Flowsint is an open-source OSINT graph exploration tool for ethical investigation, cybersecurity analysis, and reconnaissance. It represents relationships between entities in a visual graph and uses automated enrichers for domains, IP addresses, ASNs, CIDRs, websites, social profiles, organizations, email addresses, phone numbers, cryptocurrency wallets, and other investigation data. Enrichers include DNS and reverse-DNS resolution, subdomain discovery, WHOIS, website crawling, link and text extraction, username searches through Maigret, breach checks, and cryptocurrency transaction and NFT lookups; an N8n connector supports workflow integration.
The project is organized into a frontend application, a FastAPI server, core orchestration and vault utilities, Pydantic data types, and enricher modules. It uses PostgreSQL and Neo4j for data storage, Redis and Celery for task processing, and provides authentication, graph database integration, REST endpoints, and real-time event streaming. The application can be run locally or deployed on a server with Docker and Docker Compose, with data stored on the operator's machine. It is intended for lawful, ethical investigation and prohibits unauthorized intrusion, surveillance, harassment, doxxing, and other misuse.
