Couldn't Scan That Site
Something went wrong.
What We Look For
We scan public page source, scripts, and response headers for known platform and tool signatures across 19 categories.
CMS, eCommerce & Page Builders
WordPress, Webflow, HubSpot CMS, Shopify, BigCommerce, Magento, Squarespace, Wix, Framer, Duda, Craft CMS, Umbraco, Drupal, Joomla, Ghost, and more — plus WordPress theme, version, Elementor, Divi, Oxygen, Bricks, and other WordPress builders.
Analytics, Chat & Payments
Google Analytics, GTM, Meta/TikTok/Pinterest Pixels, Hotjar, Mixpanel, and more, plus live chat widgets (Intercom, Drift, Zendesk) and payment processors (Stripe, PayPal, Klarna).
JS/CSS Frameworks & SEO Tools
jQuery, React, Vue, Next.js, Bootstrap, Tailwind CSS, Google Fonts, and SEO plugins like Yoast and Rank Math.
Security & Server Signals
Security headers (HSTS, CSP, X-Frame-Options), reCAPTCHA/hCaptcha, plus server, CDN, IP, and hosting-provider signals from response headers.
Marketing & Conversion Tools
Email marketing platforms (Mailchimp, Klaviyo, ActiveCampaign), review/social-proof widgets (Trustpilot, Yotpo, Judge.me), and A/B testing or personalization tools (Optimizely, VWO, Google Optimize).
Frequently Asked Questions
Yes. There's no signup, no email required, and no limit on how many sites you can check.
We check real signals in the page's HTML, scripts, and response headers — but some sites hide or minify these signals, so results reflect what's publicly detectable, not a guaranteed complete list.
No — we focus on the platforms and tools businesses ask about most often, across 19 categories: CMS platforms and versions (WordPress, Webflow, HubSpot, Shopify, BigCommerce, Squarespace, Wix, Craft CMS, Umbraco, and more), WordPress themes, page builders, caching and performance plugins, analytics, email marketing, review/social-proof widgets, A/B testing tools, JS/CSS frameworks, fonts, SEO plugins, live chat widgets, payment processors, security signals, and basic page info (title, meta description, viewport).
Yes. You can check any publicly accessible URL — useful for researching what platform and tools a competitor uses.
This means we didn't find a recognizable signature for the CMS platforms we check. It usually means the site is custom-coded rather than built on a common CMS.
No. We scan the page live and don't save the URL or results anywhere.
