MobaXterm vs Tabby

MobaXterm combines remote-computing tools and Unix commands in a Windows application. It supports remote sessions over SSH, Telnet, Rlogin, RDP, VNC, XDMCP, FTP, SFTP, Mosh, and Serial, among other listed protocols. Its embedded X server supports OpenGL and extensions for running remote graphical applications on Windows. An SSH session can open a graphical SFTP browser for transferring files between a computer and a remote server. The terminal includes Unix commands, and additional tools can be added through downloadable plugins or the MobApt package manager. The session manager can route connections through an SSH gateway before reaching an end server. MobaXterm is offered as a single executable that can run from a USB stick without admin rights. The Home Edition has limits of 12 sessions, 2 SSH tunnels, and 4 macros; its license does not obligate the maker to provide technical assistance or maintenance. Professional Edition costs $69 per user per year, with first-year updates and optional renewal. The maker, MobaXterm, was founded in 2008 and is headquartered in Toulouse, France.

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.
