Frequently asked questions about User-Agent Parser
It's a line of text every browser and HTTP client sends with each request to identify itself: naming the browser, its version, the operating system and the rendering engine. Servers and analytics tools read it to tailor responses and to understand their traffic. The format is famously messy for historical reasons, which is exactly why a parser is useful for reading one at a glance.
It reliably identifies the mainstream browsers, engines, platforms and device types that make up the overwhelming majority of real traffic, and flags common bots and crawlers. User-agent strings can be freely spoofed and obscure or brand-new clients may not be recognised, so treat the result as a strong indication rather than proof, and note that modern browsers are deliberately reducing the detail they expose.
No. The parsing happens entirely in your browser with no network request: the string you paste, including your own user-agent when you use that button, never leaves your device. As an EU-built provider, Uptimeify keeps tools like this client-side wherever possible so there's nothing to transmit, log or store.
