Decode any User-Agent string into browser, OS, engine, and device.
Paste any User-Agent string (or load your own browser's) and instantly break it down: browser name and version, rendering engine, operating system, device type, and bot detection. Great for debugging analytics, server logs, and feature-detection issues. Includes ready-made example UA strings. Runs entirely in your browser.
This tool provides an instant breakdown of any User-Agent string directly in your browser without requiring installation or account signups. It accurately parses browser details, operating systems, device types, and bot detection flags, making it ideal for troubleshooting server logs and analytics data.
Good to know: For automated, large-scale log analysis or backend integration, a dedicated programmatic library or server-side package may be more suitable than a manual browser-based tool.
