ConnectMQ review
A managed MQTT option for small deployments that need live topic monitoring.
Reviewed by iTechGuides Editors · Editorial team · Updated Nov 2026
ConnectMQ provides managed, private MQTT broker instances for teams connecting sensors, machines, vehicles, and applications. It is aimed at organizations that want connected-device messaging without installing and maintaining broker servers. MQTT 3.1.1 and MQTT 5 support, plus TCP, TLS, WebSocket, and secure WebSocket transports, give it a focused protocol and transport range. A web dashboard brings together live topic monitoring, rules, alerts, and an alert log; an ISA-95 workspace and 3D digital twin extend the product toward industrial IoT use cases.
The pricing is freemium, but its free allowance is finite: the Free plan provides 10,000 session minutes one time, up to 5 concurrent connections, and a 256 KB maximum message size, with no card required. Basic costs $39 per month and adds 1,000,000 session minutes each month, ACL access control, and email support. Scale is $199 per month, with 10,000,000 monthly session minutes, a 1 MB maximum message size, ACL, and email support. The published maximum is 100 connections, so teams should compare that ceiling and their session-minute needs against expected demand before choosing a paid tier.
Security controls include username/password client authentication and per-topic publish and subscribe access control, while TLS and secure WebSocket are supported transport options. The dashboard and alerting help teams observe topic activity and respond to configured conditions. ConnectMQ is a reasonable fit for small managed deployments seeking visibility and controls without self-hosting. It is less compelling for teams that need a larger connection ceiling, an integration ecosystem, or verified clustering capabilities; those requirements point toward evaluating another broker. It is cloud-deployed and web-based, with email support on the paid plans.
