What is a User Agent Parser?
A user agent parser breaks down the browser, operating system, device type, and engine from a UA string. Mobile QA teams use it to reproduce bugs reported from specific devices and to verify responsive behavior assumptions.
How to use it
Paste any user agent string or click Use my browser UA to inspect your current session. The parser highlights mobile, tablet, and bot signals so you can route issues to the right test matrix entry.
Mobile QA use cases
Reproduce customer bugs when only the UA string is available in support tickets. Validate that your app serves the correct experience for iOS vs Android WebViews. Check whether traffic is coming from emulators, real devices, or crawlers. Document device context in bug reports alongside screen size references.
Related tools
Cross-check parsed device classes against Mobile Device Sizes, then use the cURL Builder or Postman to cURL tools when reproducing API calls from the same client context.
