How the CMS & Theme Detector Works
01
Enter a Domain
Type any domain or upload a CSV file with up to 1,000 domains. No login or signup needed.
02
We Read the Source
Our tool fetches each site's publicly visible HTML and HTTP headers to identify CMS signatures, theme paths, plugin references, and footer text.
03
Get Full Results
CMS platform, theme name, plugins, CDN usage, and footer notes — displayed instantly for single domains or exported to Excel for bulk scans.
Supported CMS Platforms
Our detector identifies the following platforms from publicly visible signals in the page source and HTTP headers:
WordPress
Shopify
Wix
Squarespace
Webflow
Drupal
Joomla
Ghost
Magento
OpenCart
PrestaShop
HubSpot CMS
Blogger
Static HTML
For WordPress sites the tool also detects the active theme name and installed plugins that leave visible traces in the page HTML.
What Each Column Means
CMS / Platform
The content management system or website builder the site is built on. For WordPress sites this includes the version number where detectable — e.g. WordPress 6.9.4.
Theme
The active WordPress theme name. Detected from stylesheet URL references in the page source. For non-WordPress sites this column will show a dash.
Plugins
All WordPress plugins detectable from the public page source — including Elementor, WooCommerce, Yoast SEO, Contact Form 7, WPForms, and many more. Plugins that load only via JavaScript after page load may not be detectable.
Cloudflare
Whether the site is served through Cloudflare's CDN. A Yes means the site's real server IP is hidden behind Cloudflare. Useful for technical audits and infrastructure analysis.
Footer Notes
Any attribution text found in the site footer — agency credits, builder credits, copyright text, or "powered by" attributions. Useful for identifying sites built by the same agency or using the same template.
Frequently Asked Questions
How does the tool detect CMS without admin access?+
Every CMS leaves identifiable signatures in publicly visible HTML and HTTP headers — WordPress uses /wp-content/ paths, Shopify uses cdn.shopify.com, Wix leaves its own JavaScript references. Our tool reads these public signals the same way any browser would.
Is this tool completely free?+
Yes. Single domain detection is unlimited and completely free. CSV bulk scanning supports up to 1,000 domains per upload with full Excel export at no cost and no account required.
How do I format the CSV file?+
Create a plain text or CSV file with one domain per line. You can include or omit https:// — the tool strips it automatically. Example: flamingbullz.com on line 1, example.com on line 2, and so on. Maximum 1,000 domains per file.
Can all plugins be detected?+
We detect plugins that leave visible references in the page HTML — stylesheet or script paths, body classes, or markup signatures. Some plugins deliberately hide their presence or load entirely via JavaScript after the initial page load and will not be detected. Well-known plugins like Elementor, WooCommerce, and Yoast are reliably detected.
What does the Footer Notes column show?+
Footer Notes captures any attribution text found in the site footer — for example "Powered by X Agency", "Designed by Y Studio", "Built with Elementor", or copyright text. This is useful for identifying sites built by the same developer or agency, or for auditing a network of sites for shared builder patterns.
What does the batch size option do?+
Batch size controls how many domains are scanned before the tool pauses briefly. Smaller batches (5-10) are gentler and less likely to hit server rate limits. Larger batches (50 or all at once) are faster but may trigger rate limiting on some hosting environments. For large lists of 500+ domains we recommend 25 at a time.
