CST VerdictBased on our analysis of available product data, here is our conclusion:
Security training leads and red teamers running internal skill assessments will get immediate value from exploit_me because the 14 progressive vulnerability levels let you scaffold difficulty without building custom labs from scratch. The ARM/ARM64 architecture and 960 GitHub stars signal active community validation for realistic exploitation scenarios. Skip this if your team needs a commercial platform with instructor dashboards, scoring automation, or compliance reporting; exploit_me is deliberately a bare-bones training primitive, not an LMS.
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.
