纯前端运行不上传服务器，代码对比太安全了。
比对大文件很流畅，高亮很清晰。
重构代码的救星，秒出diff。
好用，比git diff看起来直观多了。
以下短评基于实时网页探查、定价机制与同类产品基准由 AI 综合模拟生成，旨在呈现不同使用场景下的常见槽点与亮点，非实名真实用户评价。
Read changes in two columns side by side, or switch to a single-column unified diff in the same format as git diff and patch files.
Darker highlights mark the exact words and characters that changed inside a modified line, not just the lines that differ.
The comparison runs entirely in your browser, so confidential code, contracts and config files never leave your device.
Ignore whitespace, indentation and capitalisation differences, and control how much unchanged context is shown around each change.
Compares plain-text files up to 50 MB in a background thread, so pages with hundreds of thousands of lines do not freeze the UI.
DiffDuo is a free online diff checker that compares two texts, files or code snippets directly in your browser. It shows removed lines in red, added lines in green and highlights the exact words that changed, in either a side-by-side split view or a git diff-style unified view.
Compare two versions of a source file in any language, spot the exact characters that changed, then copy the patch in diff format for your notes or issue tracker.
Find what changed between two JSON, XML, YAML, CSV or SQL files, such as two API responses or two database schemas.
Paste two drafts of an article, contract or translation to see every added, removed and rewritten word without installing desktop software.
Drop in two log files and highlight only the lines that changed between runs, with whitespace and case noise optionally ignored.
