How paid CMS helps save on ordering SEO

How paid CMS helps save on ordering SEO 
3r3-31. In this article I will talk about why we offer our customers who have ordered the development of the site to create it on a paid CMS. And at the same time I will reveal the logic of CMS participation in the formation of the total cost of search engine promotion.

Ten things you can do with GraalVM  
From the translator: GraalVM is a new, interesting technology, but on Habré there are not many articles on it that could show examples of the possibilities of Graal.

In principle, the problem is not new and has many different solutions. But for a number of reasons I stopped at writing my own plugin.
 
It looks like this:
