Thanks for the interest! The questions you are asking are very valid. Let me address them one by one:
1. We are evaluating an open source strategy, but currently don't have plans to open source it. There are couple ways we're addressing this. First, in an event of a closure of the platform we commit to open sourcing it, just like Parse did. Second, which is a more immediate one, is that we will be adding features that make 8base fit well into developer workflows as a tool rather than a platform. That way developers don't have to commit to building on 8base right away and can use it as an integration layer that accelerates access to business data and workflows. By focusing on enterprise use cases we believe we can achieve a good value proposition without forcing people to build entire application on 8base. Also, as serverless architecture becomes more pervasive porting business logic comprised of cloud functions should become easier than before (this is a somewhat weaker point).
2. We're still working on the pricing and gathering feedback. If you don't mind, could you share which aspects of pricing concern you specifically? Indeed a SaaS, especially one in the enterprise space, is definitely our target. As a matter of fact, we already have an enterprise SaaS built on 8base that's launching in a few months.
