Comparing two versions of the same text is the whole job here. The Diff Checker takes two blocks -- files, config, query output, pasted logs -- and shows what moved, character by character, side by side or unified.

Diff Checker

Compare two text files.

When a diff is the right instrument

A diff is the fastest way to answer "what actually changed" when the change did not go through version control: a config file edited on a server, a CSV exported twice, a response body before and after a deploy, a document returned without track changes. The whitespace and case options matter more than they sound, because indentation churn and case-only edits are the two things that hide a real difference inside a wall of red.

Comparison runs in your browser, so the text never leaves your device. The result exports as a .patch for whoever has to apply the change, or as a shareable link when the argument is about which side is correct.

How to choose a Data tool

Choose the view by what you are trying to see.

Reviewing someone else's edit

Side by side, with whitespace shown. Seeing both originals is worth the horizontal space.

Confirming two files are identical

Unified view. A clean result is one empty panel instead of two full ones to read.

Handing the change to someone else

Export the .patch. It applies with git apply and needs no explanation.
