Maintenance & Coming Soon Pages

Two single-file PHP pages - a maintenance page with a real 503 response and an IP bypass list, and a pre-launch coming soon page - both dark-themed and ready to drop in.

Demo

Open either page directly to see it in action.

A screenshot will be added here soon.

What's included

• Real 503 response - maintenance.php sends 503 Service Unavailable with a Retry-After header, so search engines treat the downtime as temporary instead of dropping pages from the index.
• IP bypass list - an optional array of IPs that skip the maintenance page entirely, for testing the live site while it's down for everyone else.
• noindex on both pages - X-Robots-Tag: noindex, nofollow so neither placeholder gets indexed while it's live.
• Dark theme, single file - inline styles, no external stylesheet, no build step, no dependencies beyond Google Fonts.
• Config-driven text - headline, message, and (for the maintenance page) ETA are all easy to find and edit.
• Responsive - the card and type scale down cleanly on mobile.

Usage

// maintenance.php
$maintenance_bypass_ips = [
    // '123.123.123.123',
];
header('Retry-After: 3600'); // seconds until back online

// coming-soon.php
$comingSoonConfig = [
    'headline' => 'Something great is coming',
    'message'  => 'We're working hard behind the scenes...',
];

To actually take a site offline, route requests to maintenance.php at the server level (rename it to index.php behind a rewrite rule, or use your host's maintenance-mode setting) rather than just linking to it.
