Coding Live - Lightning-Fast Real-Time Code Collaboration
A powerful VSCode extension for real-time code collaboration without cloud dependencies

Overview
Coding Live is an advanced VSCode extension that enables multiple developers to code together in real-time with sub-millisecond latency. All collaboration happens locally on your network with zero cloud dependencies, enterprise-grade security, and lightning-fast performance.
Key Features:
- Ultra-fast real-time synchronization (< 1ms latency)
- Smart cursor tracking with color-coded user indicators
- Integrated chat and activity feed
- Terminal sharing with granular permissions
- Collaborative debugging with shared breakpoints
- Code review with inline comments
- Automatic backup system with snapshots
- AES-256-GCM encryption for all communications
- Performance monitoring and metrics
Quick Start
Installation
- Install Coding Live from the VSCode Marketplace
- Open the Coding Live panel in the activity bar
- Click "Create Room" to start a collaboration session
