Sometimes you don’t need (or want) to shut down the entire frontend of the site during maintenance. Unlike the default WordPress maintenance mode, this plugin allows your site to stay running.
<ul>
<li>Any non-Administrator will be logged out</li>
<li>Comments will be closed (disabled) on all posts</li>
</ul>
This plugin does not interact with, prevent, or override WordPress’s maintenance mode. It’s complementary.

As a web developer working with WordPress almost every day, very often I came across problem that If I wanted simple maintenance plugin to do some updates on my or client’s website, I came across all these useless and overcomplicated plugins until I decided that I’ll make one myself which will be the one I’ll be confident and happy to use with ease.
<a href="https://plugins.itsluk.as/maintenance-mode/" rel="nofollow ugc">Maintenance Mode</a> is very simple and it’s using WordPress’s wp_die() function which is core function of WordPress, which makes this plugin feel and work as a part of WordPress core. There is settings page under “Settings” in the main wp-admin menu where you can enable maintenance mode or change content using WYSIWYG editor so you can also add pictures, links etc. When activated and logged in as admin, you can see website as usual, rest of the users / visitors can see maintenance mode. You can see the maintenance mode as admin in preview mode using preview link on the settings page or simply open website in private mode or different browser to double check if it’s enabled and working. There is also indicator in admin bar that changes colour to red when maintenance mode is enabled.
Features:
<ul>
<li>Simplicity – Built to be as simple as possible. Easy to use.</li>
<li>Customisable – WYSIWYG available in full glory. You can add images and other media including links and pretty much everything you can do with WYSIWYG. Text / Code tab is available too for custom markup.</li>
<li>Works on mobile – Because of it’s simplicity, maintenance mode works very well on mobile devices.</li>
<li>NO ADS – No ads. Seriously.</li>
<li>NO PAID UPGRADES – No paid upgrades. Seriously.</li>
<li>Updates – Regular updates and maintenance.</li>
<li>Support – Support button available.</li>
<li>Preview – Preview button available.</li>
<li>Compact – It’s developed to be as compact as possible.</li>
<li>Role Control – User Role control is available since 2.0</li>
<li>Optional widgets – Optionally add widgets above and/or below the content</li>
<li>Optional style sheet – Optionally add a custom style sheet</li>
<li>Optional ability to add code snippet – Optionally add a code snippet to the page.</li>
<li>Support for Analytify plugin – If you use the Analytify plugin, you can automatically insert the Google Analytics tracking code.</li>
</ul>

Maintenance Mode

WP 5.1.1. Does not work. Activated but no settings pages available. Can't even get to settings via Plugins -> Maintenance Mode -> Settings.

Does not work

... a non-bloated, hassle-free maintenance plugin.

Thank you.

Finally...

Very simple Maintenance Mode & Coming soon page using default Wordpress markup with no ads or paid upgrades.
