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
If you regularly work with a fleet of servers, Netcatty is built for speed and flow:
- 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
Features

📁 SFTP + Built-in Editor

Demos
GIF previews (stored in screenshots/gifs/), rendered inline on GitHub:
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.
SFTP: drag & drop + built-in editor
Move files with drag & drop, then edit quickly using the built-in editor without leaving the app.
Drag file upload
Drop files into the app to kick off uploads without hunting through dialogs.
Custom themes
Make Netcatty yours: customize themes and UI appearance.
Keyword highlighting
Highlight important terminal output so errors, warnings, and key events stand out at a glance.
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:
