Top Priorities (5)

Sorted by impact
Critical: 1

Content-Security-Policy header is missing

Without a CSP, a single XSS bug can exfiltrate everything your users type — including credentials.

Security › Security Headers
Critical: 2

No Content-Security-Policy header found

Without a CSP, a single XSS bug can exfiltrate everything users type — credentials, payment data, session tokens.

Security › Content Security Policy
Critical: 3

2 button(s) with no accessible text

Buttons with no accessible text (icon-only, no aria-label) can't be activated by voice control or understood by screen readers.

Accessibility › Link & Button Quality
Critical: 4

2 image-only link(s) without alt text

Image-only links with no alt are unidentifiable to screen-reader users — link's destination is invisible.

Accessibility › Link & Button Quality
Critical: 5

No <main> landmark found

Without a <main> landmark, screen-reader users can't skip past the navigation to the page content — every page starts with re-reading the menu.

Accessibility › Landmark Structure
What fixing these means. Your site performs reasonably well, but a few targeted fixes could meaningfully improve results. Accessibility issues exclude users who rely on assistive technology — an estimated 15% of your potential audience. Addressing the critical issues below would have the most immediate impact on your user trust.
2 security gaps detected — browsers may warn visitors about your site.
3 accessibility issues exclude users who rely on assistive technology.

  • Page takes 13.1s to load

    → Optimize render-blocking resources, preload the hero image, and compress images
  • Page feels frozen for 938ms
    Clicks on the primary CTA are ignored while JavaScript runs
    → Break up long tasks; defer non-critical JavaScript to post-hydration
  • No HSTS header
    Returning visitors are briefly exposed to downgrade attacks on first request
    → Set Strict-Transport-Security: max-age=31536000; includeSubDomains
  • No Content-Security-Policy header
    Higher XSS blast radius — one compromised script can exfiltrate the checkout form
    → Ship a reporting-only CSP first, then enforce once violations are clean
  • Layout shifts during page load
    Content movement causes mis-clicks on CTAs and form fields
    → Add width/height to images; reserve space for late-loading embeds

Observations (2)

No build tool detected

A framework (HSTS) was detected but no bundler was identified. The build tool may not be detectable from output patterns, or the site may use the framework's built-in bundler.

Complex technology stack detected

9 technologies identified. A complex stack increases maintenance burden and attack surface. Consider whether all components are actively needed.
