I use Stack browser. Not quite what you describe, but a step in that direction. https://stackbrowser.com/

After taking a glance at their website, this seems quite similar to the arc browser. Have you tried arc, and if so how do you think they compare?

To save you time trying it out, their implementation of tiling is better than that of Arc. Unfortunately it suffers the same problem most mainstream browsers do: broken pinned tabs, and there is no pinned tab groups like Arc

[nsonha]

correct: there IS tabs/groups pinning, just no extensions support, for now.
