The verdict: can you vibe code Outgrow?
Build a subset with Next.js and Tailwind, but keep paying if you need their 1,000+ native CRM integrations.
Creating a personal clone of Outgrow requires tackling a robust multi-step form and quiz builder with live preview state, combined with a dynamic math formula evaluator for calculators. While AI coding agents handle frontend component scaffolding and CRUD database schemas efficiently, building a bulletproof secure expression parser for math formulas and handling edge cases in responsive iFrame embedding will demand careful debugging over a few focused weekends.
Estimated effort: 2-3 weeks part-time
What you can't replicate
- Pre-existing integrations with 1,000+ external martech tools and CRMs
- Extensive template library built over a decade
- SOC 2 compliance and enterprise trust

Build guide
01Project Scaffolding and Database Schema
Initialize the Next.js project with Tailwind CSS, Shadcn UI, and set up the Turso database client with Drizzle ORM.
Create a new Next.js App Router project configured with TypeScript, Tailwind CSS, and Lucide icons. Set up Drizzle ORM connected to a Turso SQLite database. Create schema tables for 'contents' (id, title, type, user_id, theme_config, created_at), 'questions' (id, content_id, title, type, options_json, order_index), and 'leads' (id, content_id, email, answers_json, score, created_at). Implement a basic layout wrapper with sidebar navigation and configure environment variables in .env.local.02Authentication and Dashboard
Configure better-auth for user accounts and build the main dashboard listing user-created content pieces.
Install and configure better-auth with email/password authentication using the Turso database adapter. Build an authentication layout with sign-in and sign-up pages. Create the main dashboard page at /dashboard that fetches and displays the authenticated user's content pieces in a grid, with a 'Create New Content' modal supporting selection of content type (Quiz, Calculator, Form).03WYSIWYG Builder Canvas
Build the interactive content editor allowing users to add, reorder, and configure questions and logic branches.
Build a content editor page at /builder/[id] with a sidebar for adding questions and a central canvas preview. Implement state management using React Context or Zustand to allow editing question titles, selecting question types (multiple choice, numerical input, dropdown), adding options with associated scores or formula weights, and reordering questions via up/down controls or drag indicators. Persist changes to the backend via debounced API calls.04Dynamic Formula and Calculation Engine
Implement a secure expression evaluator for numerical calculators and outcome scoring logic.
Build a calculation engine utility for numerical calculators and outcome quizzes. For calculators, allow users to define mathematical formulas referencing variable input IDs (e.g., input_1 * input_2 / 100) and safely evaluate them using a secure math parsing library without eval risks. For quizzes, implement score summing logic and outcome mapping rules (e.g., if score >= 10, display Outcome A).05Interactive Client Renderer and Lead Capture
Create the public-facing runner view where respondents step through questions, see real-time calculations, and submit leads.
Build a public rendering page at /c/[id] that loads a published content piece. Implement a multi-step wizard component that renders questions one by one or in a single column layout depending on configuration. Wire up live calculation updates for numerical inputs. Add a mandatory or optional lead capture gate step before displaying the final results screen, storing submissions into the 'leads' table and triggering webhook notifications if configured.06Analytics and Lead Management View
Build analytics dashboards to view lead submission metrics, conversion rates, and individual lead details.
Create a lead management and analytics page at /dashboard/[id]/analytics. Implement summary statistic cards showing total visits, total leads, and conversion rate percentage. Build a data table displaying captured lead emails, submitted scores, answers json breakdown, and export-to-CSV functionality.
