Optional external enrichment — popularity, traffic, and DNS signals that complement the first-party scan. Fetched on demand from an external provider; it is not part of the live scan.

WordPress / CMS Details

No strong WordPress signal

No strong WordPress signal was found in the public HTML/resources.

WordPress sites can hide public CMS traces behind caching, headless frontends, or bundled assets.

Scan coverage

What this report used

Static fetch
Used · HTML, headers, metadata, robots.txt, and sitemap.xml
Rendered DOM
Disabled · Set ENABLE_PLAYWRIGHT=1 to enable rendered DOM scanning.
axe-core

Lighthouse
Disabled · Set ENABLE_LIGHTHOUSE=1 to enable Lighthouse CLI audits.

This was a fast static scan of the public HTML, headers, robots.txt, and sitemap. Deeper rendered-DOM, lab (Lighthouse), and axe-core checks are optional and off for this report — so any empty section below reflects that boundary, not a clean bill of health.

Detection Method

Multi-signal scan, not logo guessing.

Themerella uses a self-owned static scanner that combines HTML, resources, headers, metadata, CSS-class hints, robots.txt, and sitemap.xml. Enable Playwright to add rendered DOM, runtime globals, dynamic network responses, axe, and Lighthouse.
