Vibe coding: Drag-drop form builder for webinars and workshops

Every creator wants to design forms for events and workshops. Google Forms is the only free option, but it seems limited in its usability. Paid options (JotForm, TypeForm) come with lock-ins. So I built a locally runnable form maker using Claude Code, free of registration and even the internet (except the form submission part, of course!) The complete tool is available for download through Gumroad; the link is given in the Substack article.

Prompt / skill content

Build a drag-and-drop form maker using these custom controls.
How do I share it so that participants can fill in their own data without the organizer having to fill it in?
How can participants upload it to a central location without seeing each other’s forms?
Build this under the constraints: It should be a single HTML page without the need to download any code from the internet. It should be secure to run in every browser.
