About

TCF Auditor is a professional-grade tool designed for AdTech experts, Publishers, and Compliance Officers to audit IAB TCF v2.2 & v2.3 implementations in real-time.

In the programmatic world, every millisecond counts. A slow CMP can lead to bidder timeouts and massive revenue leaks. TCF Auditor helps you identify these bottlenecks instantly.

Key Features:

⚡ Latency Tracking: Measure precise timing for __tcfapiLocator, Stub, and API responsiveness.

⚖️ Compliance Audit: Detect missing "Disclosed Vendors" (v2.3) and illegal "Legitimate Interest" on purposes 3, 4, 5, 6 (v2.2).

🔍 Structural Check: Verify Policy Versions, Service Specific settings, and TC String expiration.

💻 Dev-First: Clean, professional logs directly in your Chrome Console—no bloated UI, just the data you need.

Privacy-First: TCF Auditor does not collect any personal data. All processing is performed locally within your browser.
