Mission
The web is built on stacks. We map them — continuously, at scale, with a tiny Go crawler and a stubborn refusal to call it good enough. No black box. No bloated tags. Just a fast lookup and a public catalog you can browse, search, export.
Vision
Make the entire web's tech adoption legible — to sales, research, recruiting, and anyone curious about what powers what. A public index, fair pricing, no surprises.
LargerIO
Built by a small team. Indexed by a hungry crawler.
