What is Duplicate Code Finder?

Free — no account needed

Duplicate Code Finder is one of our GitHub Tools. Scan GitHub repositories for duplicate code blocks across multiple source files. Find refactoring opportunities. Paste your input, get the parsed or generated output instantly, and copy it straight into your project. It runs entirely in your browser, so nothing is uploaded and no account is needed.

Frequently Asked Questions

Is Duplicate Code Finder free?

Yes. Duplicate Code Finder runs in your browser and is free to use, with no account, no watermark, and no usage cap.

Do I need to create an account?

No. Open the page and use it. An account only becomes useful if you want to save tools to your own toolbox.

What happens to my data?

Duplicate Code Finder does its work on your own device. Your input is never uploaded to us, which is why it also works with sensitive material.

Does it validate my input?

Yes. Malformed input is reported with the position and the reason, so you can fix the source rather than guess.

Do I need to install anything?

No. Duplicate Code Finder runs in the browser on desktop, tablet, and phone. There is nothing to download and nothing to keep updated.
