About User Agent Parser
User Agent Parser uses a short set of regular-expression checks to label common Chrome, Edge, Firefox and Safari strings plus broad operating-system, device and engine families. Use it for a quick human-readable note while debugging a reported browser string. For example, an Android string containing Mobile is labeled Android and mobile. The parser is not a maintained user-agent database and can misclassify bots, Chromium variants, iPad desktop-mode strings, spoofed agents and future versions. Parsing is browser-local; never use the result for security, authentication or permanent feature decisions.
