satyarajanaidu/OpnForm ? reverse-engineered prompt

Build me a beautiful open source form builder where people can create forms without coding, preview them, and collect submissions in a simple dashboard.

I want the app to let users make forms with common field types like text, date, URL, file uploads, and whatever else is needed for a solid form builder. It should support embedding forms anywhere, sending email notifications, and basic integrations like Slack, webhooks, and Discord. Include form logic, customization, captcha protection, analytics, and a way to see submissions and form stats clearly.

Make it feel polished and modern, with a clean editor and a good form list page. If there are setup details or current best practices that matter, look up the latest docs online and follow them. Also make sure it works well for self hosting and local development, since I want this to be something people can run themselves.
