Postmaster Extension

Postmaster is a devtools panel for logging postMessages, which can be useful for debugging cross-window communication, including messages sent from iframes and MessagePorts. It includes a feature rich toolbar, making it a powerful debugging tool:

FEATURES:

LOGGING: Postmaster logs all messages with their origin, destination, time received, timestamp offset, and payload. Clear your logs at any time.

SEARCH: Filter through any of your received messages by origin, destination, or even the data payload. Supports regex matching to empower complex use cases.

SORT: Toggle how inbound messages are displayed, based on their time of receival.

PRETTIFY: By default, Postmaster displays all message payloads as formatted JSON when applicable. For a more compact view, you can turn this off.

PAUSE/PLAY: For debugging in scenarios with high volumes of exchanged messages, Postmaster supports a pause/play functionality to temporarily control the influx of logged messages.
