User Agent Parser
Parse and identify browser, OS, and device from any User-Agent string instantly.
A modern Chrome user agent string still contains the word Mozilla and a fake reference to Safari and AppleWebKit, leftover compatibility cruft from decades of browsers pretending to be each other so older sites wouldn't block them. Reading one by eye to figure out what actually sent a request means untangling that history first, which is exactly what this tool automates: paste in a User-Agent string and get back the actual browser name and version, the operating system, and whether the request came from a phone, tablet, or desktop, stripped of all the historical noise.
