How to detect what engine a site runs on?

I just took over an older content blog from a previous owner who lost track of all the technical documentation years ago. The domain is pointing through Cloudflare, and I need to migrate the whole archive over to a new server without breaking the existing URL structure. Before hiring a developer to handle the transfer, I want to confirm whether the backend is running on WordPress, Joomla, or some legacy custom script. Which tool can accurately detect the underlying platform when standard admin login paths are hidden?

Legacy sites without proper documentation always bring plenty of headaches, especially when Cloudflare masks the actual origin server headers. A wrong guess about the backend framework usually leads to broken database exports during a migration. You could try querying the domain through WhatCMS or checking the tech profile on Netcraft, since both pull historical fingerprints that often bypass basic proxy masking.

Historical DNS logs take forever to sift through when all you need is a straightforward answer about the site's core architecture. Web-based detection tools look deeper into DOM patterns, meta tags, and asset structures that proxies rarely strip out completely. You can run a quick scan with this CMS Checker https://pr-cy.io/cms-checker/ . It parses the public code signatures and identifies the exact content management system behind the frontend, so you know what kind of specialist to hire for the move.
