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!
