Sanity with Webflow

Sanity with Webflow

This one is for a specific shape of team: content lives in Sanity because the product needs it there too, but the marketing site should stay something marketing can edit. Sanity keeps the content, Webflow keeps the site, and a sync keeps them honest.

What the integration covers

What syncs, and what needs a decision.

Wired up

  • Sanity documents into Webflow collections, on publish rather than on a timer
  • Portable Text converted to the rich text Webflow's CMS actually accepts
  • References resolved in order, because Webflow needs the target published first
  • Assets re-hosted on Webflow rather than hot-linked from Sanity's CDN
  • Deletes and unpublishes propagated, so nothing outlives its source

Flagged upfront

  • Webflow's CMS caps at 20,000 items and 40 collections on the Premium plan, so a large Sanity dataset is filtered rather than mirrored whole
  • Portable Text is structured data and Webflow rich text is HTML, so the conversion is a build decision, not a field mapping
  • Webflow publishes at most once a minute and its API is rate limited, so a bulk sync is paced rather than fired
  • Two editing surfaces means one has to win; if Sanity is the source, the Designer stops being where content changes

The honest framing is that this is not a migration. Sanity stays where it is, keeps its schema and its editing experience, and Webflow becomes a rendering surface with a copy of the content. If the goal is to leave Sanity, this is not that project.

Two things decide whether the sync stays simple. Portable Text is Sanity’s structured representation of rich content, and Webflow’s CMS wants HTML — so somebody has to decide what a custom block becomes on the way across, and that decision is code, not configuration. And Webflow’s reference fields need the item being pointed at to exist and be published already, which forces the sync into passes rather than one loop.

Where this works well is a team that already treats Sanity as infrastructure. Where it works badly is a team hoping to edit in both places.
