Cookie banner symmetry check

Check a page

Not open yet. Real-site scanning is not switched on in our scanner yet, and the service that runs this checker is not deployed. We would rather tell you that than show you a made-up result, so this form is switched off and nothing you type here is sent anywhere. When it opens, you will be able to check one page, with no sign-up.

Check this banner

When this checker is open: the page address you type is sent to our Crawler Watch service, which asks Cloudflare Turnstile (a human check) to confirm you are a person, limits how often one network can use the checker, and hands the page to a scanner on our own hardware. By default the scan report and screenshots are deleted after 72 hours. The privacy page has the details. There is no sign-up and no tracking script on this page.

What it will do

It loads the page in a real browser three times, each in a fresh session: once choosing Accept, once choosing Reject, and once closing the banner without choosing. It counts the clicks each took, notes what the banner did when it was closed and after a reload, and takes screenshots.

What you will see

• Which consent platform the banner appears to be, and whether it was visible.
• Clicks to accept and clicks to reject, with the path the checker took.
• Whether closing the banner without choosing was followed by new observed third-party requests, cookies from third-party requests or consent grants.
• Whether the banner came back after the choice and a reload.
• The screenshots of every step.

This is evidence of interface behavior, not a legal determination. Every line is an observation: "Observed", "Not observed" or "Not determined".

What it cannot tell you

• It counts clicks. It does not yet measure button size, contrast or order on the page: that part is in development and is not in this check.
• One page, one visit, one place, one browser setting, on the date shown. Banners can differ by country, device and visit.
• An automated browser can misread a banner. If it could not operate the banner it says "couldn't operate banner" and does not guess. Check the screenshots.
• It does not say what any law or regulator requires.

It only checks sites you own or are authorized to test, and you confirm that before you submit. It identifies itself honestly and respects robots.txt: see our scanner's page.
