What Is Content Preview in a CMS?
BeginnerQuick Answer
TL;DR
Content preview in a CMS lets editors see how their content will look on the live website before publishing. It bridges the gap between the editing interface and the final rendered output, helping catch formatting issues, broken layouts, and visual problems before they reach visitors. Preview ranges from basic rendered views inside the CMS to full-fidelity previews that render content through the actual frontend framework and design system.
Key Takeaways
- Content preview shows editors a rendered view of their draft content before it goes live.
- Basic preview renders content inside the CMS; full-fidelity preview renders through the actual frontend (Next.js, Nuxt, etc.) with real styles and components.
- Device preview (desktop, mobile, tablet) helps catch responsive layout issues before publishing.
- Headless CMS architectures require extra setup for preview because the editing interface and frontend are separate systems.
- Draft preview should show unpublished content without exposing it to public visitors — typically via a secret preview token.
