Usuaia is a platform for you publishers. We know how hard it is to finalize a product, evolve it and engage with your users, so we created Usuaia to help you with that.
We can't think of a better way to help than offering Usuaia for free! That's right, zero, null, nothing.... You can have the standard package for free always.
We'll release a PRO package in the future but a FREE plan will always be there.
And remember, if you have a feature in mind that you'd like to be implemented, please just drop a message in the Usuaia forums!
