Pretty Diff
Pretty Diff is a language-aware code comparison tool, beautifier, minifier, and parser for a variety of languages. Pretty Diff was created to compare code samples for various languages regardless of differences in comments, white space, and other factors. Currently, the project operates by beautifying code and then comparing the beautified product of the code samples. The goal in a future version is to introduce the comparison step directly into the beautifiers between the parse step and the beautification step to become a truly language-aware code comparison and analysis tool. The code comparison mode is the default mode and the only mode to require two code samples. Pretty Diff has progressively moved from community-driven dependencies to custom parsers to accomplish code beautification for a diversity of features and requests. Each of Pretty Diff's beautification libraries has a minify feature.

NextDiff
NextDiff is a free Windows utility for comparing files and folders in a clear visual interface. It helps users inspect differences between two versions of a text file, source code file, log, script, or configuration file. The side-by-side comparison view highlights added, removed, and changed lines, while in-line change marking helps identify the exact modified fragments. NextDiff also supports folder comparison, direct editing, copy-left/copy-right merge actions, difference navigation, and flexible options for ignoring case, blank lines, and whitespace. It is a useful freeware tool for developers, administrators, writers, and anyone who regularly works with changed files.
