by the limits of an older CMS or backend.

Toolkit Highlights

  • Templates: Pre-built Vercel + Sanity solutions are available to jumpstart app development.
  • Visual Editing: A click from the Preview Deployment interface takes you directly to the relevant content in Sanity Studio.
  • Incremental Static Regeneration (ISR): Create or update content without a site redeploy.

A Case for the Migration Path

Loom, the video communication platform, provides a concrete example of the migration away from monolithic architecture. The company moved its stack to Sanity, Next.js, and Vercel, enabling its engineering and marketing teams to operate in parallel rather than in sequence.

Marketers on Loom's team can self-serve content updates in Sanity while engineers push new designs or features independently through Next.js. As Loom senior software engineer Tatiana Mac puts it: "The engineering team can work on a completely separate feature or implement new designs using Next.js—all while sharing our work throughout the process."
