Pricing and Billing ​

EMQX Cloud offers a variety of flexible product plans and pricing options to support the deployment of fully managed MQTT services exclusively for you on the leading cloud providers, so you can easily scale up or down as your needs change, without any hidden costs or fees.

Serverless Plan ​

EMQX Cloud Serverless Plan is billed based on the actual usage of your deployment, including the number of session minutes and the amount of traffic generated by messages. Each user is given a certain amount of free credits at the beginning of each month, which will be used first before any charges are incurred. After this free quota (session minute or traffic) is used up, you will then be charged for any additional usage.

Billing Unit ​

Session Minute: One session minute stands for one connection to the deployment in the span of a minute, dnd any fraction of a minute is rounded up to one minute.

Session: Total number of clients that are currently connected simultaneously, including offline clients that have enabled Persistent sessions.

Traffic: Traffic (including free traffic) refers to all public network traffic that flows in and out of your deployment.

Billing Plan ​

Billing method ​

Session fee = sessions * connection span (measured per minute or part thereof) / 1,000,000 * 2 Traffic fee = Inbound and outbound traffic（byte）/ 1024 / 1024 / 1024 * 0.15

The bill is calculated based on the fees accumulated in the previous 24 hours, with collections taking place at 0:00 daily. You can go to the Billings page in EMQX cloud console to find the details.

Spend Limit ​

Spend Limit helps you control how much money your Serverless deployment spends each month, and you'll receive a reminder when you reach that limit. You can set the Spend Limit when you create your deployment, and you can change it later.

The spend limit can be an integer from 0 to 10000:

• If it is set to 0, the deployment will only consume the free quota, which is 1 million connection minutes and 1 GB of traffic per month. When the free quota is used up, the deployment will be stopped.
• If it is set to an integer between 1 and 10,000, an action should also be selected when the consumption of the deployment reaches the limit for the month, such as stopping the deployment or reminding and continuing to charge. If there is an overdue bill, regardless of the action you previously set, the deployment will be stopped.

Dedicated Plan ​

EMQX Cloud's Dedicated Plan is charged based on the selected product plan (Standard or Professional), instance specifications, and message transmission network traffic. There are no restrictions on the number of messages, API calls, or data integration usage. You can select the appropriate product plan based on your business needs, and be confident that the costs remain transparent and manageable even as your business expands.

Billing Unit ​

Session: Total number of clients that are currently connected simultaneously, including offline clients that have enabled Persistent sessions.

Base Fee: The base fee for the instance is calculated based on the hourly unit price corresponding to the selected product plan and instance specifications (maximum connection number, message TPS) at the time of deployment. In practical usage, this fee is only related to the duration of usage and will not be affected by changes in usage (connection number, message TPS).

Traffic Fee: Each instance specification includes a certain amount of free traffic, which is valid for the current month and will be automatically cleared at the end of the month if any remains. When device communication exceeds the gifted traffic, additional traffic fees will be charged. Here, traffic, including free traffic, measures all traffic flowing out of the deployment, including:

• Traffic over VPC Peering or PrivateLink is not measured.
• Traffic from messages received by the deployment, such as messages sent to the deployment from the clients, is not measured.
• If the NAT gateway is enabled, outgoing traffic from deployment will be measured.

Billing Method ​

For Dedicated Plan deployments, charges are calculated every hour based on usage for the previous hour, and charged from your account balance. The hourly charges are then accumulated into monthly charges, which you can view in detail on the Billing Overview page.

BYOC Plan ​

EMQX Cloud BYOC will deploy the EMQX service in your cloud platform account, and the associated costs include cloud platform resource fees and EMQX Cloud BYOC license fees.
