# How to Vibe Code Your Own Cognito Forms (and Stop Paying for It)

> Free Online Form Builder With Workflow Automation

- Site: https://cognitoforms.com
- Category: Form Builder & Workflow Automation
- Platforms: Web app
- Verdict: **Solid side project** (62/100 vibecodeable)
- Estimated effort: 4-6 weeks of dedicated coding and debugging

## Verdict

You can build a functional personal clone of the form builder and approval engine, but writing a robust sandboxed formula parser and state machine will test your patience.

Cloning Cognito Forms for personal utility is a substantial undertaking because it requires orchestrating multiple complex subsystems: a drag-and-drop form canvas, a secure expression interpreter for calculations, a workflow state machine, and document rendering. While AI coding agents can scaffold the Next.js frontend and PostgreSQL schema rapidly, debugging subtle state synchronization issues in multi-step form submissions and conditional logic evaluation will require rigorous manual testing and iteration.

### What you can't replicate

- Official HIPAA and PCI-DSS Level 1 audit certifications
- Years of production hardening on edge-case expression evaluation bugs
- Enterprise trust and direct integrations with compliance ecosystems

## What it does

Advanced online form builder and workflow automation SaaS platform for capturing data, electronic signatures, secure payments, custom document generation, and multi-step approval workflows.

### Core features

- Drag-and-drop form builder with multi-page support
- Sandboxed expression language engine for real-time calculations and conditional logic
- Repeating sections and sub-tables
- Workflow state machine with role-based routing and task assignments
- Document generation (custom Word/PDF outputs)
- Secure payment processing integration (Stripe/Square/PayPal)
- Electronic signature capture
- Client portal with secure magic-link guest access
- Audit logging and folder-level permissions

- Ensuring strict encryption and data isolation boundaries for HIPAA compliance

## How to vibe code Cognito Forms

### Prerequisites

- Node.js (Free): Required runtime for building and running the Next.js full-stack application.
- GitHub (Free): Version control and repository hosting for your codebase.
- Supabase Account (Free): Managed PostgreSQL database and authentication provider for relational data and user sessions.

### Recommended AI tools

- Claude Code: Best-in-class terminal agent for scaffolding complex full-stack schemas, parsers, and multi-file Next.js components.
- Cursor: Ideal AI-native code editor for reviewing visual diffs and refining the drag-and-drop form builder interface.

### Stack

- Frontend: Next.js with Tailwind CSS and shadcn/ui
- Backend: Next.js Server Actions and API Routes
- Database: Supabase (PostgreSQL with Row Level Security)
- Auth: better-auth
- Payments: Stripe API
- Other: Zod for schema validation, mathjs or custom parser for expression evaluations

### Hosting

- Vercel (Hosting the Next.js frontend and serverless backend functions.): $0/mo (Hobby Tier)
- Supabase (PostgreSQL database storage and user authentication state.): $0/mo (Free Tier)

### Build guide

1. **Project Scaffolding & Database Schema** — Initialize the Next.js project with Tailwind CSS, configure Supabase PostgreSQL tables for users, organizations, forms, form fields, entries, and workflow states, and establish database migrations.

```
Scaffold a new Next.js 16 project using TypeScript and Tailwind CSS. Set up Supabase client connections and create Prisma or Drizzle schema definitions for organizations, forms (storing JSON field configurations), form entries, workflow definitions, and workflow step logs. Implement robust foreign key relations and indexes for fast entry lookups. Ensure all TypeScript types are fully generated and verify the build passes cleanly.
```

2. **Authentication & Organization Setup** — Integrate better-auth for secure user registration, email/password login, and multi-tenant organization creation and member management.

```
Integrate better-auth into the Next.js application supporting email/password login, session management, and organization switching. Build out protected API routes and frontend layout wrappers that enforce organization membership and basic role-based access control (Admin, User, Guest). Create account settings pages for updating user profiles and organization preferences.
```

3. **Visual Form Builder Canvas** — Build a responsive drag-and-drop form builder interface allowing users to add, reorder, and configure diverse field types (text, number, dropdown, file upload, repeating sections).

```
Build a visual form builder page in Next.js featuring a sidebar of available field types (text, choice, date, file upload, repeating section) and a central canvas where users can drag or click to add and reorder fields. Implement a field property editor panel on the right side that updates field settings (label, validation rules, required status, conditional visibility) in real time and saves the form configuration JSON to the database.
```

4. **Expression Language & Conditional Logic Engine** — Implement a secure calculation and conditional logic parser to evaluate field visibility rules and real-time mathematical expressions.

```
Develop a secure expression evaluation service in TypeScript that parses custom calculation formulas and conditional logic rules defined on form fields. The engine must safely evaluate arithmetic operations, string manipulations, and field value lookups across form submissions without executing unsafe code or arbitrary code injections. Integrate this engine into the live form renderer so fields dynamically show, hide, or recalculate values as users type.
```

5. **Workflow State Machine & Approvals** — Implement a status-based workflow engine allowing forms to transition through configurable approval steps with automated role-based task assignments.

```
Create a workflow automation module that allows form administrators to define custom statuses (e.g., Submitted, Under Review, Approved, Rejected) and assign role-based permissions for executing actions on entries. Build an in-app task management dashboard where users can view pending submissions assigned to their role or user ID, trigger status changes, and record audit trail history logs.
```

6. **Client Portal & Payment Integration** — Build token-authenticated guest client portals for external stakeholders and integrate Stripe for secure payment collection during form submission.

```
Build a secure client portal accessible via magic links or token authentication where external guests can view their submission history and track workflow progress. Additionally, integrate Stripe Checkout into the form submission flow so forms containing payment fields securely process transactions via Stripe webhooks before saving entries and triggering workflow states.
```
