Verdict in one paragraph

Migration vs greenfield framing. Headless WordPress wins when there is existing WP content, an editorial team that lives in wp-admin, and you cannot retrain. Sanity wins for greenfield projects, structured-content briefs, and teams that want to leave the WordPress operational footprint behind. For a 12,000-site agency reality, the team is the deciding factor — pick by who edits, not by framework.

Decision criteria

  • Which is the right pick for migrating an existing WordPress site?

    Headless WordPress

    The editorial team keeps wp-admin. Content lives where it already lives. The migration is just a new front-end, not a new CMS.

  • Which is the right pick for a greenfield project?

    Sanity

    Schema-first content modelling, real-time collaboration, no operational overhead. Greenfield without WP legacy almost never picks WordPress in 2026.

  • Which has the better content modelling?

    Sanity

    Sanity's schema-as-code is a different category from WordPress custom post types + ACF. The modelling depth is real.

  • Which has the lower operational footprint?

    Sanity

    Sanity is hosted; you do not patch it, scale it, or worry about plugin conflicts. WordPress has real ongoing maintenance.

  • Which has the bigger plugin / extension ecosystem?

    Headless WordPress

    60,000+ WordPress plugins. Sanity has integrations and Studio plugins but the breadth is incomparable.

  • Which is easier for non-technical authors who already know WordPress?

    Headless WordPress

    Zero retraining. wp-admin is muscle memory. Sanity Studio is good but it is a new tool to learn.

What Headless WordPress is best for

  • WordPress sites migrating to a modern front-end without changing the editorial workflow
  • Editorial teams with WordPress muscle memory and no appetite for a new admin UI
  • Projects with significant WordPress content history (12,000-site agency reality)

What Sanity is best for

  • Editorial-heavy projects with custom content schemas
  • Teams that want collaborative real-time editing without engineering it
  • Projects with rich text that needs custom blocks (Portable Text)
  • Multi-channel publishing where content fans out to web + app + email
