What is Netcatty
Netcatty is a modern SSH client and terminal manager for macOS, Windows, and Linux, designed for developers, sysadmins, and DevOps engineers who need to manage multiple remote servers efficiently.

- Netcatty is a terminal workspace with split panes, tabs, and session management

Main Window
The main window is designed for long-running SSH workflows: quick access to sessions, navigation, and core tools in one place.
Vault Views
Organize and navigate your hosts using the view that best fits the moment: grid for overview, list for scanning, tree for structure.
Split Terminals
Split panes help you monitor multiple servers/services at the same time (deploy + logs + metrics) without juggling windows.
