About This Tool

The tool inventories cookies set by a target site by rendering the page in a headless browser, inspecting Set-Cookie headers and document.cookie after load, and deduplicating by domain and path. For each cookie, it records name, domain, path, expiry, size, and attributes (Secure, HttpOnly, SameSite). It distinguishes first-party cookies (same domain as the target) from third-party cookies (different domains) to reveal third-party scripts and trackers.
The analysis computes a privacy risk score and consent considerations. It flags cookies with long expirations, missing Secure or HttpOnly flags, SameSite=None, or third-party scope as higher risk, and it notes whether consent would normally be required under GDPR/CCPA. Outputs can be exported as JSON or CSV, with values redacted by default to protect sensitive data.
Use cases include preparing consent banners, validating data retention, reducing data exposure, and supporting privacy-by-design during SEO audits. The tool is useful for privacy engineers, web developers, and compliance teams who need auditable reports and repeatable scans across domains or subdomains.
Core value drivers include automation, reproducible results, and lightweight integration. Advanced users can perform batch scans, customize risk thresholds, and integrate with CI/CD or privacy platforms via API. The approach emphasizes accuracy, speed, and actionable insights for governance and optimization.

How to Use

  1. Provide the target URL and optional scope settings (include_subdomains, max_depth).
  2. Run the scan to render pages and collect cookies from headers and scripts.
  3. Review the generated cookie inventory and risk metrics in the results.
  4. Export the report as JSON or CSV if needed.
  5. Use the insights to adjust privacy banners and consent configurations.

Frequently Asked Questions

Find Quick Answers

What does the tool output?
The tool outputs a structured list of cookies with metadata (name, domain, path, expires, attributes) and summary counts, plus a per-site risk score. Values are redacted by default to protect sensitive data, with an option to export raw values in secure environments.
How is first-party vs third-party determined?
First-party cookies are those whose domain matches the target URL; third-party cookies originate from a different domain, typically loaded by external scripts or trackers found on the page.
Can it analyze dynamic cookies set by JavaScript?
Yes. The tool renders pages in a headless environment to execute JavaScript, capturing cookies set after dynamic actions in addition to those from response headers.
Can results be exported for use in reports?
Yes. Results can be exported as JSON or CSV to support governance, audits, and integration with other privacy platforms or dashboards.
