Free coming soon/maintenance mode plugin for Divi
The Divi Coming Soon plugin is a free plugin that allows you to use the Divi Builder to create your coming soon page, maintenance mode pages, and under construction page.
A coming soon page for Divi allows you to hide your website to the public when you are in the process of building a new site, making changes to the site or performing updates. When you activate your Coming soon page in the Settings, all website traffic to your site, except logged in Admins and Editors), will automatically be re-directed to the coming soon page of your choice.
Divi Life also offers the Coming Soon Layouts for Divi, which is a premium Divi layout pack with 5 pre-designed coming soon templates to load into your Divi Builder.
