Free Cookie Scanner — Any URL in 30s
A cookie audit tool lists the cookies a public page sets and sorts them. This scan does not block cookies and does not decide compliance.
How Our Cookie Audit Tool Works
Our cookie audit tool uses advanced browser-based scanning technology to detect cookies exactly as your visitors experience them. Unlike basic cookie scanners that only check HTTP headers, our tool executes JavaScript, loads dynamic content, and captures cookies set by third-party scripts after page load -- giving you a complete picture of your site's cookie footprint.
What Makes Our Cookie Scanning Technology Different
Many free cookie scanning tools only perform a superficial scan -- checking the initial HTTP response headers for Set-Cookie directives. This misses a significant portion of cookies on modern websites, where JavaScript-based analytics platforms, advertising pixels, and consent management platforms set cookies dynamically after the page loads.
Our web cookie scanner takes a different approach. It uses a full headless browser environment that:
- Executes all JavaScript on the page, including deferred and async scripts
- Waits for dynamic content to load, capturing late-firing tracking pixels
- Detects cookies from embedded iframes and third-party domains
- Identifies localStorage and sessionStorage usage alongside traditional cookies
- Checks for fingerprinting scripts that track users without cookies
This browser-based approach ensures our cookie checker catches what simpler tools miss -- giving you confidence that your cookie audit is truly comprehensive.

Cookie Types Explained: What the Scanner Detects
Understanding what each cookie category means is essential for configuring your consent banner correctly. Here is what our cookie scanner looks for in each category:
Strictly Necessary Cookies
These cookies are essential for your website to function. They handle session management, authentication, shopping cart functionality, and security features. Under GDPR, CCPA, and PIPEDA, strictly necessary cookies do not require user consent because the website cannot operate without them. Examples include session IDs, CSRF tokens, and load balancer cookies.
Functional Cookies
Functional cookies remember user preferences like language selection, theme (dark/light mode), and region settings. They improve the user experience but are not strictly required for the site to work. Most privacy laws require consent before setting functional cookies, though PIPEDA allows implied consent for non-sensitive functional cookies when clear notice is provided.
Analytics Cookies
Analytics cookies track how visitors interact with your website — page views, scroll depth, click patterns, and session duration. Google Analytics (_ga, _gid), Hotjar, Mixpanel, and similar tools use these cookies. Under the EU GDPR they need opt-in consent before they load. In the UK, since 5 February 2026, cookies used only to collect statistics about that site can run without prior consent if people have a simple, free way to object. A tool that shares identifiers with an advertising network is outside that exception. Under CCPA, analytics cookies generally do not trigger the "Do Not Sell or Share" duty unless the data is sold or shared for cross-context advertising.
Marketing & Advertising Cookies
Marketing cookies track users across websites to build advertising profiles. These include Facebook Pixel (_fbp), Google Ads (IDE, _gcl_*), and programmatic advertising cookies. Marketing cookies always require explicit opt-in consent under GDPR and trigger the "Do Not Sell or Share" disclosure under CCPA. These are typically the highest-risk cookies on any website and should be blocked by default until consent is granted.
Why You Need a Website Cookie Scanner
If your website has any visitors from the EU, California, Canada, or the UK, you are subject to cookie consent laws. A website cookie scanner is not just a nice-to-have -- it is a fundamental compliance requirement. Here is why every website owner needs to perform regular cookie scans:
Legal Compliance Requirements
Under the GDPR, websites must obtain informed, specific consent before setting non-essential cookies. To provide informed consent, you need to know exactly which cookies your site uses -- their names, purposes, durations, and whether they share data with third parties. A cookie scan gives you this information.
The CCPA (California Consumer Privacy Act) requires businesses to disclose the categories of personal information they collect, including data gathered through cookies. If your cookie scanner reveals marketing or advertising cookies, you must provide a "Do Not Sell or Share My Personal Information" link on your website.
Canada's PIPEDA and Quebec's Law 25 impose similar requirements. Law 25 penalties can reach $25 million CAD or 4% of worldwide turnover. See the Canada cookie consent guide for federal and provincial rules. Regular cookie audits using a cookie scanning tool help you stay compliant as your website evolves and third-party scripts change.
Hidden Cookies You Do Not Know About
Most website owners are surprised by the results of their first cookie scan. Websites commonly have 20 to 50 or more cookies, yet only a handful are intentionally placed by the site owner. The rest come from:
- Analytics platforms like Google Analytics, Hotjar, or Mixpanel that set multiple tracking cookies
- Advertising networks including Google Ads, Facebook Pixel, and programmatic ad scripts
- Social media widgets such as share buttons, embedded posts, and comment systems
- Live chat tools like Intercom, Drift, or Zendesk that track visitor behavior
- CMS plugins and themes that include third-party scripts you may not be aware of
- CDN and hosting providers that sometimes set their own performance cookies
Accurate Cookie Consent Banners
Your cookie consent banner is only as good as the data behind it. If your banner lists four categories of cookies but your site actually sets cookies in categories you have not disclosed, your consent mechanism is technically non-compliant. Running a cookie audit ensures your banner accurately reflects reality. After scanning, you can use the results to build a properly configured cookie banner that matches your actual cookie usage.

