Why not CMS?
Security
CMS
Since the bulk of commercial sites are made on the popular boxed versions of CMS and their internal structure is open for general viewing, they are the most prone to targeted attacks (special bots are launched that look for vulnerabilities and crack such sites in large numbers).
Framework
The process of building a site using frameworks is controlled by the developer and makes it possible to detect and eliminate all potentially dangerous security holes. In this aspect, the solutions on the framework are much superior to those on the CMS.
Functionality
CMS
The functionality of sites based on CMS is limited by existing templates. And although experienced developers can make minor changes to expand the functionality, any step towards uniqueness often turns into a headache.
Framework
Sites based on the frameworks have a much greater degree of individualization for the implementation of specific tasks. Developers always have the opportunity to implement even the most non-standard solutions, using various methods.
Performance
CMS
In pursuit of versatility and the desire to please everyone, CMS developers lay down many functions, most of which are not needed for one project. The result is a lot of unused code. Excessive functionality creates an unjustified load on the server, which reduces the performance of the site and its loading time.
Framework
Decisions on frameworks, as a rule, function much faster and withstand a greater load than CMS: fewer unnecessary elements and modules - faster work. A site on CMS is always inferior in performance to a well-written site on the Framework.
The core
CMS
In order to slightly correct or modify any part of the site, you have to deal with the system device. Rewriting basic CMS processes takes longer than the same work originally done on the Framework.
