Generate Random User Agent

Free Random User Agent Generator

This tool allows you to generate random user-agent strings like Mozilla/5.0 (compatible; MSIE 8.0; Windows NT 5.3; Trident/5.1) or Opera/14.30 (Windows NT 5.3; U; KW) Presto/2.9.164 Version/10.00. These strings replicate various browser and operating system combinations, making them ideal for form validation, mock data, headers testing, or analytics simulations.

You can generate up to 1000 random user-agent strings with a single click. Each string mimics a real browser's format, including details such as the browser engine, version, platform, and operating system identifiers.

The user-agents are randomly generated to resemble different browsers like Chrome, Firefox, Safari, Edge, Opera, and Internet Explorer, across various versions and platforms. This provides a diverse dataset useful for simulating traffic, testing device detection logic, or managing request headers in development environments.

All results can be downloaded as a CSV or Excel file, making it simple to import them into scripts, test plans, or development tools.

This tool is completely free to use, with no sign-up required. Generate your random browser user-agent strings quickly and use them in any testing or development workflow.
