Built for daily MQTT debugging

Five focused workspaces keep publish, subscribe, automation, broker health, and logs in one window.

Publish with templates

Expand topic patterns, choose QoS and retain, validate JSON or hex payloads, and link subscriptions for side-by-side verification. 

PUB TEST/DEVICE/{A,B}/cmd
QoS 1 · retain off
{ "action": "reboot" }

Subscribe clearly

Tree or list views, live message bubbles, search, multi-select cleanup, and export to JSON or CSV.

Automate replies

Schedule publishes or react to incoming topics so soak tests and demos keep running without babysitting.
