    FaTTY

    FaTTY

    Tabbed terminal for Cygwin based on mintty

    FaTTY is a tabbed terminal emulator for Cygwin based on mintty. It was created for Windows and Cygwin users who wanted the mintty experience with multiple terminal sessions inside one window. The project keeps mintty’s terminal foundation while adding a tabbed interface for switching between sessions more conveniently. It is useful for users who manage several shells, SSH sessions, or command-line workflows at the same time. The repository has been archived, so it is best treated as a legacy or historical terminal project rather than an actively maintained tool. Its main value is showing how mintty could be extended into a multi-session terminal interface before tabbed terminal workflows became more common.

    HTerminal

    HTerminal

    A new, fast and powerful system shell! Written in pure C!

    A new system shell, which is (in some regards) stronger than even Windows Command prompt, made in pure C. This terminal is fairly new, and doesn't require any complex installing process. You just download it, and then immediately use it! HTerminal has an improved console interface with modern buttons. It only has 28 commands, but it is useful none the less! And, if you're already reading this, then why not give it a try? It is completely free and takes up less than 1 MB of space + you don't even have to install it. It is ready to be used the second you download it! And, worst case scenario, you just stop using it. And if you enjoy our app, give it a rating, and maybe tell us about newly discovered bugs! It is much appreciated because it gives feedback that helps us improve HTerminal for you.
