Une collection de plugins est fournie pour int\u00e9grer cppcheck avec divers syst\u00e8mes de d\u00e9veloppement, d'int\u00e9gration continue et de tests, ainsi que des fonctionnalit\u00e9s telles que la v\u00e9rification de la conformit\u00e9 du code au style de codage. Pour l'analyse du code, il est possible d'utiliser \u00e0 la fois un parseur interne et un parseur externe de Clang.
