About
EMQX Serverless is a managed MQTT broker for IoT messaging. It provisions a deployment in seconds and uses a shared, multi-tenant architecture with usage-based pricing for connected devices, session minutes, traffic, and rule actions.
The free offering includes 1 million session minutes per month, 1 GB of traffic per month, and 1 million rule actions per month. The pricing page also lists up to 1,000 connections, TLS/SSL encryption, basic monitoring and alerts, and 8/5 support on the Serverless plan.
- Shared, multi-tenant MQTT broker

Free Tier Value
This free tier is genuinely usable every month: it includes up to 1,000 connections plus recurring quotas for sessions, traffic, and rule actions, and the offer is perpetual rather than a short trial. The cheapest paid alternative starts at $234/month, so a free tier that covers the core broker experience but keeps usage capped and support/basic features only is worth about $25/month, or roughly 11% of the entry paid plan.
What's included in the free tier
- Up to 1,000 connections.
- Free monthly quota on sessions, traffic, and rule actions.
- TLS/SSL encryption.
- Basic monitoring and alerts.
- 8/5 support.
