Similar kind of idea, similar in terms of features. Obviously there's a big difference in feel, Saggar being a mac app with terminals, rather than living in your existing terminal app, and I think Saggar really makes the most of that difference.

Beyond the UI, monitor & quick run windows, and rich command palette, I think the way Saggar orients your activity around your projects (e.g. a git repo) is really intuitive over the workspace model.

I'm still working on coverage for Pi and OpenCode though!

My suspicion is that Herdr will go this way with the YC relationship; they are keeping the runtime open source - the thing their terminal UI is built on- and there’s no reason cli needs to be their only target. Your app is very nice looking!
