About User-Agent Parser
This page parses browser, OS, device category, and version data from an HTTP User-Agent string. Paste a UA from a log or request header to view fields using common recognition rules.
A UA is client-supplied and can be spoofed or changed by browser policies. It is useful for diagnostics and analytics, not as the sole basis for authentication or security decisions.
How User-Agent Parser works
UA strings concatenate multiple product tokens, making a log line difficult to interpret at a glance. The page separates common fields so an error report and request record can be compared quickly.
Browsers are reducing UA detail, and Client Hints may provide more accurate data. For reliable feature decisions, test the actual API instead of inferring capability from a UA.
