Based on 10,000 monthly active users, average 20 minutes of calls per user per month (200,000 minutes/month)
“Self-hosted WebRTC costs $1,500–$3,000 to set up once. Then $0 per minute forever. At 10,000 users, that’s $142,000–$288,000 saved over 3 years compared to Agora or Twilio. For a messaging website, this is not a technical decision — it’s a financial one.”
✅ Primocys implements self-hosted WebRTC on every WhatsApp clone website: We set up your own TURN/STUN servers (Coturn on AWS) so voice and video calls work across all NAT types and firewalls — the same reliability as Agora, at zero per-minute cost. Your call data never leaves your servers. This is a non-negotiable part of every Primocys messaging website build. See our full WebRTC vs Agora comparison →
Understanding the whatsapp clone website vs app cost difference is one of the first decisions every founder faces. A build whatsapp like website approach — using Next.js + React + Socket.io — gives you a browser-based platform with no App Store dependency. A mobile app (Flutter) lives on the device. Below is a full side-by-side breakdown:
All prices below represent the messaging web app development cost for the web platform only — Next.js frontend, Node.js backend, Socket.io real-time, PostgreSQL database. These are real messaging web app development cost India rates — 60–70% cheaper than US or UK agencies for the same quality output. Adding the Flutter mobile app to any tier adds only 20–25% due to shared backend infrastructure.
📌 The most important row in this table: Voice Calls at $2,500–$5,500: This is the feature that saves you the most money in the long run. Self-hosted WebRTC costs $2,500–$5,500 once to implement. Agora would cost $3,960/month ongoing. The implementation cost pays for itself in the first month after launch. Every month after that is pure savings. Primocys implements self-hosted WebRTC with Coturn TURN server on every messaging website we build.
