A decentralized synchronization system based on multicast technology that enables seamless real-time synchronization between multiple VSCode, JetBrains IDE instances simultaneously. Compatible with VSCode forks (Cursor, Windsurf) and JetBrains IntelliJ-based IDEs (Rider, IntelliJ IDEA, WebStorm, PyCharm, etc.). No central server required - all IDEs communicate directly with each other in a peer-to-peer fashion.

• 🔄 Decentralized Architecture: No central server - direct peer-to-peer communication via multicast
• 📂 File Operations Sync: Real-time file opening and closing synchronization across all connected IDEs
• 🎯 Cursor & Selection Sync: Live cursor position and code selection synchronization with precise line/column accuracy
• 🔄 Focus Compensation: Full workspace synchronization when window loses focus, ensuring other IDEs receive the latest state
• 🔗 Multi-Instance Support: Connect unlimited VSCode and JetBrains IDE instances simultaneously
• ⚡ Zero Configuration: Automatic discovery and connection of IDE instances on the same network, with seamless departure from the network
