How to use Generate Random User Agents
- 1. Set how many user agents to generate. Enter How many user agents to control the batch size, each one a plausible browser user agent string spanning different browsers and operating systems.
- 2. Choose a separator. Set Separator to a newline or comma depending on whether you want each string on its own line or joined into a single delimited list.
- 3. Copy the generated user agents. Copy the strings from the output pane and paste them into a test suite header, a web server log sample, or an analytics dashboard mock.
When to use Generate Random User Agents
Generate Random User Agents produces browser user agent strings covering different browsers, versions, and operating systems, useful whenever code that parses or filters by user agent needs varied test input without capturing real visitor headers.
- Testing a browser detection function. You wrote code that parses the user agent header to determine browser and OS, and want a batch of varied strings to confirm the detection logic handles Chrome, Firefox, and Safari correctly.
- Simulating web server access logs. You are testing a log analytics tool that reports on visitor browsers, and generating varied user agent strings gives you realistic-looking sample log entries to test the reporting.
- Mocking request headers in an API test. You are writing integration tests for an endpoint that behaves differently based on the client's user agent, and generated strings let you set that header to different values across test cases.
- Populating a device analytics dashboard demo. A dashboard demo shows a breakdown of visitor browsers and operating systems. Generating a batch of user agents gives you sample data to populate the chart before real traffic arrives.

About the Generate Random User Agents tool
Generate Random User Agents runs as plain JavaScript in your browser tab, with no server behind it. Generate random browser user agent strings. Whatever you put in stays on your device from start to finish.
The tool is part of EditSafely's Random Tools section, 120 single-purpose utilities built around the same idea: open the page, get the result, keep your data to yourself.
You can shape the output with 2 settings, including How many user agents and Separator, and the result refreshes the moment you change one. A worked example further down the page shows exactly what the tool produces for a real input.
That local-first design has practical benefits beyond privacy. The tool keeps working on a flaky connection once the page has loaded, results are instant because nothing round-trips to a server, and it is safe to use with confidential material.
Frequently asked questions
Is Generate Random User Agents free to use?
Yes, it is completely free. All 2,658 tools on EditSafely work without an account, a subscription or usage limits.
Does the generator send anything to a server?

How do I get a different result?
Run the generator again. Each run is computed fresh on your device, and any options you change are applied to the next result immediately.
Do I need to sign up or install anything?
No. The tool works in any modern browser on desktop, tablet or phone. There is no account to create, no extension to add and no software to install.
How do I use the result?
The output panel has a one-click copy button, and you can keep refining the input while you work; the result updates in place as you type.
