UserAgent Shifter is a developer and power user tool that modifies your browser's identification string. Switch between desktop, mobile, and tablet profiles to test responsive designs, access lighter mobile versions of websites for faster loading, and verify cross-platform compatibility. Ideal for web developers testing their sites, users on slower connections who prefer mobile layouts, and anyone needing to view alternative versions of web content. All processing happens locally with zero data collection.
