Flowsint

What it is

Flowsint is a self-hosted web app for open-source intelligence work, where entities like domains, IPs, emails, organizations, and crypto wallets are laid out on a visual graph. Built-in enrichers run DNS and WHOIS lookups, subdomain discovery, ASN and CIDR mapping, breach checks, username searches, and website crawling, adding the results as connected nodes. Security analysts and investigators run it with Docker on their own machine or a team server so case data stays local.
