I just tried this no-code form builder 49forms.com

Thanks for sharing, Zeng. Good experiment! And seems quite easy to set up.

I tried it and it's good! ... super basic and easy. I think you @zeng could do yourself a favor by improving the homepage. Have a video demo of someone using the tool for the first time, testing vis first form (twice) and showing the reporting page. To show people visually how easy it is to use.
