Tag Leak review
Audits consent behavior, tracking, and headers across multiple website pages.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Tag Leak scans websites in a real browser to identify cookies, tracking tags, browser storage writes, and third-party network requests before and after consent. It also checks consent banners, Google Consent Mode v2, IAB TCF v2.3 signals, and six security response headers. Founders, developers, marketing and legal teams, and agencies can use its multi-page audits to investigate where tracking occurs and how it responds to consent choices. The product is cloud-based and offered for web use.
The plans scale from an initial compliance check to ongoing audits. Free costs $0 per month and includes a compliance score, access to 50,000+ known trackers, and a partial report. Starter costs $19 per month and adds unlimited scans, full and security-header reports, Consent Mode v2 analysis, audits of up to 25 pages, and three monitored sites with weekly alerts. Pro costs $49 per month; it raises the audit scope to 100 pages and monitoring to 20 sites with daily alerts, and adds geo-scanning, white-label PDF reports, an AI Remediation Document, and a cookie policy generator. Choose based on audit depth and monitoring needs rather than treating the free tier as a full reporting option.
Its focus is the connection between consent and actual site behavior: audits can score against six privacy regulations, surface page-level findings, and produce PDF remediation documents and cookie policies. Scheduled rescans and email alerts support repeat checks on paid plans. Tag Leak lists Usercentrics, OneTrust, Cookiebot, Didomi, Quantcast, and Sourcepoint as integrations. Teams seeking detailed consent and tag-leak audits across multiple pages may find this scope useful; those needing a tool centered on a different privacy workflow should compare alternatives. Email is the listed support channel.
