In simple English
This is a replacement for your computer's built-in command window. It lets you open multiple shells in tabs, split the screen into sections, and save your remote server logins. You can change how it looks with themes and install plugins for extra features. It is free to download and use on Windows, macOS, and Linux. However, it uses more memory than traditional terminal windows.
What it is
Tabby (formerly Terminus) is a highly configurable terminal emulator, SSH (a secure way to log into remote computers over a network) and serial client built with TypeScript (a programming language that adds rules to JavaScript). It combines local shell access, remote connection management, and serial port communication into one graphical desktop application.
What it is good for
Developers and system administrators who want a polished, unified terminal app across multiple operating systems without configuring complex text-based tools like tmux.
- Saves and restores your open tabs and window layouts across restarts.
- Manages SSH, Telnet, and serial connections in a built-in connection manager.
- Extensive customization through themes, color schemes, and shortcut settings.
- Higher memory usage compared to native or lightweight terminal emulators.
- Setup is straightforward as a pre-built binary download, but building from source requires Node.js and yarn.
- Heavy reliance on plugins for advanced workspace features can lead to maintenance overhead.
