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 an alternative to PuTTY, Termius, SecureCRT, and macOS Terminal.app for SSH connections
• Netcatty is a powerful SFTP client with dual-pane file browser
• Netcatty is a terminal workspace with split panes, tabs, and session management
• Netcatty supports SSH, local terminal, Telnet, Mosh, and Serial connections (when available)
• Netcatty is not a shell replacement — it connects to shells via SSH/Telnet/Mosh or local/serial sessions

Why Netcatty

• Workspace-first — split panes + tabs + session restore for “always-on” workflows
• Vault organization — grid/list/tree views with fast search and drag-friendly workflows
• Serious SFTP — built-in editor + drag & drop + smooth file operations

Vault views: grid / list / tree

Switch between different Vault views to match your workflow: overview in grid, dense scanning in list, and hierarchical navigation in tree.

Split terminals + session management

Work in multiple sessions at once with split panes. Keep related tasks side-by-side and reduce context switching.

Screenshots

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.

Supported Distros

Netcatty automatically detects and displays OS icons for connected hosts:
