Jibble has a basic plan, which is free. And a paid subscription, called the power plan that starts from $10 per month that includes 5 Monthly Active Users (MAUs). Additional MAUs are charged at $2 per month.
The main difference between the two plans is that teams on the basic plan have access to only the standard power-ups, and the teams on the power plan have access to ALL the premium power-ups.
