Netcatty is an open source SSH client and remote server management application designed for developers, DevOps engineers, and system administrators. Rather than being a simple terminal emulator, it combines SSH, SFTP, port forwarding, terminal management, and workspace organization into a single desktop application. Available for Windows, macOS, and Linux, Netcatty aims to streamline remote server administration with a modern interface and powerful productivity features.
Managing multiple remote servers often means juggling several terminal windows, file transfer tools, and SSH configurations. Netcatty brings these tasks together into one application with organized workspaces, split terminals, and integrated file management.
Unlike traditional SSH clients that focus solely on terminal access, Netcatty provides a complete remote administration environment with support for SSH, Telnet, Mosh, serial connections, SFTP, jump hosts, proxy servers, and port forwarding.
Key Features of Netcatty
Modern SSH Workspace
Netcatty organizes servers into a built-in Vault, allowing users to manage large numbers of hosts using grid, list, or tree views with fast search capabilities. This makes navigating complex infrastructures much easier than maintaining separate configuration files.
Split Terminal Support
Multiple terminal sessions can be displayed simultaneously using horizontal and vertical split layouts. This is especially useful when monitoring several servers or comparing outputs side by side.
Built-In SFTP Client
The integrated SFTP browser supports drag-and-drop file transfers, remote file editing, and directory management without requiring a separate application.
Multiple Connection Protocols
In addition to SSH, Netcatty supports Telnet, Mosh, and serial connections. It also includes support for jump hosts, proxy servers, and legacy SSH algorithms for compatibility with older systems.
Port Forwarding
The application supports local, remote, and dynamic port forwarding with reusable configurations and automatic startup, making it suitable for development, database access, and secure tunneling.
Secure Authentication
Netcatty supports password authentication, SSH keys, certificates, and SSH agent forwarding, providing flexibility for both personal and enterprise environments.
Cloud Configuration Sync
Users can synchronize their configuration across multiple devices using supported cloud storage providers such as GitHub, Google Drive, OneDrive, or Amazon S3.
AI Assistant
Recent versions include an integrated AI assistant that helps automate terminal workflows and assists with remote administration tasks directly within the application.

Netcatty v1.1.69 Release Notes:✨ Release HighlightsNetcatty v1.1.69 is a broad foundation-and-reliability release. It introduces the building blocks for first-party plugins, makes Catty sessions more durable, strengthens multi-device sync and live port forwarding, and improves terminal performance alongside several everyday workflow refinements.🧩 A foundation for Netcatty pluginsNetcatty now includes a plugin contract, SDK, CLI tooling, and a working example plugin. The new foundation covers validated package loading, bounded streaming, cancellation, secret references, and safer runtime boundaries so future plugins can integrate with the app through a consistent, hardened interface.🤖 More durable Catty sessionsLong-running Catty work is more resilient. Terminal context is preserved more carefully as conversations grow, saved tool outputs survive app restarts, UTF-8 content remains intact across streamed chunks, and idle agent sessions can close automatically without racing against fresh activity.🔄 Convergent sync and accurate live port forwardingMulti-device sync now uses a convergent data model with a guarded migration path, including correct handling when cloud settings are applied during the first merge. Port forwarding status also tracks the real backend state across reconnects, retries, multiple windows, tray actions, and replaced tunnels instead of drifting away from what is actually running.⚡ Smoother terminals and remote sessionsTerminal output arriving in many tiny network chunks is coalesced for smoother rendering, and the WebGL renderer can recover after a graphics-context loss. This release also updates bundled Mosh support to MoshCatty 0.1.8, keeps non-hibernated background tabs active, makes batch tab closing consistent, and improves SFTP secondary-authentication recovery.🎨 Better fonts, editing, and system visibilityThe snippet editor now supports find and replace, while terminal settings can use locally installed CJK fonts with primary and fallback choices. System Manager reports ImmortalWrt metrics more reliably and totals real mounted-disk capacity without double-counting shared or image-backed volumes. Disk capacity values now stay readable with at most two decimal places, and the Netcatty wordmark remains consistent when users change the interface font.Download based on your OS:
