rustscan

Uses optimized Rust code to scan all 65,535 ports in as little as 3 seconds, with continuous integration tests ensuring performance doesn't regress, as highlighted in the README's speed section.

Supports custom scripts in Python, Lua, or Shell, allowing automated workflows like piping results into Nmap or running post-scan actions, which is demonstrated in the extensibility examples.

Automatically pipes discovered open ports into Nmap for detailed service and version detection, streamlining the reconnaissance pipeline as a core feature mentioned in the key features.

Built with accessibility as a core requirement, including CI testing to ensure usability for all, addressing a noted gap in penetration testing tools according to the README.
