Security teams building internal cyber range programs for hands-on training will find HackTheArch valuable because its open-source Rails architecture keeps setup friction low and lets you customize scoring logic without vendor lock-in. The 72 GitHub stars and active Ruby community mean you're not betting on a solo maintainer, and the web-based hint system handles the tedious logistics of running live CTF events. Skip this if your organization needs a managed SaaS platform with built-in content libraries and instructor dashboards; HackTheArch requires you to author your own challenges and manage the infrastructure yourself.
Security teams running internal CTF competitions or capture-the-flag training programs should use Mellivora for its lightweight, self-hosted architecture; you get full control over challenge creation and scoring without vendor lock-in or monthly bills. With 453 GitHub stars and PHP-based deployment, it's proven enough for university programs and mid-sized security training operations that want to host their own infrastructure. Skip this if you need a managed platform with slick UX or integration into a broader security awareness suite; Mellivora requires hands-on administration and assumes your team is comfortable with open-source tooling.
