User Agent Parser
Parse and extract information from user agents
Frequently asked questions
What is a User-Agent string?
A User-Agent string is a text identifier sent by your browser (or any HTTP client) with every request. It tells the server what browser, operating system, and device you're using — for example, Mozilla/5.0 (Windows NT 10.0; Win64; x64) Chrome/120.0.
How does the User-Agent Parser work?
This tool uses the ua-parser-js library to parse user-agent strings. It extracts the browser name and version, rendering engine, operating system, device type, vendor, and CPU architecture from the string.
Can I parse a user-agent from another device?
Yes! Simply paste any user-agent string into the input field. You can find user-agent strings in HTTP request headers, server logs, or analytics tools. Use the Share button to send a parsed result to someone else.
What does 'My User Agent' do?
Clicking My User Agent automatically fills in the user-agent string from your current browser. This is a quick way to see what is your agent or the information your browser is sending to websites you visit.
