Theoretical this is a great plugin allowing users to design and change their "Maintenance" page in Gutenberg.
But in reality it hung my WP admin upon activation.
And the site is not available. Too many re-directs.
Also the so called templates do install an extra plugin "Otter" which might be handy. But a little confusing.

I managed with a lot of effort to create a maintenance page but I can't find any instructions as to how to get the maintenance page to come up when someone comes to the site.

Unacceptable that it installed 3 plugins at least: a block manager, an image optimizer and the plugin you theoretically want to install. Don't get it close to your site... Still investigating what else it could have done :O !

Customisation and useful

Also it forces you to download other plugins.

Beware! Installed unasked and unnecessary plugins. Hope it didn't interfere with the source code – dangerous!

Works just fine.

This plug-in works as advertised. The landing page itself is lightweight while the offered customization option seem sufficient.

Great for a Maintenance or Coming Soon page and comes with several templates. I've used it for that purpose on a couple of sites, and I've taken advantage of the templates to build myself a Linktree/Carrd alternative on another site, and I just permanently leave LightStart on.

Please avoid. THEY ADD 4 seconds to my admin dashboard load time, just to get their advertisement business going... look below, two requests to "recommend plugin or theme"... Guys, ASK when you take 4 seconds out of my request time to recommend some stuff that I never asked for, especially not on the main admin page, from a little utility plugin.
GROSS. Guys like this ruin the web.
