Can I use this tool for source code diffs?

Yes. The diff checker works seamlessly on Python, JavaScript, CSS, HTML, SQL, and plain text files.

Is there a limit on how much text I can compare?

Because processing executes client-side using an optimized diff algorithm, you can compare documents with thousands of lines instantaneously.

Are my comparisons saved anywhere?

No. Everything is stored strictly in your browser's temporary memory and is erased as soon as you close or refresh the tab.
