How to build a no-code form builder SaaS with visual drag-and-drop editors, embeddable iframes, and Resend API for instant email submission notifications.

No-Code Form Builders: Drag-and-Drop Editors with Resend Email Notifications

Every business needs contact forms but not every business has developers. FormForge lets anyone build and embed forms without writing code.


1. Visual Form Builder

Users drag input components (text, email, select, checkbox) onto a canvas and configure validation rules visually:

typescript
const FIELD_TYPES = [ { type: 'text', label: 'Short Text', icon: 'Type' }, { type: 'email', label: 'Email', icon: 'Mail', validation: /^[^@]+@[^@]+$/ }, { type: 'select', label: 'Dropdown', icon: 'ChevronDown', options: [] }, { type: 'textarea', label: 'Long Text', icon: 'AlignLeft' }, ];

2. Embeddable Iframe

Published forms generate an iframe embed code that works on any website. The iframe auto-resizes to match the form content height.


3. Resend Email Notifications

When a form is submitted, Resend API sends instant email notifications to the form owner with a formatted summary of all responses.


Summary

Visual builders + iframe embedding + instant email notifications create a form platform that replaces expensive alternatives like Typeform.
