Compare text with a free diff checker
Use a text diff checker for code changes, document revisions, config files, release notes, or any two line-based text blocks. The output makes additions and removals easy to scan.
Line-based and browser-only
This lightweight diff compares lines and keeps the original inputs on your device. It is intentionally simple and quick for everyday comparisons.
How large can the comparison be?
For a responsive browser experience, each side is limited to about 1,200 lines.
