I build a better one https://teable.io/ and plan to open source it next week

There's also https://www.airsequel.com/

And

https://airforms.com/

I'll share my own project: https://www.myowndb.com/, running since 2006. I neglected the project for a couple of years but recently launched the new version. It's open source: https://gitlab.com/myowndb/myowndb

I enjoy the technical side, but I'm struggling to commercialise it so don't hesitate to give me your feedback here or on https://www.myowndb.com/contact.html which is of course powered by a myowndb public form :-)

heh, I'll throw my formial (https://github.com/nathanstitt/formial) project onto this thread. I probably need to update it a bit but it's been working well in production for 2+ years now.

Where were all these alternatives when I was looking for a WYSIWYG form builder?
