Mruby asigur\u0103 compatibilitatea sintaxei la nivelul Ruby 1.9, dar suport\u0103, de asemenea, caracteristici separate din versiunile mai noi. Interpretul se remarc\u0103 printr-o consum redus de memorie \u0219i capacitatea de a fi \u00eencorporat \u00een alte aplica\u021bii. \u00cen plus, este suportat\u0103 compilarea programelor Ruby \u00een bytecode cu ajutorul compilatorului dezvoltat de proiectul &#171;mrbc&#187;.
