Solution
A custom plugin was built to extend OctoberCMS
This plugin provides pages, templates, strings, partials, previews and version control using the native OctoberCMS functions.
A dynamic website, with complete separation of presentation and data is provided. The HTML editor works with TWIG, which is used in the building of pages and the frontend where the TWIG template is rendered with data through AJAX calls to an API.
A static website could be built with the CMS only.
The solution is fast, robust, reliable and easy to maintain.
