Spec score 7.7 #15 of 26 in Port Scanner Software

What it is

RustScan is a free command-line port scanner for finding open network ports. The project says it can scan all 65,000 ports in three seconds, and discovered ports can be passed automatically to Nmap for further analysis. It supports IPv6, CIDR ranges and file input, with scripting in Python, Lua and Shell. Listed capabilities include service detection, operating-system detection and greppable-text output. RustScan describes adaptive learning that uses information about the scan environment and usage to improve over time. The project also says its continuous integration checks whether the scanner becomes significantly slower than the previous version and aims to ensure accessibility. Cargo is the only officially supported installation method, although releases and package-manager options are also listed. The installation guide recommends Docker and says its image works across systems, including Windows, which is not officially supported. The maintainer says RustScan has been tested only on Linux and that macOS or Windows may have issues; the guide also notes macOS's low open-file limit can significantly affect scanning. The project is licensed under GPL-3.0.
