Comments
I built SpiderFoot.app to make common OSINT checks accessible from a browser without requiring local setup. The goal is to keep username, email, and IP findings organized, transparent, and useful as leads for careful, authorized research. I would especially value feedback on source coverage and how clearly the results communicate uncertainty.
