Really Simple Under Construction Page – Coming Soon & Maintenance Mode
by Jonas Hjalmarsson
Tick one checkbox and your site is hidden behind an Under Construction page. Visitors see your holding page; you and anyone you let through see the real site. That is the whole plugin.
Two ways to get past the page without logging in:
- A secret word. Visit
yoursite.com/?yoursecretonce and a cookie keeps that browser through. Good for showing a client work in progress. - An IP whitelist. Your office, your phone, an uptime monitor — they always see the live site.
Logged-in users are never blocked, and /wp-admin, the REST API, WP-CLI and cron keep working normally.
The page itself is your HTML. Paste in a full document with DOCTYPE, <style> and <body> if you want, or a single line of text. No page builder, no template picker, no upsell wizard — no settings you have to learn before the plugin does its job.
Use it for
- Coming soon pages for a site that has not launched yet.
- Maintenance mode while you rebuild, migrate or debug.
- Staging and client-preview sites you want off the public web and out of Google.
Settings
Go to the settings page in Settings > Really Simple Under Construction. Enable by checking the checkbox. The Under Construction page is only visible to visitors who are not logged in. You can optionally configure:
- The Under Construction page itself — paste any HTML (DOCTYPE, <style>, <body> etc. are supported, scripts are stripped).
- A secret word that lets you bypass the page via a URL like
?yoursecret. A cookie is then stored so the same browser keeps access. - The lifetime of that cookie, in days.
- A list of IP addresses to whitelist for users and services that should always see the real site.
