I like creating projects so I find the no-code movement very valuable.
Abstra seems like a low-code to me. Maybe that is what you mean "hackable no-code"? (edit: you mention low-code in your landing page) If that's the case, and since the lingo in the no/low-code movement is already established, maybe it's better to use it so people have a better understanding of what they can do with your platform, faster.
Trying to create a project fast, I can quickly understand there is a learning curve required. At least steeper than other platforms. It would be very valuable if the first thing that happens when I log in for the first time is a walkthrough. Also, give some pre-made templates so people can modify those to their need. And by doing that they will learn the platform.
First impression is that I don't quickly understand if what I can create with abstra is websites, Saas, mobile apps, etc.
-All the best!
