TagGovernor runs as a persistent side panel — capturing, matching, and validating network requests against a configurable vendor library as you browse.
📡
Live Tab
Real-time network event feed for the active tab. Each row shows the request method, URL, matched vendor, and PASS / FAIL / WARN / EXCLUDED status. Click any row to expand the full URL, matched rule results with actual vs. expected values, query parameters, and POST body.

Vendors Tab
50+ built-in vendor definitions covering analytics, advertising, and data platforms. Create custom vendors or override built-ins. Organize with color-coded Labels. Group by Category or Label. Import and export with conflict resolution — overwrite, add as copy, or skip.
