ตัวแยกวิเคราะห์ User Agent

คำถามที่พบบ่อย

Quick answers.

›What information is in a user agent?

It typically identifies the browser name and version, the host operating system, and the layout engine like `Blink` or `WebKit`. Mobile strings also include specific device models.

›Is the parsing done on a server?

No. The logic runs in your browser using local JavaScript, meaning your identifier is never logged or stored on our infrastructure.

›Why do many strings look like 'Mozilla/5.0'?

This is a legacy convention from the early web. Most modern browsers include it for backward compatibility with older servers that search for that specific prefix.

›Can I check my own user agent?

Yes. Upon loading, the tool automatically detects and parses the string your current browser is broadcasting to websites.
