Random User Agent Generator

 
Mock fixture data generated locally in your browser with the Web Crypto API.

Browser fixture strings

Generate realistic-looking desktop and mobile browser user agent strings for analytics demos, log fixtures, QA data, and mock API payloads. These values are fictional examples, not real visitor identities or market-share samples.

How it works

  1. Your browser draws random values from the Web Crypto API
  2. One desktop or mobile browser template is selected
  3. OS, device, browser, and version parts are combined locally
  4. The generated mock user agent can be copied as-is
