ethersync/ethersync: Editor-agnostic, real-time collaborative editing of local text files.

Ethersync is an open-source tool that enables real-time collaborative editing of local text files across different editors. It features encrypted peer-to-peer connections without requiring a server, supports multiple editors including VS Code and Neovim through plugins, and allows developers to see each other's cursors and selections while working on shared projects. The tool works on Linux, macOS, Android, and Windows Subsystem for Linux, with a simple installation process and JSON-RPC protocol for creating new editor plugins.
