# Workflow SDK now runs natively in Nitro v3

By Steven Van · 2026-06-13

Workflow SDK's beta Nitro v3 integration shares one bundled runtime, adds a /\_workflow debug UI, and tree-shakes unused code from builds.

Workflow SDK's native integration with Nitro v3 is now in beta, letting workflow steps run inside the same bundled runtime as the rest of a [Vercel](<https://creatorstoolbox.com/tools/vercel>) app instead of a separate bundle. Nitro's useStorage() and other server-side APIs now work directly inside "use step" functions.

- The Nitro dev server serves the workflow web UI at /\_workflow, so runs can be inspected, monitored, and debugged in the browser.

- Workflow routes are bundled by Nitro as part of the app build, with dependency tracing and tree-shaking of unused code, resulting in faster builds and smaller bundles.

Details on setting it up are in the [Nitro integration guide](<https://workflow-sdk.dev/v5/docs/getting-started/nitro>).
