Unicornscan
Unicornscan is a free network reconnaissance tool that sends asynchronous, stateless probes and records responses. Its documented scan modes include TCP SYN scans, UDP probes with protocol-specific payloads, local-network ARP discovery, and stateless TCP traceroute. Alicorn provides a web interface for reviewing results, with scan history, host and port statistics, OS fingerprinting, and network topology visualization. The pgsqldb module can export results to PostgreSQL, which Alicorn uses for storage; Alicorn also starts a PostgREST API with its web server. Optional free DB-IP Lite databases add country, city, and ASN lookups to scan output and the interface. Packages are listed for Debian, Ubuntu, Fedora, RHEL-compatible distributions, and macOS through Homebrew or DMG. Linux capabilities are set automatically so scans can run without root privileges. The Alicorn interface requires Docker and PostgreSQL. Compound scan modes that begin with ARP are limited to targets on the local broadcast domain because ARP requests cannot cross routers. The install guide directs users to the project website and GitHub Issues for support.
