FAQ

Do I need to install drivers or software?

No. All tools run directly in your browser using standard web APIs. No downloads, extensions, or admin rights are required.

Can these tools replace manufacturer software?

For quick diagnostics and verification they work well. For advanced configuration like custom DPI curves or RGB lighting you still need the manufacturer app.
