Acceptance is selective and not guaranteed. Priority is given to operationally valuable investigative infrastructure. Submissions involving scamware, malware, unstable infrastructure, deceptive aggregators, or spam tools are rejected without response.

Nicole Hurey

I build OSINT tools that work the way investigations actually run · browser-based, structured, and fast. No registration. No fluff. Every tool on this site is something I use or have needed in real investigative work. If something is wrong I want to know. If something's missing, I'll build it.
