Requirements

• Joomla 4.0 or later — tested through the current 6.x. Joomla 3 is not supported.
• PHP 8.1–8.4 with the dom, libxml, mbstring, json and zip extensions.
• The site being scanned must be reachable from its own server over HTTP(S).

No external services

The extension runs inside your Joomla administrator. There is no separate server, database or hosting requirement beyond what your Joomla install already needs. The free edition’s only outbound request is Joomla’s standard “Check for Updates”; Pro adds an hourly licence check to store.lyzerslab.com and nothing else.
