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

> Live & Automated Webinar Software That Converts

- Category: SaaS / Marketing & Webinars
- Verdict: **Serious undertaking** (38/100 vibecodeable)
- Estimated effort: 6-8 weeks of part-time development

## Verdict

Build a personal subset with prebuilt video APIs or keep paying, because scaling a custom multi-presenter WebRTC SFU cluster alongside marketing automation is a massive engineering undertaking.

Replicating WebinarJam's core loop—registration, email reminders, live video, chat, and active offers—demands substantial plumbing. While building a static registration page and simple chat with Next.js is straightforward, the live video broadcasting layer (handling multiple presenters streaming to thousands of concurrent viewers via WebRTC and SFU routing) will break a solo developer's workflow. You would need to offload the heavy media lifting to a managed video infrastructure provider like LiveKit Cloud or Daily, but wiring real-time offer synchronisation, failover room switching, and reliable email scheduling still requires weeks of rigorous backend engineering and debugging.

### What you can't replicate

- Proven enterprise-grade multi-region WebRTC infrastructure capable of handling thousands of concurrent viewers without desync
- Built-in user base and trust forged over a decade of high-stakes live product launches

## What it does

## The hard parts

- Scaling WebRTC SFU media architecture to support low-latency multi-presenter video and thousands of concurrent viewers
- Implementing instant stream failover and backup room switching ('Panic Button') without dropping active viewers
- Synchronizing real-time chat, polls, and timed buy buttons across thousands of client connections with varying latency
- Reliable transactional email and SMS dispatch scheduling for pre-webinar reminder sequences

## How to vibe code WebinarJam

### Prerequisites

- Node.js (free): Runtime environment for building and executing the full-stack web application.
- GitHub (free): Source control and automated deployment pipelines.

### Recommended AI tools

- Claude Code: Handles complex multi-file scaffolding, database schemas, and API integrations across the stack.
- Cursor: Provides an AI-native editor interface for refining UI components, registration pages, and real-time chat hooks.

### Stack

- Frontend: Next.js
- Backend: Next.js API Routes / Server Actions
- Database: Neon
- Auth: better-auth
- Payments: Stripe
- Other: LiveKit, Resend, Tailwind CSS, Vercel AI SDK

### Hosting

- Vercel (Hosting the Next.js frontend, API endpoints, and serverless functions.): $0-20/mo
- Neon (Serverless Postgres database storing registrants, webinar metadata, chat logs, and offers.): $0/mo

### Build guide

1. **Project Scaffolding & Database Schema** — Initialize a Next.js project with Tailwind CSS, configure better-auth for host accounts, and establish the Neon Postgres database schema for webinars, registrants, chat messages, and offers.

```
Initialize a Next.js project using App Router, TypeScript, and Tailwind CSS. Set up better-auth with email/password authentication for webinar hosts. Connect the app to a Neon Postgres database using Drizzle ORM or Prisma. Create database tables for 'Webinars' (id, title, description, scheduledAt, hostId, status, duration), 'Registrants' (id, webinarId, email, name, registeredAt), 'ChatMessages' (id, webinarId, senderName, message, timestamp), 'Polls' (id, webinarId, question, options, active), and 'Offers' (id, webinarId, title, price, buttonText, checkoutUrl, active). Ensure all foreign keys and indexes are correctly configured for high-frequency chat reads.
```

2. **Registration Page Builder & Funnel** — Build a customizable webinar registration page generator and public landing view that captures leads into the database.

```
Create a drag-and-drop or customizable registration page builder in Next.js where hosts can configure a webinar title, description, banner image, and speaker details. Generate a public registration route (/w/[webinarId]) featuring an email and name input form. When a user registers, save their record to the 'Registrants' table, trigger a confirmation email via Resend with a unique join link, and redirect them to a confirmation/thank-you page with calendar add links (ICS).
```

3. **Email & SMS Reminder Engine** — Implement background jobs or cron routines to dispatch reminder notifications at set intervals before the webinar starts.

```
Implement an automated reminder scheduling system using Vercel Cron or Inngest. Create cron jobs that check for upcoming webinars starting in 24 hours, 1 hour, and 15 minutes. Query the 'Registrants' table for each active webinar and dispatch custom HTML reminder emails containing personalized secure join tokens via Resend. Include UI controls in the webinar dashboard for hosts to view email delivery logs and subscriber stats.
```

4. **Live Video Broadcasting Integration** — Embed a WebRTC video room provider (LiveKit) to handle multi-presenter streaming and viewer broadcast distribution.

```
Integrate LiveKit Cloud SDK into the application to power the live webinar broadcasting room. Create two distinct room views: a 'Presenter Room' where up to 6 hosts can publish camera/microphone streams and share their screen, and an 'Attendee Room' configured for large-scale subscriber viewing with low-latency playback. Handle token generation securely via backend API routes so only authenticated hosts can broadcast while registered attendees join with viewer permissions.
```

5. **Real-Time Chat, Polls & Active Offers** — Build real-time interactive subsystems for audience chat, interactive polling, and timed active offer buy buttons.

```
Build a real-time engagement sidebar for the webinar room using WebSockets or Server-Sent Events (SSE). Implement live audience chat with moderation controls (delete message, ban user), interactive live polling where hosts can launch questions and render live bar charts of responses, and a timed 'Active Offer' component. The offer component should allow hosts to trigger a buy button with a countdown timer directly inside the attendee video room, redirecting users to a mock Stripe checkout or external URL when clicked.
```

6. **Analytics Dashboard & Replay Rooms** — Construct host analytics dashboards to track attendance metrics, watch times, and conversion funnels, plus automated replay room generation.

```
Build a host analytics dashboard (/dashboard/analytics/[webinarId]) that aggregates total registrations, live peak attendees, chat engagement rates, poll participation, and offer click-through rates. Implement an automated recording and replay pipeline where completed live streams save a video asset, generating a public replay room URL with persistent chat and active offer overlays for viewers watching after the live event concludes.
```

### Cost vs paying
