A lightweight real-time video communication platform built with WebRTC and Socket.io, designed for fast peer-to-peer calling with minimal setup and infrastructure overhead.
- Instant room creation and joining (no authentication)
- Peer-to-peer video communication using WebRTC
- Socket.io-based signaling layer
- Connection recovery and reconnection handling
- Low-latency responsive UI
- Minimal flow optimized for speed and accessibility
- Self-hosted signaling server
Lowcall is a real-time communication platform focused on simplicity and resilience. It was built around the idea of removing friction from video calling — users can instantly create or join a room without accounts, setup, or extra steps.
The project was also an exploration of WebRTC behavior under unstable network conditions and the challenges of maintaining peer connections in real-world environments.
Direct peer-to-peer connections handle media streaming, while Socket.io is used only for signaling and room coordination.
A lightweight WebSocket-based signaling server manages session discovery and peer connection setup.
Deployed on Linux with Nginx reverse proxy, SSL configuration, and manual server management.
