Can I compare code in any programming language?

Yes — the diff is text-based, so it works on any language or plain text; it does not need to understand the language's syntax to compare it.

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

Comparison runs in your browser, so very large files (many thousands of lines) may render more slowly depending on your device, but there is no hard file-size cap.
