Online Text Diff Checker

Compare two texts side by side and highlight differences instantly.

Runs in your browser — nothing is uploaded.

How to use this tool

1. Paste the original text on the left and the new text on the right.
2. Added and removed tokens highlight as you type — no submit button.
3. Use the difference count to sanity-check a config or snippet before you commit.

Good to know

• This is a line-oriented checker for snippets and configs, not a git merge tool.
• Minify JSON first if whitespace-only noise is drowning the real change.

Comparison stays in the browser, so you can paste staging payloads without sending them to a third-party diff site.
