Frequently asked

Is this accurate for every browser?

It handles the top ~95% of real-world UAs (Chrome, Safari, Firefox, Edge, Opera, Brave, Vivaldi, IE) on all major OSes. Edge cases and obscure browsers may report as "Unknown".

Why does my "Chrome" browser show as Blink engine?

Blink is the rendering engine Chrome uses (forked from WebKit in 2013). Edge and Opera also use Blink now.

Is UA sniffing a good idea?

No — feature detection is almost always better. Use this tool for debugging and analytics, not runtime branching.
