I built something to use for myself which is organized workspaces to work on many things with Claude in parallel with the ability to run things in VMs and linked web browsers all contained in one app. I built it mostly driven by trying to work on too many things at once and getting lost in a sea of windows and browser tabs.

It is not at all ready for public consumption (a face only a mother could love, in other words it's a bugridden mess), but I've considered polishing it and releasing it to the public either as open source or for profit.

Most of it is written with Claude and I've run into roadblocks with Claude being able to do too many things at once and am rewriting as several libraries to improve the focus for Claude agents.
