Introduction
Modern collaboration tools rely heavily on real-time communication.
I wanted to experiment with building a Google Meet-style meeting system but with a lightweight architecture.
Instead of using heavy media servers, I explored a peer-to-peer architecture using WebRTC combined with a cloud backend.
The result was a working video meeting system that supports:
multi-user video calls
real-time chat
participant grid layout
dynamic speaker detection
All of this now powers the meeting infrastructure inside Explyra Suite.
Architecture Overview
The system is based on three main components.
- WebRTC
Used for peer-to-peer audio and video streaming.
- Firebase
Used for:
signaling
room creation
short codes
meeting links
- Frontend
Built using standard web technologies:
HTML
CSS
JavaScript
How Signaling Works
WebRTC requires a signaling mechanism to exchange connection details.
In this system Firebase handles:
session descriptions
ICE candidates
room participants
Typical flow:
1 User creates a meeting
2 Firebase generates a short room code
3 Participants join using the link
4 WebRTC establishes peer connections
Participant Layout
To keep the UI simple and usable:
active speaker appears on top
other participants appear in a grid list
camera previews can be expanded
This is similar to modern meeting tools.
Performance Results
In testing the system handled around:
~200 participants
The video quality remained stable because WebRTC dynamically adapts bitrate.
Challenges
The main challenges were:
peer connection management
browser compatibility
bandwidth optimization
Managing multiple peer connections in large rooms requires careful handling.
Why I Built This
This experiment eventually became part of a larger project called Explyra Suite, a productivity platform combining multiple tools in one ecosystem.
Some modules include:
booking system
attendance management
CRM
developer tools
meeting system
Final Thoughts
Building real-time communication systems is incredibly interesting.
WebRTC combined with serverless backends can power surprisingly capable applications without massive infrastructure.
If you are experimenting with similar systems, I would love to hear about your architecture.
