What is Diff Checker?
Diff Checker compares two snippets of text, source code, JSON or full files and highlights every change side-by-side. Everything runs locally inside the browser extension—no data ever leaves the user’s machine—so it suits security-sensitive workflows. Developers use it for quick code reviews, writers for document edits, testers for config and log diffs. Supports file upload, tab-to-tab diff, multiple encodings, and options to ignore case or whitespace.
