CST VerdictBased on our analysis of available product data, here is our conclusion:
Security teams building internal red teams or training junior analysts on a budget should use Labs-Pentest for hands-on penetration testing practice without licensing costs. Its 272 GitHub stars reflect active maintenance and a collection of real CTF challenges that beat sanitized vendor labs for teaching actual exploitation technique. Skip this if your goal is measuring individual competency through formal assessments; Labs-Pentest is a free practice ground, not a credentialing platform.
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.
