CST VerdictBased on our analysis of available product data, here is our conclusion:
Small security teams and junior-heavy programs need a CTF platform that doesn't require DevOps overhead to stand up; BetterMotherFucking CTF delivers that by stripping out complexity entirely and letting you host competitions in minutes. The equal-point scoring model removes artificial difficulty tuning, so you're testing actual skill gaps instead of guessing at challenge calibration. Skip this if your organization needs role-based access controls, team management at scale, or scoring flexibility; the simplicity that makes it fast to deploy is the same simplicity that disappears when you have 50 concurrent players or need weighted categories.
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.
