I m an indie developer and use both macOS and Windows for development. Most of my indie game work is done in Godot on Windows.I started using AI coding agents a few months ago, and one problem kept bothering me: Windows doesn t have a simple and reliable equivalent to tmux or screen. If I accidentally closed a terminal window, the agent session running inside it was gone too.I tried tmux through MSYS2. It sort of worked, but it would sometimes stop responding for no obvious reason.That s why I built qscreen. It provides the small subset of tmux features that I actually need, with native PowerShell support as the main goal. As long as the computer stays on and the qscreen daemon is still running, closing the terminal won t kill the session.Claude and Codex helped a lot while building this. I love these guys.Using qscreen is pretty easy. Download the `.exe` and run it. The commands I use most often are:qscn - creates a new session if there isn t one.qscn ls - list all sessions.qscn attach Id - attaches to a specific session.Press Ctrl+B , then s to open the session list. From there, you can switch sessions or create and close them. Ctrl+B ? to see the keyboard shortcuts.I m pretty happy with the current feature set, but I d love to hear what other people think. Maybe WinGet distribution should be next?Project page: https://github.com/dualface/qscreenPS: I only discovered psmux when qscreen was already nearly finished. :-D
