TermCOW is an SSH terminal for developers, sysadmins, and anyone who wants to do their work anywhere. I originally built it so I could connect to my machine at home running AI coding agents in tmux from my phone. On a phone, it’s usually either tiny unreadable text to fit the whole terminal, or confusing text reflow, flashing, and wrapping when you zoom in. TermCOW uses pan and zoom instead of text reflow, so the terminal stays stable while you work. But if you like text reflow, TermCOW supports that too. All standard SSH features are free, including password/key auth, SFTP, and encrypted credential storage. Features • SSH with password and key auth • SFTP file transfer • Encrypted credential vault • Pan and zoom for a stable desktop-class terminal • Customizable multi-state shortcuts • Port forwarding • Jump host / bastion support • Back up settings to the TermCOW service • Premium jump host service for private IP access Clean, functional, minimal UI that stays out of your way while you do real work with a desktop-class terminal from your phone.
