It allows for search bots to access the site even during maintenance, preventing any adverse effects on your website's search engine rankings. This feature ensures that your SEO efforts are not undone and helps in maintaining a stable online presence.

Another commendable feature of this plugin is the ease of toggling the maintenance mode on and off, either through console commands or via the back office in Sylius. This dual functionality ensures that you can quickly initiate or conclude maintenance periods without going through a lengthy process, saving time and effort.

Additionally, it permits customization to a great extent, allowing you to tailor messages and settings directly from the Sylius back office. It facilitates creating a more personal and branded message for your visitors, ensuring a seamless integration with your existing website design and brand language.

In terms of compatibility, the plugin is designed to work harmoniously with PHP version 8.0 and above, and is compatible with Sylius version 1.10 and later, promising stable and reliable performance.
