A system, method, and non-transitory computer-readable storage medium for identifying customization changes have been disclosed. The system comprises a processor and a memory that includes instructions executable by the processor to cause the system to identify a baseline script of a plurality of baseline scripts from a baseline instance that corresponds to a custom script of a plurality of custom scripts from a customized instance. The customized instance is a customized version of the baseline instance. The instructions are executable to cause the system to compare the baseline script to the custom script to identify one or more changes between the baseline script and the custom script, to determine an amount of change using the one or more identified changes, and to generate a graphical user interface that includes an identifier of the baseline script, an identifier of the custom script, and a graphical indication of the amount of change.
