What does OpnForm do?
OpnForm is an open-source form builder that lets anyone create functional web forms without coding knowledge. You can build contact forms, surveys, registration forms, and more with a drag-and-drop interface. The platform supports over 10 input types, file uploads up to 5MB, and includes templates for common use cases like client feedback, event registration, and donation collection. What makes OpnForm stand out is its AI-powered form generation feature, which can create a complete form from a simple text description in seconds. The platform also offers conditional logic, multi-page forms, custom thank-you pages, and extensive customization options for colors and branding. Unlike many form builders, OpnForm offers a genuinely generous free plan with unlimited forms and submissions. Small business owners, bloggers, and community organizers will find OpnForm particularly useful for quickly setting up professional-looking forms for customer feedback, event registrations, or lead capture without worrying about submission limits or complex setup processes.
