Devtool Jail is a powerful anti-null and anti-inspect security addon for CodyChat that protects your source code by detecting and blocking users who attempt to open developer tools or inspect elements. Once triggered, it automatically jails offenders after a set number of attempts, with customizable jail duration and exemption ranks so the owner or trusted staff can still debug safely. It also includes an optional right-click block for stricter protection and detailed logs showing jailed users, their attempts, and timestamps. Fully translated and available in English, Arabic, Bulgarian, Croatian, French, German, Greek, Dutch, Portuguese, Romanian, Russian, Spanish, and Turkish.
