Finding the right domain name usually feels like a massive time sink. You type in your ideal name: taken. You try a clever variation: taken. Then you start manually typing in .co, .io, .ai, and .app just to see what's left. It's an endless, repetitive loop of searching across different tabs.
As someone who spins up a lot of side projects and apps, I was losing my mind doing this manually. I wanted a way to input a few base keywords, select my favorite extensions, and instantly generate a matrix of what's actually available without messing with clunky text logs or expensive aggregator subscriptions.
