Diff Checker is a web-based application that helps developers quickly identify differences between two files. It can compare text, files, and even directories, and generate an overview of the differences. It displays the results in an easy-to-read format and highlights the differences in color. It also allows users to manually select the differences they would like to review. This helps developers quickly identify bugs and quickly makes changes to code. Diff Checker can also be used to compare different versions of a program or to compare a program against a previous version.
