Fluxframe WebSocket Inspector

Fluxframe helps developers inspect live WebSocket traffic from web apps. Save multiple secure WebSocket endpoints, start capture on the active tab, and review matching connections in one stream. Fluxframe stitches NATS protocol frames into readable messages, distinguishes sent and received traffic, and shows connection activity. Search and filter the stream, inspect text and JSON payloads, copy messages, or export captures as JSON. Captures are stored locally in your browser profile. A Fluxframe account is required to use the extension. Fluxframe does not open WebSocket connections itself.
