MQTT Connect is a secure, private client for managing MQTT brokers and clients — built for the people who actually run MQTT infrastructure, not a toy demo app.
There's no account, no cloud backend, and nothing phoning home. Every broker profile, client, credential and certificate you add is encrypted and stored only on your device. MQTT Connect only ever talks to the brokers your clients are configured to connect to.
SECURE BY DESIGN
• Broker profiles, clients, credentials and certificates encrypted at rest in your device's keychain
• Face ID / biometric lock, auto-lock, and payload hiding in the app switcher
• Full mutual TLS (mTLS): import CA certificates, client certificates and private keys from PEM, paste them directly, or unlock a .p12 bundle in one step
• Zero analytics, zero crash reporters, zero telemetry — offline-first by default
BUILT FOR REAL MQTT WORK
• Save a broker's host, port and transport once, then create as many clients as you need — each with its own ID, auth and certificates
• Full support for MQTT 3.1.1 and 5.0 over TCP, TLS, WS and WSS
• A live message feed for every client — expand any message for QoS, retain flag and payload, and re-send or edit-and-send instantly
• A publish composer with JSON, text and Base64 payloads, topic autocomplete from your history, and pinned snippets for frequent sends
• Smart topic suggestions drawn from what you've already subscribed to or published, per client
YOUR DATA, YOUR DEVICE
Export your client configuration without secrets to move between devices, or erase everything permanently with one tap. Because MQTT Connect holds no copy of your data, that erase is final — and that's the point.
Whether you're debugging a broker in production, monitoring sensors on a home network, or testing firmware over MQTT, MQTT Connect keeps your connections fast, your credentials private, and your device the only place any of it lives.
