WP Maintenance Mode is a free and open source “maintenance mode” plugin that packs a lot of features in an easy to use interface. Unlike the basic maintenance functionality available in WordPress, WP Maintenance Mode adds custom text, design options, a countdown option and more.
The plugin can also be used as a coming soon page. Instead of directing visitors to a generic landing page, WP Maintenance Mode has all the functionality needed to establish an effective communication medium with a site’s visitors.
The latest WP Maintenance Mode version adds a much-awaited feature, the chatbot.
