About Headless Form Builder
CustomJS provides the missing headless infrastructure for your AI-generated projects. Your AI designs the UI, and we provide the instant API endpoint to collect submissions without any backend setup. It is the perfect bridge for AI-powered forms or custom integrations—just send your JSON data to be stored and trigger automated email notifications or workflows in Make and n8n. Beyond forms, you can turn any email into a webhook, generate PDFs from HTML templates, and host static pages in seconds.
