Hello. Are you planning to provide SDK for free? It seems to me that some small payment wont prevent interested people from acquisition, but itll help to increase the budget of the platform.
As of now, the plan is to provide it for free and open source - this is an open source project. In our opinion, this would only add friction to the system and jeopardize adoption. The business model is based on other things that don't burden the work of developers if they want to use our tools.
