It’s a GTK4 app built on Ghostty/libghostty, with split panes, workspaces, vertical tabs, notifications, project-aware tabs (shows favicons/logo automatically), and an in-app browser so terminals and docs/tools can live side by side.
I started it because I wanted something tmux-like for modern GUI workflows on Linux, but native and not Electron, there is cmux but only available on macos (prettymux compiles on windows and macos too but not tested for now there)
It’s open source: https://github.com/patcito/prettymux
Would love feedback from people who use tmux, Ghostty, or struggle with lots of terminals/browser tabs/parallel tasks.
