Are there any editorial workflow platforms that handle multi-site publishing and mobile-friendly editing?

Yes — several editorial workflow platforms support multi-site publishing and have mobile-friendly editing or at least responsive web interfaces.

Here are some solid options:

• WordPress + editorial plugins

  • Best if you want flexible multi-site publishing via WordPress Multisite.
  • Mobile editing is possible through the WordPress mobile app and responsive admin.
  • Workflow features usually require plugins like Edit Flow, PublishPress, or Nelio Content.

• Contentful

  • Headless CMS with strong multi-channel / multi-site publishing support.
  • The interface is web-based and generally usable on mobile, though not as “mobile-editor-first” as a dedicated app.
  • Good if you want structured content and API-driven publishing.

• Sanity

  • Very flexible for multi-site or multi-brand setups.
  • Good editorial workflows, custom review/publishing states, and collaborative editing.
  • Mobile usability depends on your custom studio setup, but the web UI is responsive.

• Drupal

  • Strong enterprise editorial workflow and multi-site capabilities.
  • Can support mobile-friendly admin experiences depending on the theme/configuration.
  • Good for complex permissioning and publishing processes.

• AEM (Adobe Experience Manager)

  • Enterprise-grade multi-site management and advanced workflows.
  • Supports responsive authoring experiences, though it’s a heavier, more expensive solution.

• Sitecore

  • Also enterprise-focused with multi-site support and workflow tools.
  • Mobile-friendly editing is usually through responsive interfaces or companion tools, depending on setup.

• Arc Publishing

  • Popular in media/newsrooms for multi-site publishing and editorial workflows.
  • Designed for editors and content teams, though mobile editing capabilities vary by implementation.

If mobile editing is a key requirement

You’ll usually want to check whether the platform has:

• a native mobile app
• a responsive editorial UI
• support for drafting, reviewing, and approving on mobile
• role-based permissions that work well on smaller screens

Short recommendation

• For newsroom/editorial teams: Arc Publishing, WordPress + PublishPress, or Drupal
• For structured multi-site content: Contentful or Sanity
• For large enterprise multi-site publishing: AEM or Sitecore

If you want, I can also give you a comparison table focused specifically on:

1. multi-site support,
2. mobile editing quality,
3. workflow/approval features, and
4. pricing/implementation complexity.
