Consent Auditor – Cookie Consent & GDPR Checker

Check if a website's cookie banner really works: detect cookies and trackers set before consent or after reject. GDPR & CCPA.

Does a website really respect the choices made in its cookie banner? Consent Auditor shows you, with evidence. Open the side panel, start a monitoring session and browse the site like any visitor — look around, reject everything, accept, change your preferences. Consent Auditor follows every choice you make and checks every cookie, storage write and tracker request against the consent that was in effect at that exact moment. What it finds • Analytics or advertising cookies set before you answered the banner (in opt-in regions such as the EU/UK) • Tracking that continues after you clicked "Reject all" or turned a category off • Cookies set by the server before consent, which a banner cannot block • Tracker requests that carry identifiers although consent was denied — while correctly ignoring Google Consent Mode's cookieless pings • Google Consent Mode, IAB TCF/GPP or US privacy signals that disagree with the banner • Cookies missing from the site's cookie declaration, and cookies filed as "necessary" that are known analytics or advertising cookies • Choices that are forgotten on the next page, cookies left behind after withdrawing consent, sites running two consent tools at once How it works • Detects the consent tool and reads its own cookie declaration and consent state • Knows the applicable regime (opt-in, opt-out, notice only) and region, and lets you choose when it cannot tell • Checks independently against the Open Cookie Database, so misclassified cookies stand out • A coverage checklist tells you which consent states you have tested and which are still missing • Every finding comes with evidence: the cookie or request, time, page, consent state at that instant, the script that wrote it • Exports a full report as JSON, a shareable self-contained HTML file, or a CSV cookie inventory Consent Auditor only observes. It never clicks the banner, never changes your consent and never changes your region. It is meant for privacy and compliance professionals, developers, agencies and site owners who want technical evidence — it does not give legal advice. Works with more than 20 widely used consent management platforms and with banners based on the IAB Transparency & Consent Framework. Sites with a home-grown banner are supported too: you mark the consent state yourself. Not affiliated with any consent management platform. Privacy: everything stays in your browser. No account, no tracking, no data sent anywhere.
