Find answers to common questions about Quick Differ, privacy guarantees, and supported language features.
Quick Differ is a free, browser-based tool that allows developers to quickly compare code snippets side-by-side and highlight changes for debugging, learning, and reviewing.
Yes! The tool is 100% free to use, with no account or subscription required. We sustain development through non-intrusive ads.
No account or registration is needed. Just open the site and start comparing code immediately.
No. We do not store, log, or send your code to any server. All processing happens in your browser (client-side) for complete privacy.
Absolutely. You can compare any plain text — JSON, logs, CSVs, documentation, etc.
We support all major languages including JavaScript, Python, Java, C++, HTML, CSS, and more. Syntax highlighting and diff logic are language-agnostic.
We’re exploring Git or GitHub integration as a future enhancement. Let us know if that’s something you’d like to see!
Currently, sharing comparisons via URL is under development. Until then, you can copy and paste your results manually.
Ads help us cover hosting, development, and maintenance costs. We aim to keep them minimal and non-disruptive.
You can support us by sharing the tool, giving feedback, or starring the project on GitHub once it’s public. A “Buy Me a Coffee” option is also coming soon!
Yes. Quick Differ is responsive and works on all modern browsers across devices — desktops, tablets, and smartphones.
