Why use an online diff?

Quickly spot changes between configs, JSON, SQL or code snippets without opening a full IDE. Processing stays on your device.

Is this a character-level diff?

It compares line by line (LCS). Ideal for configs and short code blocks.

Do you store my text?

No. Comparison runs only in the browser.
