Vetted Intelligence Submission

Operational resources may be submitted for manual review and possible inclusion within The OSINT Vault intelligence ecosystem.

The OSINT Vault does not function as an open directory. Platforms considered for inclusion undergo manual operational review based on investigative value, infrastructure quality, reliability, accessibility, and long-term viability.

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.

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.
