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 move quickly through code, without compromising quality.

More operations:
- Truer diffs: The rich diff cuts down the noise to reveal only what's actually changed. End Result? 30% fewer lines of code (research).
- Universal application: Works for any type of code language (file type) and has extensive syntax support for 40+ languages.
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.

Streamline Your Pull Request Reviews
The Rich Diff algorithm delivers its full potential when applied to a codebase. GitClear's code review tools are designed to fill the gaps left by traditional review platforms.


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
See changes distilled at a glance to speed up understanding and glean immediate context.
-
🎯 Targets and Goals for Pull Requests
From Diff Delta limits (enforcing smaller PRs) to goals for review and delivery time.
-
⏳ Never re-review changes unnecessarily
By default, GitClear only presents the changes to each file since you last saw it.
