Marie Kondo for your browser

I built WhyTab because I was sick of OneTab.

That’s the whole origin story. I had OneTab, like everyone else. And like everyone else, I’d accumulated about 20,000 tabs in it — an undifferentiated mass of things I once thought I’d come back to. It had become a graveyard, not a tool.

The problem isn’t that tab managers don’t exist. There are loads of them. The problem is that none of them matched how I actually think. When I browse the web, my tabs become research sessions — sprawling, topical, half-formed. Some things are temporary. Some things I need every day. Some things I’d love to save and revisit. Some things I should just let go of. I wanted a tool that understood these distinctions and, more importantly, forced me to make them.

So I built one.

WhyTab is aggressively minimal by design. There are no nested lists — you can’t put a collection inside a collection. This is deliberate. It forces you to categorise at one level, which means you have to actually decide what something is rather than burying it three folders deep and forgetting about it.

The key feature is Prune. Prune walks you through everything you’ve saved and asks you to make a choice: keep it, collect it properly, or let it go. It’s Marie Kondo for your browser. What sparks joy? What’s just clutter? The act of pruning isn’t just organisational — it’s a mental clearing. You come out the other end knowing what you’re actually working on and what you were just hoarding.

I sketched the layout in Figma, handed it off to Claude Code, and iterated over a couple of weeks — using it myself, getting friends to test it, refining the interactions until it felt right.

The philosophy behind WhyTab is the same one behind everything I build: create clarity by giving people simple tools to rearrange, reframe, and reprioritise what’s in front of them. Don’t add complexity. Remove it. Let people see what’s actually there.
