Screen Sharing And Real Time Display Synchronization

via “real-time cursor and selection synchronization across distributed editors”

Real-time collaborative editing for pair programming.

Unique: Implements distributed cursor state synchronization at the VS Code editor API level, rendering remote cursors as native editor decorations rather than overlays, enabling pixel-perfect cursor positioning that respects font metrics and line wrapping. Uses Microsoft's relay infrastructure for P2P connection establishment, falling back to relay-based forwarding if direct P2P fails.

Faster and more accurate than browser-based alternatives (Figma, Google Docs) because it operates at the native VS Code editor level with direct access to cursor APIs, avoiding DOM-based rendering overhead and achieving sub-100ms synchronization latency.
