Hello 
As we said time ago, Kodular is going to be FREE FOREVER. We won’t add any premium plan or make paid features on the Creator, as we want it accessible for everyone indepently from their income
But, as you might suppose, we need to pay our servers to keep running it
A great opportunity for helping us is supporting Kodular on Patreon:
Patreon is a platform where you can support projects by donating a montly amount which is dedicated to it
So, why not support Kodular there? You will get a badge on the community and you will be also part of this amazing project 
Thanks
