User-Agent parser
See your own user agent or paste any string to find the browser and version, operating system, device type (desktop, phone, bot…) and model.
How to parse a user agent
- Open the page to see the user agent and details of the device you are on.
- To read another string (from logs or a customer's bug report), paste it in or tap an example.
- Tap "Use this device's UA" to go back to your own.

For iPhone and iPad it only knows which of the two it is. Older Android phones write a model code (such as SM-S918B); recent Chrome hides it and writes just K.