Cookie Scanning Best Practices
Running a cookie scan is just the first step. Follow these best practices to maintain ongoing compliance:
1. Scan Before and After Every Website Change
Any change to your website can introduce new cookies. Adding a new analytics tool, installing a WordPress plugin, or embedding a video player can all result in additional cookies being set. Run a cookie scan before and after deployment to catch any new cookies.
2. Schedule Regular Quarterly Audits
Even without intentional changes, cookies on your website can change. Third-party services update their tracking scripts, and CMS platforms push updates that may include new tracking. Set a calendar reminder to run a comprehensive cookie audit at least every quarter.
3. Test Multiple Pages
Different pages on your website may set different cookies. Your checkout page might load payment processor scripts, your blog might embed social media widgets, and your contact page might load a third-party form builder.
4. Update Your Cookie Policy After Every Scan
Your cookie policy must accurately reflect the cookies your website actually uses. After each cookie scan, compare the results against your published cookie policy and update it. You can use our cookie policy template to get started.
5. Verify Your Consent Banner Blocks Cookies
This scan lists cookies a public page sets. It does not block them, and a scan does not prove a banner is holding scripts. To check a banner, open the site and confirm scripts you added have not run before a choice. The verification guide explains that check.
Cookie Scanner FAQ
Common questions about cookie scanning, cookie audits, and compliance
What is a cookie scanner?
A cookie audit tool lists the cookies a public page sets and sorts them into categories such as necessary, analytics, marketing, and functional. This scanner does that. It does not block cookies and it does not decide whether the site is compliant.
Is this cookie scanner really free?
Yes, our cookie scanner is 100% free with no hidden costs. You can run unlimited cookie scans without creating an account or providing any personal information.
What privacy laws does the cookie scanner check against?
The scan does not decide compliance with GDPR, CCPA, or PIPEDA. It lists cookies and can show notes. Whether a cookie needs consent depends on the law and the visitor.
Do I need a cookie banner if the scanner finds tracking cookies?
The scan does not answer that. A list of analytics or marketing cookies is a reason to read the rule for those visitors. The scanner does not block those cookies. You can start a free banner after you decide which scripts should wait for a choice.
What should I do after running a cookie scan?
Review the detected cookies, remove unnecessary ones, update your cookie policy, implement or update your cookie consent banner, and set a reminder to re-scan in 3 months. Read our GDPR cookie consent guide for detailed steps.
Does the cookie scanner work with any website platform?
Yes, our cookie scanner works with any publicly accessible website — WordPress, Shopify, Wix, Squarespace, custom-built sites, and any other web platform.
What is the difference between first-party and third-party cookies?
First-party cookies are set by your own domain and typically handle sessions, authentication, and user preferences. Third-party cookies are set by external services embedded on your site — like Google Analytics, Facebook Pixel, or advertising networks. Third-party cookies are more heavily regulated because they can track users across multiple websites.
How do I fix compliance issues found by the cookie scanner?
The scan does not find a compliance grade. If you want scripts you add to wait for a choice, start a banner. It cannot block cookies other code sets. Update the cookie policy so it lists what the scan found.
Is a cookie scan the same as a privacy audit?
A cookie scan is one component of a broader privacy audit. It focuses specifically on cookies and tracking technologies. A full privacy audit also covers data processing agreements, privacy policies, data retention practices, and security measures. However, a cookie scan is often the most actionable first step because it reveals concrete, fixable issues.
What to Do After Your Cookie Scan
A scan is an inventory. These five steps turn it into a consent setup that matches the cookies on your site.
- 1
Block non-essential cookies until opt-in
Analytics, marketing, and most functional cookies should not fire until a visitor accepts. Start a free cookie banner that holds those scripts until consent.
- 2
Match the banner to cookies the scanner found
Map each cookie to necessary, functional, analytics, or marketing. Your banner categories should match this inventory — not a generic list of cookies you hoped were there.
- 3
Update your cookie and privacy policy
List every cookie the scanner returned: name, provider, purpose, and expiry. Start from a cookie policy template and fill in what you actually use.
- 4
Wire Google tags to Consent Mode v2
If you use Google Analytics or Ads, send consent signals so tags wait for the visitor's choice. Follow the Google Tag Manager cookie consent guide.
- 5
Re-scan after shipping
A second scan lists cookies. It does not prove the banner blocked them. See how verification works.
