HiveMQ

HiveMQ is an enterprise MQTT broker and IoT connectivity platform that provides reliable, scalable bidirectional messaging between connected devices and back-end systems using the MQTT protocol. It supports MQTT 3, MQTT 5, MQTT over WebSocket, clustering, multi-cloud deployments, and an extensible enterprise extension framework for security, data routing, and stream processing through HiveMQ Data Hub. HiveMQ exposes a REST API (OpenAPI 3.0) for broker administration, client management, backups, trace recordings, and Data Hub policy management.

HiveMQ publishes 4 APIs on the APIs.io network, including MQTT over WebSocket, Data Hub API, Management API, and 1 more. Tagged areas include MQTT, IoT, Messaging, Message Broker, and Pub-Sub.

The HiveMQ catalog on APIs.io includes 1 event-driven AsyncAPI specification and 1 Spectral governance ruleset.

HiveMQ’s developer surface includes authentication, documentation, pricing, signup flow, GitHub presence, engineering blog, support, and 25 more developer resources.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/hivemq: open an issue to ask a question, or submit a pull request to add artifacts.
