EMQX offers a generous Serverless tier with a free quota, making it accessible for small projects and testing.

How EMQX Compares to Competitors

Compared to AWS IoT Core, EMQX's Serverless tier offers a more explicit free quota structure, potentially simplifying cost prediction for lower usage. While other managed MQTT brokers like HiveMQ Cloud also offer free tiers, EMQX's Dedicated Flex at $234/month provides a competitive entry point for dedicated infrastructure with strong SLA and support, often at a lower initial cost than comparable enterprise-grade solutions.
