env.sync.local is a distributed secrets synchronization tool designed for local networks, offering robust security through AGE encryption. This tool allows you to securely sync your .env style secrets across multiple machines using SCP/SSH with at-rest encryption. The latest version, v2.0, introduces a major rewrite in Go, providing a single, statically compiled binary that eliminates the need for bash scripts. Key features include built-in AGE encryption, improved performance, and better cross-platform support for Linux, macOS, and Windows (WSL2). The tool is designed for easy expansion, allowing new machines to be added without modifying existing ones, and supports automatic discovery using mDNS/Bonjour. It also offers transparent decryption, version control, and a backup system to ensure data integrity. With its secure by default configuration, env.sync.local is ideal for developers looking to manage secrets efficiently across distributed environments.
