What it is

Tabby is a free, open-source terminal app for Windows, macOS, and Linux. It connects to local shells, serial devices, SSH servers, and Telnet hosts, and supports shell environments including PowerShell, WSL, Git-Bash, Cygwin, and CMD. Its SSH2 client has a connection manager, while the serial terminal offers connection profiles and input modes. SSH sessions support SFTP and Zmodem file transfers, X11 and port forwarding, jump hosts, and agent forwarding. Tabby can restore open tabs and split panes after you leave the app, and nested panes support simultaneous input. SSH secrets and configuration can be stored in an encrypted container; an optional password manager uses a master passphrase. Customization includes CSS themes, color schemes, shortcuts, and plugins. Other listed capabilities include GPU acceleration, session sync, scripting, portable mode, Explorer integration, and WinSCP integration. The app is described as forever-free FOSS. The page provides download and GitHub links but states no dedicated support terms.
