Vanilla software

Computer software, and sometimes also other computing-related systems like computer hardware or algorithms, are called vanilla when not customized from their original form, meaning that they are used without any customizations or updates applied to them. Vanilla software has become a widespread de facto industry standard, widely used by businesses and individuals. The term comes from the traditional standard flavor of ice cream, vanilla. According to Eric S. Raymond's The New Hacker's Dictionary, "vanilla" means more "default" than "ordinary".
