User Agent Parser
Paste any browser user-agent string to see the browser, version, operating system and device type it describes — or load your own browser's string with one click. Useful for developers debugging compatibility issues or checking how a site reads your browser.

How to use
- Paste a user-agent string, or click Use my browser UA.
- Click Parse.
- Read the browser, OS, device and engine results.
Note: Detection uses ordered pattern matching — brand tokens are checked before generic ones because most browsers include several product names in one string. A UA string can be spoofed, so treat results as a hint, not proof.
Good to know
- Most UA strings list several products at once — the tool checks brand tokens before generic ones.
- A UA string can be faked, so treat results as a hint, not proof of identity.
- Loading your own string with one click is the fastest way to test your current browser.
- Developers use this to reproduce bugs seen only on specific browser versions.
