With the builder code maturing and reaching an almost usable state, now is a good time to get real people applying real designs and use cases. Would you like to gain early access to the builder and help with feedback? Please let me know in the comments section or email if you can provide any feedback at all. I can provide extended private hosting to allow you to launch a few apps and play around with the tool so that you can evaluate its features.
Note that the builder app is not optimized for mobile devices so a desktop/Laptop and a good internet connection is required.
Thanks and any feedback is very valuable at this point!
