Maintenance Redirect is a versatile WordPress plugin designed for developers and designers to manage site visibility during updates. It allows clients to preview their sites before public access and temporarily hide content while undergoing significant changes. Administrators can control access settings easily, ensuring that only logged-in users with the right privileges can view the site, which can be adjusted using a filter hook. The plugin offers flexibility, enabling users to activate or deactivate the behavior without losing configurations, although deactivation is recommended when not in use.

The plugin supports two header types for redirection: ‘200 OK’ for sites in development and ‘503 Service Temporarily Unavailable’ for those taken offline for minor adjustments. Users can set up IP addresses to bypass maintenance mode, facilitating access for clients without individual keys. Notifications to users can be customized through simple messages, custom HTML pages, or redirects to static HTML pages uploaded externally, allowing for seamless communication about maintenance status.
