Fake User-Agent Generator

Summary

This tool generates syntactically correct, realistic user-agent strings for all major desktop and mobile browsers. All generation runs entirely in your browser — no data is sent anywhere. Use the filter controls to target specific browsers and platforms, then generate one or hundreds of UAs at once.

How it works

1. Select the browser type (Chrome, Firefox, Safari, Edge, or Any) and platform (Desktop, Mobile, or Any).
2. Choose how many user-agent strings to generate (1 to 100).
3. Click "Generate" to produce the list instantly in your browser.
4. Click any individual UA to copy it, or use "Copy All" to grab the full list.
5. Use "Download .txt" to save the generated strings to a plain-text file.

Use cases

• Test how web scrapers or crawlers handle different browser identities.
• Check server-side user-agent parsing and detection logic.
• Simulate mobile vs. desktop traffic in automated test suites.
• Fill dummy data fields in QA or staging environments.
• Benchmark CDN and WAF rules that branch on User-Agent headers.
• Populate sample datasets for analytics or machine-learning experiments.
• Verify that A/B tests correctly segment by browser type.
• Demonstrate user-agent spoofing risks in security training sessions.
