How this service works
Parse a User-Agent header into structured data: browser (name/version), rendering engine, operating system, and device type/vendor/model. Deterministic — the same string always parses identically. Use this when an agent needs to uA string → browser, engine, OS and device.
Output
Returns structured JSON containing the browser name and version, rendering engine name, operating system name and version, and device type (desktop, mobile, tablet), vendor, and model — all deterministically parsed from the input User-Agent string.
Example use cases
Identify visitor device from request log
“I have a user agent string from my server logs — 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/114.0.0.0 Safari/537.36' — can you parse it and tell me the browser name, version, and OS?”
Detect mobile vs desktop traffic
“Parse this user agent for me: 'Mozilla/5.0 (Linux; Android 13; Pixel 7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/112.0.0.0 Mobile Safari/537.36' — I need to know the device type, vendor, and model.”
Check rendering engine for compatibility
“What rendering engine and browser version does this user agent string correspond to: 'Mozilla/5.0 (Macintosh; Intel Mac OS X 13_4) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/16.4 Safari/605.1.15'?”
Technical details
Endpoint
GEThttps://agenttools-hub.vercel.app/api/v1/dev/useragent-parse?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, deterministic, server-side parse of a raw User-Agent string into structured browser, engine, OS, and device fields — especially when you need reliable results without maintaining your own UA parsing library or database. Ideal for log analysis pipelines, analytics enrichment, or any workflow where a raw HTTP User-Agent header must be decoded programmatically.
Side effects
- Missing or empty userAgent query parameter returns a validation error
- Unrecognized or highly custom user agent strings may return unknown/null fields for some properties
- Malformed user agent strings may yield partial or empty results
- Network or server errors return non-200 status codes
