Rich Diff Checker - A Smarter Way to Diff

The state of modern diff tools has evolved to provide just slight variations of the traditional binary diffs (added/deleted), to the point where it's hard to imagine a better alternative could exist.

With 5 years of R&D behind it, Commit Cruncher powers a next-generation diff checker designed for developers who need to review code faster, without compromising quality.

Diff Checker Features

Text Compare and Code Compare with Rich Diff

The Rich Diff Checker finds the true differences between any two text files or code files by classifying changes using the full set of operations that developers recognize:

Diff Operation	Definition	Examples
Addition	Brand new lines that are distinct, excluding lines that change an existing line (labeled "Updates").
Deletion	Lines that are completely removed from the file.
Update	An existing line that was partly changed or tweaked.
Move	A line that is cut and pasted to a different location.
Copy/Paste	Identical line contents that are pasted to multiple locations across one or more files.
Find/Replace	A pattern of change where the same string is removed from 3+ locations and substituted with consistent replacement content.

Code Syntax Support

Select a code language from the dropdown to get custom syntax highlighting and autocomplete to navigate your code just like in your own IDE.

Rich Diff Operation Summary

See how lines changed before even reviewing them. Every change operation is aggregated in the file header.

Keep your code DRY: Using the Rich Diff Checker, you can visually grasp the extent of the duplication introduced by your changes. Keep an eye out for the Copy/Paste and Find/Replace operations that slowly but surely chip away at the maintainability of your code.

Focus on what's important

The Rich Diff Checker shows a condensed view of the diffs, directing your attention to what's actually been changed.

Need full context? Simply expand the unchanged lines.

Rich Diff Checker shows only changed lines, hiding collapsing unchaged lines

Same Diff in GitClear

GitClear's code review tools are designed to fill the gaps left by traditional review platforms to allow you to focus on what's important. By weaving together commits and translating lines of code you get a pull request with 30% fewer lines of code to review.

And there's more. We've built additional features to make your developer experience even better:

🤖 AI summaries and completions

Get a quick snapshot of what's changed; understand updates and their context in seconds.
🎯 Targets and Goals for Pull Requests

Set clear standards for PR size, tests, review duration, and delivery time so everyone knows what success looks like.
⏳ Review only what's new

By default, GitClear shows only the changes you haven't seen since your last visit, so you never waste time reviewing the same lines twice.
