# How to Vibe Code Your Own Crowdcast (and Stop Paying for It) > Where the world gathers - Site: https://crowdcast.io - Category: SaaS - Platforms: Web app - Verdict: **Don't bother** (22/100 vibecodeable) - Estimated effort: 6+ months of full-time work for a complete feature-parity clone ## Verdict You can build a static webinar landing page clone over a weekend, but the core WebRTC multi-party video studio and RTMP transcoding infrastructure make a full clone a serious engineering undertaking that is vastly cheaper to buy. Building a personal-use clone of Crowdcast exposes you to brutal engineering roadblocks. While putting together a Next.js registration page and a database is trivial, orchestrating a browser-based video studio for 11 simultaneous participants requires a Selective Forwarding Unit (SFU) architecture like LiveKit or Daily, TURN/STUN relay servers, and complex media negotiation. Furthermore, supporting OBS/Ecamm RTMP inputs and transcoding streams out to YouTube and Twitch demands heavy media server infrastructure (FFmpeg/Go/Rust pipelines) that will quickly break a solo developer's workflow and hosting budget. Unless your goal is specifically to learn WebRTC internals from scratch, paying for the platform is mathematically more rational than spending months wrestling with media streams. ### What you can't replicate - The battle-tested WebRTC media routing architecture handling thousands of concurrent viewers without audio desync - Direct creator integrations and brand trust built over a decade - Low-latency global edge media distribution network ## What it does All-in-one, browser-based live video streaming and webinar platform for workshops, virtual summits, and online courses. ### Core features - Built-in registration landing pages with custom URLs - Multi-party studio supporting up to 11 people on screen simultaneously - Real-time interactive chat, polls, and timestamped Q&A - HD live video streaming with instant replay storage and downloads - RTMP ingestion and multistreaming to external platforms (YouTube, Twitch, Facebook) - Stripe integration for paid events, ticketing, and donations - Automated email notifications and attendee analytics ## The business ### Pricing - Lite: $49/mo - Pro: $89/mo - Business: $195/mo Founded 2015. Team size: ~2-10. ## The hard parts - Building an ultra-low latency SFU-based WebRTC multi-party video conferencing engine for 11 simultaneous speakers - Handling RTMP stream ingestion, transcoding pipelines, and outbound multistreaming via FFmpeg/media servers - Synchronizing high-throughput chat, live polls, and upvoted Q&A state across thousands of concurrent viewers - Implementing usage-based billing logic tracking peak live concurrent attendance and overage calculations ## How to vibe code Crowdcast ### Prerequisites - Node.js (free): Required runtime for frontend and backend tooling - GitHub (free): Source code management and deployment pipelines ### Recommended AI tools - Cursor: AI code editor for iterating rapidly on React components, UI layouts, and frontend state management - Claude Code: Agentic terminal coding tool for scaffolding backend APIs, database schemas, and multi-file workflows ### Stack - Frontend: Next.js with Tailwind CSS - Backend: Next.js API routes / Node.js server - Database: Turso (SQLite at the edge) - Auth: better-auth - Payments: Stripe - Other: LiveKit for WebRTC video rooms, Resend for transactional emails ### Hosting - Vercel (Hosting the Next.js frontend and serverless API endpoints): $0-20/mo - Fly.io (Hosting the WebRTC SFU / media server (LiveKit) for real-time video rooms): $5-15/mo ### Build guide 1. **Scaffold Project and Authentication** — Initialize the Next.js project repository with Tailwind CSS, configure Turso SQLite database bindings, and implement user authentication using better-auth for hosts and attendees. ``` Create a new Next.js 16 project with TypeScript and Tailwind CSS v4. Configure a Turso SQLite database connection using Drizzle ORM with tables for users, events, registrations, chat_messages, and polls. Implement better-auth with email/password authentication and a user profile schema. Set up protected layout routes for host dashboards and public event landing pages. ``` 2. **Event Landing Pages and Registration Flow** — Build the dynamic event registration pages where users can view event details, submit custom registration info, and receive instant confirmation links. ``` Build a dynamic event page at /e/[slug] using Next.js App Router. If the event is upcoming, display a registration landing page with host bio, title, cover image, and a one-click registration form. Upon registration, store the attendee record in Turso, issue a unique token cookie, and render the live/recap room view depending on the event status. Include a host dashboard route at /dashboard/events for creating and editing events with custom descriptions and dates. ``` 3. **Real-Time Chat, Polls, and Q&A Subsystems** — Implement the interactive audience sidebar featuring real-time chat messages, active polls with voting tallies, and upvoted timestamped Q&A threads. ``` Implement a real-time engagement sidebar for live events using WebSockets or Pusher channels. Create React components for a live chat box with message history, a polling widget allowing hosts to create and publish live votes with percentage bars, and a Q&A tab where attendees can submit questions, upvote existing questions, and hosts can mark questions as answered with video timestamp links stored in SQLite. ``` 4. **WebRTC Video Studio Integration** — Integrate a WebRTC video conferencing layer (using LiveKit) to allow up to 11 participants to join the stage, manage audio/video tracks, and share screens. ``` Integrate LiveKit SDK into the event room view to support a multi-party video studio. Build host controls to invite registered attendees or co-hosts 'up on screen' (promoting them from viewer to publisher tokens). Create grid layouts for up to 11 simultaneous video feeds, mute/unmute audio/video toggles, screen sharing capabilities, and a 'green room' waiting area for speakers before going live. ``` 5. **Stripe Ticketing and Monetization** — Incorporate Stripe checkout sessions to support paid ticketed events, sliding scale pricing, and creator donations. ``` Integrate Stripe billing into the event creation flow. Allow hosts to set ticket prices (fixed or donation-based). When an attendee attempts to register for a paid event, redirect them to a Stripe Checkout session, handle webhook events securely to record ticket purchases, grant event access upon payment success, and display a purchase confirmation receipt on the registration page. ``` 6. **Automated Email Notifications and Replays** — Set up transactional email reminders via Resend and record live sessions for instant video replays. ``` Configure Resend API to send automated transactional emails: a registration confirmation email with the unique event link upon signup, and a reminder email 1 hour before event start. Implement a recording storage handler using Cloudflare R2 or local volume storage that saves stream archives upon event completion and makes them instantly available at the exact same event URL for replay. ``` ### Cost vs paying **Starting costs (one-time):** - Domain registration: $12 one-time - Total: ~$12 one-time **Ongoing costs (monthly):** - Vercel Hobby/Pro hosting: $0-20/mo - Fly.io WebRTC SFU server: $5-15/mo - Turso database & Resend email: $0/mo - Total: ~$5-35/mo - Paying for the SaaS instead: $49/mo to $195/mo (Lite to Business tiers) - Build time: 120-160 hours - AI tool credits: $40 (2 months of Cursor/Claude Pro) - Break-even: 1 month (compared to Business tier) ## Sources - [Crowdcast Official Website & Pricing](https://crowdcast.io) - [Crowdcast Features & Product Documentation](https://crowdcast.io/product)
