iOS & iPadOS
MQTT Commander for iPhone & iPad
A professional MQTT client and debugger, native to iOS. Connect to any broker, inspect every payload, and find out exactly why a connection fails — from the device in your hand.
A real debugger, not a thin viewer
MQTT Commander brings desktop-grade MQTT debugging to iPhone and iPad: MQTT 3.1.1 and 5.0, QoS 0/1/2, TLS and mutual TLS, a topic tree built for thousands of topics, and a payload inspector with JSON, hex, Base64 and image preview.

iPhone & iPad — FAQ
What iOS version do I need?
iPhone or iPad running iOS 15 or later. The interface is native SwiftUI and adapts to both form factors.
Does it run on iPad?
Yes — it's a universal app with an iPad-optimized layout, so the topic tree, payload inspector and publish composer all use the larger screen.
Can I automate MQTT from Shortcuts?
Yes. Saved publish commands are exposed as App Intents, so you can trigger them from the Shortcuts app, Siri or the Action button.
Is it a subscription?
No — it's a one-time purchase ($2.99 at launch). No subscription, no in-app purchases, no ads.
