This plugin activates a maintenance page for your site, hiding the live content from visitors while you perform updates or changes. It is designed for site administrators and developers who need to work on a live site without disrupting its search engine rankings.

• SEO protection: Sends a '503 Service Unavailable' HTTP status to unauthenticated visitors, which instructs search engines to pause crawling and preserve your site's existing rankings.
• User access control: Logged-in administrators can view and use the site normally, while all other visitors see only the maintenance page.
• Multisite compatibility: Handles activation correctly on multisite installations, a common oversight in similar tools.
• Developer customization: Offers filters for developers to whitelist specific IP addresses or completely replace the default maintenance page template.
• Lightweight operation: Has no settings panel to configure; it is active immediately upon installation to reduce setup time.
