Choose a browser
Pick a specific browser or leave it on random when you want varied output.
Generate fake useragent
Generate user-agent strings for different browsers and test rendering without manually hunting examples. Use the controls in the form to tune the result before each run. On pages that support count, generate several options at once and compare them side by side. Keep the outputs that fit best, then copy or download them for QA, mockups, demos, or internal documentation.
Mozilla/5.0 (Windows NT 5.0) AppleWebKit/5342 (KHTML, like Gecko) Chrome/40.0.814.0 Mobile Safari/5342
This user-agent string is generated for the selected browser.
The user-agent generator builds browser strings from the browser and count you choose.
Set the count
Choose how many user-agent strings you want to generate in one run.
Generate results
Run the generator to get one string or a short list of browser-specific user-agent examples.
Reuse the output
Copy or download the best results and reuse them in QA flows, demos, test fixtures, and mockups.
A simple sample shows how the user-agent generator can produce realistic browser strings for testing and product work.
Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/123.0 Safari/537.36
This type of result works well for browser testing, support flows, QA notes, seeded data, and product demos when you need believable user-agent strings fast.
The user-agent generator is useful in several practical product, QA, and support scenarios:
Fill logs, tables, and admin screens with realistic browser strings for demos and internal tools.
Generate browser-specific examples for QA checks, support docs, and validation flows.
Create multiple user-agent strings at once for fixtures, seed data, and product mockups.
Compare how browser-specific strings look in dashboards, audit trails, and technical UI states.
A few practical ways to get better results from the user-agent generator:
Choose a specific browser when you need predictable output for targeted testing or screenshots.
Use random mode when you want broader variation for tables, fixtures, and bulk examples.
Generate several results at once when you need data for admin panels, logs, or QA scenarios.
Copy or download useful results when you want to reuse the same shortlist across tests and product notes.
Answers to common questions about how the user-agent generator works and where it is useful.
Can I generate several user-agent strings at once?
Yes. Use the count field to create several user-agent strings in one run, which is useful for fixtures, tables, logs, QA cases, and demos.
Can I choose a specific browser?
Yes. You can pick Chrome, Firefox, Safari, Opera, Internet Explorer, or leave the browser on random when you want mixed output.
Where can I use these user-agent strings?
They work well in QA workflows, product demos, admin panels, technical mockups, test datasets, and support documentation.
What should I do after generating a shortlist?
Keep the most useful results, then reuse them in your flows, fixtures, logs, screenshots, or internal documentation.
