I have a product that I plan to release soonishly. I am planning on doing a free-for-public, pay-for-private pricing model. For the latter, the choice is essentially between Github's model and Bitbucket's model. Github allows unlimited private collaborators but charges by the project. Bitbucket allows unlimited private projects but charges by the collaborator.
My question is: have any of you decided between these pricing models for your product? If so, how did you decide? Also, any related resources would be appreciated. Thanks!
