A diff checker highlights the differences between two pieces of text, making it easy to see what was added, removed, or changed. This is essential for code reviews, comparing configuration files, checking document revisions, and verifying database migrations.
The tool performs a line-by-line comparison and color-codes the results: green for additions, red for removals, and yellow for modified lines. Line numbers are included for easy reference. You can switch between an inline unified view and a side-by-side split view depending on your preference.
Statistics show the total number of added, removed, and unchanged lines, giving you a quick summary of how much changed between the two versions. All comparison happens in your browser with no data sent to any server.
