Manage Realtime Messages usage
What you are charged for
You are charged for the number of messages going through Supabase Realtime throughout the billing cycle. Includes database changes, Broadcast and Presence.
Database changes Each database change counts as one message per client that listens to the event. For example, if a database change occurs and 5 clients listen to that database event, it counts as 5 messages.
Broadcast Each broadcast message counts as one message sent plus one message per subscribed client that receives it. For example, if you broadcast a message and 4 clients listen to it, it counts as 5 messages—1 sent and 4 received.
How charges are calculated
Realtime Messages are billed using Package pricing, with each package representing 1 million messages. If your usage falls between two packages, you are billed for the next whole package.
Example
For simplicity, let's assume a package size of 1,000,000 and a charge of $2.50 per package without quota.
