How User Agent Parser works

  1. By default, the tool automatically fetches and parses your current browser's active User Agent on page load.
  2. Type or paste any custom User Agent string into the input text area to analyze other devices.
  3. Click **Parse String** — the tool will inspect the token headers matching standard client indicators like `Windows`, `Macintosh`, `Android`, `Chrome`, `Firefox`, `Safari` etc.
  4. It cleanly extracts versions and renders descriptive results for debugging browser headers.
