What OSINT UI is
OSINT UI is a professional Open Source Intelligence (OSINT) platform: 20 investigation tools — email, phone, domain, IP, username, data-breach, image, cryptocurrency and Telegram analysis, and more — all from a single web desktop, built for analysts, journalists, security teams and law enforcement.
It's not just another tool: it's a platform. The difference is Investigation Graph, the engine that cross-references the output of the other tools on the same target (a person, a domain, a company) and draws it as a relationship graph — instead of opening twenty tabs and writing down what you find by hand.
Three design principles
- Correlation, not a pile of separate tools. Every source Investigation Graph queries feeds the same graph: an email seen by the domain analyzer, a data breach, and a GitHub commit can end up being the same node with three sources, not three unrelated findings.
- Your keys, your control (BYOK). Tools that need a third-party API (Shodan, VirusTotal, Hunter...) use your own keys, encrypted server-side. Your quota is never shared with another user, and you decide which providers to connect.
- We don't store your searches. The selector you analyze isn't permanently logged unless you explicitly save it to Saved Investigations. See Security & privacy.
Languages and access
The platform is bilingual (Spanish/English) and works in any modern browser, no install required. Everything lives at osint-ui.com/app once you register.
