What is my user agent?
Your user agent and Client Hints right now, plus a parser for any UA string: browser, version, OS, device, engine and bots.
Your user agent
Client Hints
Chrome, Edge, Opera and other Chromium browsers send precise details — OS version, model, architecture — not in the User-Agent string but via Client Hints: short Sec-CH-UA headers and the navigator.userAgentData JavaScript API.
Datos clave
A User-Agent is the string in which a browser tells a site who it is. Open the page and you immediately see your own string and its breakdown. Chrome has “frozen” this string: it no longer shows the real Windows version or device model, which only Client Hints provide, and we show those too (in Chromium). You can paste any other string to parse.

- Procesamiento
- Partly on our server: our server sees and parses the User-Agent string and Client Hints headers (they arrive with every request anyway), while the browser reads navigator.userAgentData
- Entrada
- Nothing to enter (your own User-Agent is shown) or a pasted User-Agent string
- Límites
- No sign-up and no limits; a string from the ?ua= link is parsed like a pasted one; Client Hints values are available only in Chromium
- Resultado
- Your User-Agent, its breakdown (browser and version, OS, device, engine, bot), Sec-CH-UA* headers, high-entropy values, notes on frozen fields and a shareable link

What is a user agent and how to find yours
A user agent is the string your browser sends to every website: its name and version, operating system and device type. This page shows your user agent as soon as it opens, parses it, and lists Client Hints — the precise details Chrome no longer puts in the string.
Cómo usar
- Open the page — your user agent and its breakdown appear right away
- Check the Client Hints block if you use a Chromium browser
- To parse another string (e.g. from server logs), paste it and click “Parse”

Desplaza la tabla hacia los lados
Dónde somos más débiles: the rules are our own, so rare devices and clients may not be recognised, and a claimed bot cannot be treated as confirmed without an IP check.
Cuándo elegir PromoPilot: When you need your own User-Agent fast, to decode a string from logs or to check which bot a request claimed to be. The parser uses its own rules and does not replace full device databases.
