About This Tool

This free online user-agent parser helps you quickly classify incoming user-agent strings during QA, support, and analytics troubleshooting. It extracts browser family, operating system, device type, and rendering engine into a clean readable output.

All parsing happens in-browser, and no user-agent data is stored on IO Tools servers.
