Scilla

Scilla is a Go-based information-gathering utility for authorized network and web reconnaissance. It combines DNS analysis, subdomain discovery, directory enumeration, and port scanning within one command-line application. Subdomains can be collected through wordlists, web crawling, and selected public data sources. Directory discovery can use custom wordlists while filtering status codes and redirect behavior. Port scans can target individual ports, ranges, common services, or full ranges. Results can be exported as JSON, HTML, or plain text, and a report command combines several reconnaissance stages. Scilla can be installed through Go, Homebrew, Snap, Docker, or source builds on supported systems.
