# How to Vibe Code Your Own Supademo (and Stop Paying for It) > AI-powered interactive product demo and enablement platform - Site: https://supademo.com - Category: Sales & Product Marketing Enablement - Verdict: **Serious undertaking** (45/100 vibecodeable) - Estimated effort: 3-5 weeks of focused part-time work ## Verdict Build a personal subset focusing on screenshot-based interactive walkthroughs and embedding hubs; the full HTML cloning engine and AI voice pipeline require months of intricate engineering. Replicating Supademo's core utility for personal use involves constructing a multi-part system: a Chrome extension to record screen actions, a rich-media player for interactive playback, and an embedding widget. While a CRUD dashboard and screenshot player can be vibecoded swiftly, the heavy engineering hurdles include safely serializing live HTML/CSS structures without breaking stylesheets, managing complex branching state machines, and orchestrating speech synthesis pipelines. Paying for the product is rational if you need production-ready reliability, but building a personal subset is a rewarding multi-week challenge. ### What you can't replicate - Enterprise CRM integrations with Salesforce and HubSpot - Extensive team permissions, SSO, and compliance audit logs - The massive PLG user base and pre-built template ecosystem ## What it does Capture software workflows and transform them into self-paced interactive walkthroughs, sandbox environments, and AI-driven voice/text guides. ### Core features - Workspace and user management dashboard - Chrome extension for event and screenshot capture - Interactive demo editor with hotspots, blur, and chapters - Shareable player view with responsive layout and tracking links - In-App Demo Hub widget embeddable via script tag - AI text personalization and translation pipeline - Advanced HTML/CSS frontend cloning and sanitization engine ## The business ### Pricing - Starter: $0 — Free forever for individuals - Scale: $38/mo — Billed per creator - Growth: $350/mo — Bundled for 5 creators Founded 2022. Team size: 10-15. ## The hard parts - Serializing DOM trees, sanitizing active scripts, and handling relative assets for Guided HTML clones - Building a reliable Chrome extension that hooks into DOM clicks and inputs without breaking target apps - Managing multi-step interactive state, conditional branching, and dynamic variable replacement in the player - Synthesizing and synchronizing multi-language AI voiceovers with slide navigation timelines ## How to vibe code Supademo ### Prerequisites - Node.js (free): Required runtime for local development and package management. - GitHub (free): Source code repository and CI/CD deployment connection. ### Recommended AI tools - Claude Code: Best-in-class coding agent for scaffolding multi-file architectures, building the Chrome extension, and debugging React state loops. - Cursor: Ideal AI-native IDE for fine-tuning the interactive demo player UI and styling hotspot elements. ### Stack - Frontend: Next.js with Tailwind CSS and shadcn/ui - Backend: Next.js App Router API Routes - Database: Neon (Serverless Postgres) - Auth: better-auth - Payments: None (Personal use clone) - Other: Cloudflare R2 for screenshot and media storage, OpenAI API for AI text personalization, ElevenLabs API for optional AI voiceovers, PostHog for analytics and session replay ### Hosting - Vercel (Hosting the Next.js creator dashboard, player web app, and embedding scripts): $0-20/mo - Cloudflare (R2 Object storage for captured screenshots and media assets with zero egress fees): $0-5/mo ### Build guide 1. **Project Scaffolding and Database Schema** — Initialize the Next.js project with Tailwind CSS, shadcn/ui, Neon Postgres, and better-auth. ``` Scramble up a new Next.js project using App Router, TypeScript, Tailwind CSS, and configure shadcn/ui primitives. Set up better-auth with email/password authentication connected to a Neon Postgres database via Prisma or Drizzle ORM. Create database schemas for Workspaces, Demos (containing title, description, settings), Steps (containing step order, screenshot URL, hotspot coordinates, tooltips, and actions), and Views (for analytics tracking). Verify the schema applies cleanly and implement a protected creator dashboard route that lists user demos. ``` 2. **Chrome Extension for Capture & Screenshot** — Build a Manifest V3 Chrome extension that captures clicks, inputs, and page screenshots. ``` Create a Chrome extension using Manifest V3 that includes a background service worker and a content script. The content script must listen for mouse clicks and input changes across web pages, capturing bounding client rects, element tags, text content, and taking viewport screenshots via chrome.tabs.captureVisibleTab. Build a popup UI in the extension that lets the user stop recording and upload the collected step payload to our Next.js backend API endpoint (/api/demos/import). Handle authentication token passing between the web app and the extension. ``` 3. **Interactive Demo Editor & Step Management** — Build an intuitive editor interface to modify steps, add hotspots, adjust tooltips, and reorder content. ``` Build a robust interactive demo editor page in the Next.js dashboard at /dashboard/demos/[id]. The UI should display a filmstrip of captured step thumbnails on the left, a central canvas showing the active step screenshot with drag-and-drop hotspot positioning overlays (pointer, callout, area), and a right-hand properties panel to edit tooltip titles, descriptions, and CTA buttons. Implement drag-and-drop reordering for steps using @dnd-kit and connect state changes to autosave API routes with optimistic UI updates. ``` 4. **Responsive Player & Embedding Widget** — Develop the public-facing interactive demo player and a lightweight JavaScript snippet for embedding. ``` Create a public responsive demo player route at /view/[id] that renders steps sequentially with smooth pan/zoom transitions, animated click hotspots, typewriter text effects, and a bottom navigation control bar with chapters and lead capture forms. Additionally, build a standalone embed script (embed.js) that websites can include via a script tag to render an in-app Demo Hub widget or modal overlay triggering any demo from the user's workspace. ``` 5. **AI Personalization & Voiceover Integration** — Integrate OpenAI and ElevenLabs APIs to automatically generate text enhancements and voice narration. ``` Implement an AI enhancement suite in the demo editor using the Vercel AI SDK. Add an 'AI Generate Text' button that calls OpenAI to rewrite step descriptions into punchy, benefit-driven copy based on surrounding page context. Add a 'Generate Voiceover' action that sends step text descriptions to the ElevenLabs API, stores resulting audio files in Cloudflare R2, and syncs audio duration with step display timelines in the player. ``` 6. **Analytics & Polish** — Add tracking metrics, drop-off visualization, and production error monitoring. ``` Implement view tracking and analytics collection in the demo player: record unique viewers, completion rates, drop-off step percentages, and average session duration into the database. Build an analytics tab in the creator dashboard displaying visual charts (using recharts) for these metrics. Integrate Sentry for error tracking and PostHog for product telemetry. ``` ### Cost vs paying **Starting costs (one-time):** - Domain name (optional): $12 one-time - ElevenLabs / OpenAI developer starting credits: $10 one-time - Total: ~$22 one-time **Ongoing costs (monthly):** - Vercel Hobby/Pro hosting: $0-20/mo - Neon database & Cloudflare R2: $0/mo - AI API usage (OpenAI & ElevenLabs): ~$5/mo - Total: ~$5-25/mo - Paying for the SaaS instead: $38/mo (Scale tier) - Build time: 40-60 hours - AI tool credits: $20 (Claude Pro) - Break-even: 1-2 months if replacing paid tier ## Sources - [Supademo Official Website](https://supademo.com) - [Supademo In-App Demo Hub Feature](https://supademo.com/features/in-app-product-tour) - [Supademo Pricing Page](https://supademo.com/pricing)
