Konsole vs Tabby

Konsole is a terminal emulator for running a command shell and controlling a computer through a text-based command line. It is listed for Linux, Windows, and macOS and is free and open source under GPL-2.0+. Tabs and multiple profiles organize sessions; profiles can also automate common commands, including SSH connections to another machine. A tab can be split into left-right or top-bottom views, and its layout can be saved to a file. Konsole supports bookmarks, searching, and saving output or scrollback as a text or HTML file. Monitoring can notify users about silence, activity, a shell prompt, or a finished process. With shell integration enabled, it distinguishes prompts, input, and output and provides visual hints for commands that resulted in errors. A D-Bus interface allows software to control Konsole windows and sessions. Linux installation options include application stores, distribution package managers, and Flathub. The project links to Windows and macOS platform pages, including nightly installers for Windows and macOS ARM and Intel; those builds are intended for testing and come from the latest development branch.

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.
