JavaScript-rendered content — The app analyses the HTML returned by the webpage's server and does not execute JavaScript. Content that is added or modified by JavaScript after the page loads may not be detected.
Website blocking — Some websites, CDNs, firewalls, or bot-protection systems may block automated requests, meaning the page cannot always be analysed.
Restricted pages — Pages that require authentication, a login, or other restricted access cannot be analysed.
Dynamic or personalised content — Content that is generated based on cookies, user sessions, location, or other browser-specific conditions may differ from what the app receives.
External resources — Some checks involving external URLs may be affected if those resources block automated requests or are unavailable.
