About this tool
Browser, OS, and engine are identified from the User-Agent string using the same kind of pattern matching most sites use, refined with the newer navigator.userAgentData Client Hints API where the browser supports it (currently Chromium-based browsers). Both approaches describe what the browser chooses to report, not a verified fact — any of it can be changed by browser settings, extensions, or developer tools, so treat this as informational rather than authoritative.
Everything else — screen size, language, timezone, touch support, CPU core count — comes directly from standard browser APIs (navigator, screen, Intl) with no parsing involved. Nothing detected here is sent anywhere; it's read and displayed entirely within your own browser tab.
