 Dockyard is a **terminal-based Docker management tool** built specifically for **resource-constrained VPS servers**.  
 Written in **Rust** with performance as a first-class concern, it provides complete container and image lifecycle management with real-time monitoring—all with minimal overhead and an easy-on-the-eyes TUI.
