A lot of this functionality can be done by using multiple windows in Safari. Drag a tab out into its own window: boom! split browsing. (But in Safari I'm not limited to 2)

I use that a lot for the same use-case as the "sub pages" here: drag a tab into its own window, then command-click to my heart's content. When I'm done, the whole window gets closed. (Also this is without even using tab groups)

And Apple's Handoff already does the work of maintaining a seamless browsing experience between devices.

I do wish you luck and hope you find some true value differentiators.

Yeah, I concur. Furthermore, I can use macOS's spaces for different workspaces and put different browser tabs and windows into different spaces for work, fun, etc.

To the OP: I will say that seeing the tree of how I got to the current page sounds interesting if I'm researching something. However, the vast majority of my browsing is just that – browsing. I'm not usually researching something. (So maybe I'm not the target audience?)

> You can rename your pages to organize yourself and find them faster

Yeah, I don't want a tool that makes me do more work. I'm never going to rename my pages, just like I'm not going to tag all of my photos or emails or files so that the Find function can be more efficient. I just don't have time for that. If there's no way to automate it, then I don't need that feature.

Also, just want to say that your logo looks an awful lot like Apple's SiriShortcuts app logo. Might be worth changing it up.
