Our verdict on Bevywise CrystalMQ
Bevywise CrystalMQ is an MQTT broker for messaging between MQTT-enabled devices, applications, and systems. It is aimed at IoT and industrial IoT deployments, with options for small projects through enterprise environments. Teams can deploy it themselves or use a managed cloud service. Its support for MQTT 3.1, 3.1.1, and 5, plus QoS 0, 1, and 2, covers a range of common MQTT messaging needs, including retained messages and shared subscriptions.
The self-hosted pricing page presents a free Developer tier and a $299 one-time Starter license. Developer includes a self-hosted broker, MQTT authentication, and access control lists, and allows up to 10 clients. Starter raises that limit to 100 and adds TLS, data storage, and a REST API. Advanced adds a rule engine, dashboards and widgets, and Sparkplug awareness; Enterprise adds clustering, gateway and sub-device support, reports, and multi-tenancy. The published details do not give prices for those higher tiers. Bevywise also documents a separate free shared cloud plan, so buyers should distinguish it from the self-hosted licenses.
CrystalMQ’s feature range reaches beyond message routing: authentication methods include username/password, custom authentication, and client certificates, while storage and integration options include SQLite, MySQL, MSSQL, PostgreSQL, MongoDB, Elasticsearch, Kafka, Redis, InfluxDB, Amazon Kinesis, and HTTP. This makes it a candidate for teams connecting a broker to data systems or adding dashboards and persistence. The 100-client Starter ceiling is a meaningful constraint for larger deployments, and the license model may not suit buyers seeking an open-source broker. Small teams looking for a pay-once self-hosted option should consider it; teams needing more than 100 clients on Starter should look elsewhere or assess higher tiers.
