Rocket Maintenance Mode & Coming Soon Page

Easy to use and almost fully customizable



Does what it says - creates a maintenance page, but everything is pretty much locked down unless you upgrade to the premium version, which the plugin authors annoyingly let you know everywhere. Makes you think that they're just trying to make a buck. Can't even change the font color.
There are better plugins that do exactly this that are much more configurable. I'd keep looking.



Much better, more configurable plugins out there to do this

Create great looking Maintenance Mode Page or Coming Soon Page that sets up in minutes.
