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

> Video Conferencing, Cloud Calling & Screen Sharing

- Site: https://webex.com
- Category: Enterprise Communications
- Platforms: Web app, macOS app, Windows app, iOS app, Android app
- Verdict: **Don't bother** (12/100 vibecodeable)
- Estimated effort: 6+ months of full-time work for a crippled 1:1 video subset

## Verdict

Build a personal 1:1 video chat subset with Daily.js, but keep paying for Webex if you need enterprise UCaaS infrastructure.

Replicating Webex is impossible for a solo developer because its core value depends on global-scale SFU server topologies, complex PSTN carrier connections, and strict enterprise compliance certifications. While you can stitch together a basic 1:1 WebRTC video calling app using modern APIs, you cannot replicate enterprise telephony or carrier-grade multi-party media routing alone.

### What you can't replicate

- Global carrier-grade PSTN phone system integration and SIP trunking
- Enterprise compliance and zero-trust security infrastructure
- Hardware desk phone and room system ecosystem

## What it does

Unified communications-as-a-service (UCaaS) and enterprise collaboration suite providing meetings, calling, messaging, and event management.

### Core features

- Real-time multi-party video/audio conferencing
- Selective Forwarding Unit (SFU) media routing
- Persistent team messaging and file sharing
- Interactive whiteboarding and screen sharing
- AI meeting summaries and transcriptions
- Cloud-based telephony/calling integrations
- Breakout rooms and live polling
- Centralized admin and analytics control hub

## The business

### Pricing

- Free: $0/mo — Basic meetings up to 50 minutes and 100 participants.
- Webex Meet: $13.50/mo — Extended meetings and cloud recording.
- Webex Suite: $25/mo — Comprehensive collaboration package.

### Funding

$47.0M raised.
- Series C (1999)
- Series U (2000)
Investors: Summit Partners, New Enterprise Associates (NEA), Walden International

Founded 1995.
Team size: 10000+.

## The hard parts

- Global-scale Selective Forwarding Unit (SFU) architecture for low-latency WebRTC streams
- PSTN carrier integration and global telephony/SIP trunking compliance
- End-to-end encryption (E2EE) key management and strict enterprise compliance frameworks
- Cross-platform native hardware desk integration and audio/video device management

## How to vibe code Webex

### Prerequisites

- Node.js (Free): Required runtime for building the web frontend and signaling server.
- GitHub (Free): Source control and deployment pipeline.

### Recommended AI tools

- Claude Code: Best-in-class agentic coding tool for scaffolding full-stack web applications and managing complex multi-file logic.
- Cursor: Ideal for iterative UI work and reviewing code diffs during frontend development.

### Stack

- Frontend: Next.js with Tailwind CSS
- Backend: Next.js API routes with LiveKit server integration
- Database: Turso (SQLite at the edge)
- Auth: better-auth
- Payments: None
- Other: LiveKit for WebRTC video routing, OpenAI Whisper for audio transcription, Resend for email invitations

### Hosting

- Vercel (Hosting the Next.js web application frontend and API routes): $0-20/mo
- Fly.io (Hosting the self-hosted LiveKit SFU media server for WebRTC rooms): $5-15/mo

### Build guide

1. **Project Scaffolding & Database Setup** — Initialize the Next.js application, configure Tailwind CSS, set up Turso SQLite connection, and implement better-auth for user management.

```
Initialize a new Next.js project with Tailwind CSS and TypeScript. Configure Turso SQLite using Drizzle ORM for database operations. Implement better-auth with email/password and session handling. Create a clean dashboard layout with a sidebar for Meetings, Messaging, and Settings. Ensure all TypeScript strict checks pass and structure the repository cleanly with modular directories.
```

2. **Persistent Messaging & Chat Rooms** — Build team messaging channels, direct messages, and real-time text exchange using WebSockets or server-sent events.

```
Create a persistent messaging subsystem in Next.js using Turso tables for channels, messages, and direct messages. Implement a responsive chat UI with message history, markdown support, and real-time updates. Add API endpoints for sending messages, uploading attachments via Cloudflare R2, and listing user channels. Ensure proper error states and loading skeletons are handled.
```

3. **WebRTC Video Room Infrastructure** — Integrate LiveKit SDK for managing multi-party video rooms, screen sharing, and audio/video controls.

```
Set up LiveKit integration for video conferencing rooms. Implement token generation API routes for authenticated users joining specific room IDs. Build a video conferencing UI featuring grid layouts for participants, mute/unmute audio, camera toggle, screen sharing controls, and participant list sidebars. Handle connection drops and reconnection states gracefully.
```

4. **AI Meeting Summaries & Transcription** — Incorporate audio recording storage and Whisper API transcription pipelines to generate post-meeting summaries.

```
Implement an audio recording pipeline that uploads meeting audio chunks to object storage. Build a background worker or server action that sends recorded audio files to the OpenAI Whisper API for transcription. Use Claude or GPT models to parse the transcript into key action items, highlights, and a concise meeting summary, displaying results in a dedicated meeting details view.
```

5. **Control Hub & User Management** — Build an admin dashboard for user role management, organization settings, and basic usage analytics.

```
Develop a centralized Control Hub admin portal. Build views for managing organization users, assigning roles (admin, user), viewing aggregate meeting usage statistics, and configuring security compliance policies. Secure these routes with role-based middleware linked to better-auth sessions.
```

6. **Polish, Error Handling & Deployment** — Add comprehensive error boundaries, responsive layout adjustments, and deploy the application to Vercel and Fly.io.

```
Perform a comprehensive polish pass across the entire application. Add toast notifications for user actions, empty states for channels and meetings, loading spinners for async operations, and robust error boundaries. Verify production builds for Next.js on Vercel and ensure environment variables are documented in a .env.example file.
```

### Cost vs paying

**Starting costs (one-time):**

- Custom domain: $12/yr
- Initial AI API credits: $20 one-time
- Total: ~$32 one-time

**Ongoing costs (monthly):**

- Vercel & Fly.io hosting: $15/mo
- OpenAI Whisper & LLM usage: $10/mo
- Total: ~$25/mo

- Paying for the SaaS instead: $25/mo (Webex Suite)
- Build time: 80-120 hours
- AI tool credits: $20/mo (Claude Pro / Cursor)
- Break-even: Never (built for learning, not savings)
