Content Management System that was originally written in 2013, based on Zend Framework 1, now wrapped in Laravel application, available as Open Source project on Github...
The base idea of the software is to be able to design the website in the admin panel, and do it in visual way, having the CMS in the background which will take care of the functionality, while the front should be 100% customizable right there in the admin panel, and being able to change the looks very quickly to something quite different with a few clicks, but also can have greater control by adding CSS and JS on the fly...

Have the designer and the frontend developer in one person, from the admin panel, in the future it could mean that you can skip designing in Photoshop or Figma, and design directly on your website installation.

After a template is designed and available for export, it can be uploaded to some other installation of IDE21.
