Pricing
We offer a free plan with basic support for testing and development. When you're ready to move to production or exceed 200 monthly active users (MAUs) and/or 1 million transactions/Functions executions, you need to upgrade to a paid account.
MAUs are unique users (with unique user IDs) that connect to PubNub at least once in a calendar month and send an API call. If you'd rather pay for transactions, you may consider transaction-based pricing.
