OpenMQTT review

Reviewed by iTechGuides Editors · Editorial team · Updated Nov 2026

OpenMQTT is a managed MQTT broker paired with a browser workspace for IoT developers, makers, and small teams working with connected devices. It brings device credentials, topic exploration, and a WebSocket client for publishing, subscribing, and debugging into the browser. Private workspaces use authentication and TLS, while live widgets and usage statistics provide views of device activity and topic performance. It suits solo users who want browser-based controls without setting up broker infrastructure, but its emphasis is narrower than a general-purpose device platform.

The product’s browser tools cover more than message inspection: users can create scheduled MQTT publishing actions and trigger scenarios through webhooks. Live widgets display real-time device data, and usage statistics cover device activity and topic performance. This combination can support prototyping and routine monitoring from a single workspace. The published plan names also indicate a distinction in message quality of service: Free includes QoS 0, while Premium includes QoS 0, 1, and 2, along with unlimited topics and premium clusters. Yearly Premium includes everything in monthly Premium and a 12-month price lock.

OpenMQTT is a reasonable fit for solo users or small teams who value a managed cloud broker and browser-based device workflows. The free tier offers MQTT Academy and QoS 0, while paid Premium adds the broader topic and QoS options. The published plans do not establish a broad broker feature set beyond the MQTT 5.0 cluster network and workspace tools, so teams evaluating more extensive broker requirements should compare alternatives. It is also a web-oriented product, with no desktop platform listed here.

OpenMQTT pros and cons

• Where it wins
  • Manage devices, credentials, and private workspaces in one browser workspace.
  • Explore topics and publish or subscribe with the browser MQTT client.
  • Use live widgets, scheduled publishing, and webhook-triggered scenarios.
• Where it doesn't
  • The Free plan is limited to QoS 0.
  • Unlimited topics and QoS 1 and 2 require Premium.
  • The product is focused on MQTT 5.0 and does not support other listed versions.
