I like that it’s a UI.
Dagger has a nice solution for this in this space called Container Use - https://container-use.com/introduction
It does git worktree based parallelisation as well.
Edit: Ah! I see you mentioned several tools. Sorry I saw the repo and immediately thought of container use as I have been planning to give it a go this week. Did you happen to try it too? And where did it breakdown?
I'll take a look. I think containers are overkill for my type of workflow. I'm working on a project where dependencies don't change often so I'm not worried about a CLI agent installing something on my machine and breaking things.
