Works great for

💻

Comparing code versions

Spot regressions between two versions of a function or config file without opening a full IDE. Word-level diff highlighting pinpoints exactly which characters changed inside each modified line.

✍️

Document draft review

Compare an original document draft against a revised version to see every addition and deletion at a glance. The unified and split view modes let writers and editors choose the layout that suits their workflow.

📋

CSV and data export audits

Paste two CSV exports taken at different times to find added, removed, or changed rows. The line-by-line diff makes it easy to audit data pipeline outputs and catch unexpected record changes.

🔧

Config file comparison

Compare nginx, Docker Compose, or Kubernetes YAML files before and after a change to catch unintended modifications. The copy-diff button exports a patch-style diff you can share with your team.

🌐

API response change tracking

Paste two JSON or XML API responses to find fields that were added, removed, or modified between releases. Useful for validating that a refactored endpoint still returns the expected structure.

📝

Pre-publish content audit

Verify that edited web copy, legal text, or email templates contain only the intended changes before going live. The additions and deletions counters give a quick summary of the scope of the edit.

Frequently asked questions

How do I compare two blocks of text for differences?

Paste the original text on one side and the modified text on the other, and the tool generates a line-by-line diff with additions, deletions, and unchanged lines color-coded immediately.

Can I diff code snippets, not just plain paragraphs?

Yes. The comparison works on any plain text, including source code, configuration files, or logs, since it compares line by line rather than requiring a specific file format.

Is there a size limit on the text I can compare?

There is no fixed limit for typical documents or code files. Very large files, tens of thousands of lines, may take longer to render but the comparison itself has no hard cutoff.

Does the diff checker show stats on how many lines changed?

Yes. Alongside the color-coded diff view, it displays summary stats for the number of additions and deletions, and you can copy the generated diff output directly.
