Very light, clean and simple look. Much appreciated.

Extremely simple, reliable, fast. It looks clean and official, and there's no upsell. The code is easy to modify if you want to change the message. I've officially moved from a formerly minimal maintenance mode plugin that added lots of crap I didn't want or need. Thank you for this!

I have been looking for something this super lightweight for a very long time. Slim Maintenance Mode is the only lightweight plugin without any bloat. It works great and simple. This will be part of my workflow from now on. Thank you so much.

Does exactly what I expect a maintenance plugin to do: show a maintenance message to users who're not logged in fix cache compatibility issues automatically send a 503 (Service Unavailable) HTTP response code No settings needed. Thanks!
