Draft Mode is a new feature on Vercel that allows users to see their latest content changes before they're published, making it easier to review and edit in real-time. This feature is integrated with Visual Editing, which enables real-time content editing for headless Content Management Systems (CMSes). With Draft Mode, users can easily server-render previews of static pages, protect unpublished content from being viewed publicly, and integrate with any headless provider of their choice. Additionally, the feature allows for unpublished draft posts that bypass Incremental Static Regeneration (ISR) and are not cached, making it easier to collaborate on website content without involving developers. The Visual Editing feature is now in public beta for Pro and Enterprise teams, and more CMSes have adopted the content source-mapping technology to enable this functionality.
