PostMessage Inspector

Debug iframe communication without touching a single line of code.

PostMessage Inspector adds a dedicated Post Messages tab to Chrome DevTools, giving you instant, real-time visibility into every postMessage flowing between your page and its iframes - across all frames, all origins, all directions.

No setup. No build step. Just open DevTools and start inspecting.

WHY POSTMESSAGE INSPECTOR?

postMessage is the backbone of modern iframe communication - but it's notoriously hard to debug. Console logs get buried, events are easy to miss, and cross-origin frames make things even messier. PostMessage Inspector was built to fix that.
