Build Mode lets you put your WordPress site into maintenance mode or display a coming‑soon page / under‑construction page with one click. Instead of a generic message, you can select and display any page you’ve built — with the Block Editor, Classic Editor, or a page builder. Visitors will see your chosen maintenance or coming‑soon page, styled using your theme’s CSS and JS, while logged‑in administrators continue working behind the scenes.
When Build Mode is active, only the content area of your chosen maintenance page is displayed. The header, footer and navigation are automatically removed.
