Kastell

Single CLI to provision, secure, harden, and manage the full lifecycle of self-hosted servers

Servicefreeglobal

Kastell is a single CLI tool for the full lifecycle of a self-hosted server — provisioning, security auditing, hardening, backup, and monitoring — replacing a fragmented mix of tools like Lynis and OpenSCAP that each have their own format and learning curve. It's aimed at server operators who want one consistent tool that scans, fixes, and hardens their infrastructure instead of juggling several disconnected ones.
