CST VerdictBased on our analysis of available product data, here is our conclusion:
Security teams building internal red team muscle or running periodic skills assessments will find echoCTF's real infrastructure approach more useful than canned simulation platforms. You get a free, self-hosted framework that runs actual vulnerable systems rather than emulated scenarios, which means your team trains on the messy realities of misconfiguration and lateral movement they'll actually encounter. Skip this if you need managed competitions with minimal ops overhead or multitenancy for hundreds of concurrent users; echoCTF demands hands-on infrastructure work and a smaller, committed player base.
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.
