have you ever considered the possibility of open-sourcing parts of the Bubble code? For example, although Firebase is not free software, they have open-sourced all of their clients/SDKs. That means people that use Firebase can contribute with PRs and make the development go faster.
That way Bubble would move faster and the team would be able to better decide what should be left for OS development and what’s better to be done by the team itself. You’d even be able to use something like BountySource to get people really interested in contributing. I’m sure you guys know the benefits of what I’m talking about.
