TagScanner

TagScanner is a free Chrome extension for anyone working with Adobe Tags (Launch). Open it on any live site running Adobe Tags and get an instant, complete view of the property — rules, data elements, extensions, dependencies, and custom code — with no API credentials, no backend access, and no admin rights required. It reads directly from the _satellite container object that Adobe Tags injects into every page. That object is always there. TagScanner just surfaces everything inside it. ━━━━━━━━━━━━━━━━━━━━━ WHAT YOU CAN DO Audit — Browse every rule with its events, conditions, actions, and custom code. Sortable, searchable, paginated. No more opening rules one by one in the Launch UI. Analyse — See full data element usage tracking: which rules reference each DE, which extensions use them, and DE-to-DE dependency chains. Deep Scan detects ghost dependencies — data elements referenced in custom code that don't exist in the compiled library. Visualise — Flow Diagram generates an interactive visual map of your entire property — data elements, rules, extensions, and the connections between them. Always reflects the current published library. Search — Global Code Search runs full-text search across every rule, data element, and extension including all custom code blocks, with line-level match highlighting. Export — One-click .xlsx export of every rule, data element, and extension including custom code. The export Launch itself can't give you. Debug — Environment Override redirects the live Tags library to dev or staging at the network level. No proxy tools. No test pages. No page changes required. ━━━━━━━━━━━━━━━━━━━━━ AI-POWERED FEATURES (Preview / Beta) AI Property Health Scan — A–F health score for your entire property with an executive summary, category scores, critical issues, and ranked recommendations. A manual audit that takes hours: this does it in under a minute. Custom Code Explanation — Plain-English breakdown of any custom code block: what it does, what data it reads, what it returns, risks, and ready-to-run debug commands. Ask AI — Natural language questions about your live property. "Which rules fire on page load?" "What data elements use the data layer?" Answered instantly with conversation persistence. Note: AI features are available on a best-effort basis. Core features are fully available with no restrictions. ━━━━━━━━━━━━━━━━━━━━━ WHO IT'S FOR Tag managers, analytics engineers, MarTech consultants, and implementation architects who audit, document, or optimise Adobe Tags properties — and want to spend less time in the Launch UI and more time on the actual work. ━━━━━━━━━━━━━━━━━━━━━ FREE. No sign-in required for core features. Google OAuth required for AI features only. For feedback: tagscannerfeedback@gmail.com
