Built in SwiftUI

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 why a connection fails, from the device in your hand.
A real debugger on a phone
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.
Native for iOS
Made for the platform
Keychain-backed
Broker credentials, certificates and private keys live in the iOS Keychain, never in a plain profile.
Siri Shortcuts & App Intents
Publish saved commands from Shortcuts or the Action button, and automate your smart home from anywhere on the device.
Dark mode & Dynamic Type
Adapts to your appearance and text-size settings, with full VoiceOver support.
Toolkit
Everything you need to work with MQTT
Broker profiles & templates
Save your brokers with ready-made templates for Mosquitto, Home Assistant, Zigbee2MQTT and AWS IoT. You get one profile free and more with Pro, and the app reconnects with backoff when the network changes.
MQTT 3.1.1 & 5.0
Full MQTT 5 properties, QoS 0/1/2, retained messages, Last Will, wildcard and shared subscriptions, over TCP, TLS, WebSocket or WSS.
Payload Inspector
Pretty-print and syntax-highlight JSON, diff two payloads, decode hex and Base64, preview images, and copy any value by JSONPath.
Topic tree & smart-home presets
Browse the whole broker or jump straight to homeassistant/# and zigbee2mqtt/#. Retained markers, regex filtering, and built to handle thousands of topics.
Safe publish composer
Draft-first publishing with QoS, a retain warning, explicit retained-delete confirmation, reusable templates and safe home-automation presets.
Message log & export
Filter traffic by topic, payload, direction, QoS or errors, then export to CSV or JSON, with secrets and raw payloads redacted.
iPhone & iPad FAQ
What iOS version do I need?
iPhone or iPad running iOS 17 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. The app is free to download, and Pro is a one-time $4.99 unlock you keep for good. No subscription, no ads.
