Tabby

What it is

Tabby is a free, open-source terminal application for Windows, macOS, and Linux. It connects to local shells, serial devices, SSH servers, and Telnet hosts. Its integrated SSH2 client has a connection manager, while the serial terminal provides connection profiles and input modes. SSH sessions support SFTP and Zmodem transfers, X11 and port forwarding, jump hosts, and agent forwarding.

Tabby can restore open tabs and split panes after the app is closed, with nested pane layouts and simultaneous input across panes. SSH secrets and configuration can be stored in an encrypted container; an optional password manager uses a master passphrase. Supported shells include PowerShell, PS Core, WSL, Git-Bash, Cygwin, Cmder, and CMD. Customization includes CSS themes, color schemes, shortcuts, and plugins. The listed capabilities also include GPU acceleration, scripting, and session sync. Tabby provides download and GitHub links, but no dedicated support terms are stated.
