Frequently asked questions
Do unused imports slow code down?
They add load time in Python and bundle size in JavaScript, and they make dependencies harder to understand. Go refuses to compile them.
Is the Unused Imports Finder free?
Yes. It is free with no sign-up, and it runs entirely in your browser, so your input is never uploaded or stored.
How accurate is a browser-based code check?
It uses fast heuristics on the snippet you paste, so it is great for quick feedback. For whole repositories, cross-file analysis and history, run a full CodeInspector scan.
