Beacon

Capture and decode web analytics, tag-manager, and consent beacons in DevTools: inspect events, validate data, and debug tracking.

Beacon is a developer tool that lives in Chrome DevTools and shows you exactly what your website's tracking is doing. When a page sends an analytics, tag-manager, or consent request, Beacon captures it and decodes the raw payload into clean, readable fields — so you can verify what's being collected instead of squinting at query strings and encoded request bodies. It's built for the people who own measurement and tagging: analytics engineers, web developers, and QA teams who need to confirm that the right data fires at the right time. What you can do with Beacon - Capture and decode tracking requests live as they fire, with the raw shorthand translated into plain, structured key-value data. - Inspect both the request and the response for each call. - See firing order on a timeline with a waterfall view, so you can tell what loaded when. - Catch double-fires — the same event sent more than once in a short window. - Search and filter captured requests by field, value, or tool. - Compare two requests side by side to see exactly what changed between them. - Read your tag manager's data layer, rules, and loaded tags. - Get a one-click session summary of everything that fired on the page. - Switch between light and dark themes. What it works with Beacon understands the major analytics platforms, tag managers, consent-management tools, and the advertising and social tracking pixels that most sites rely on. It has especially deep support for major analytics platforms, decoding their event structures into readable detail. Privacy Beacon runs entirely inside your browser's DevTools. Captured data stays on your machine and is never sent to the developer or any third party. An optional Adobe Experience Platform connection is available for schema validation; it talks directly to Adobe's APIs using credentials you provide, and is entirely opt-in.
