Are these generated user agents a live feed of the latest browsers?

No. This generator builds syntactically valid strings from browser-specific templates that are useful for QA, parser testing, demos, and documentation.

Can I export the generated list?

Yes. You can copy the generated list or download it as TXT or CSV.

Should I use these strings for production security rules?

No. They are best used for testing, mock data, import fixtures, and examples. They should not be your only source for security or fraud decisions.

Sample data for QA and parser tests

Generate bulk user agent strings

Build a filtered list of syntactically valid user agents from browser-specific templates. The goal here is practical test data that respects current UA reduction rules and real browser families.

How many rows do you need?

Device types

Desktop Mobile Tablet

Browser families

Chrome Firefox Safari Edge

Chromium-based mobile rows intentionally use reduced tokens such as Android 10; K, and Safari rows intentionally keep frozen OS tokens. That is expected browser behavior, not a bug in the generator.

Best use cases

Parser unit tests, import fixtures, allowlist demos, browser-specific screenshots, and synthetic QA scenarios.

What not to use it for

Production security rules, fraud scoring, or anything that requires real user telemetry and high-confidence detection.

Need the live value instead?

Use the checker page if you want to see what your current browser session exposes right now.

Why do some Chrome or Safari rows look frozen?

Modern Chromium browsers reduce parts of the UA string for privacy, and Safari now freezes OS tokens on more platforms. So values like Android 10; K or Mac OS X 10_15_7 can still be correct for current browsers.

Can I generate more than one browser family at a time?

Yes. Keep several browser and device checkboxes enabled and the tool will balance the list across the compatible browser and device groups you selected.

Can I copy the list into a spreadsheet or test fixture?

Yes. Use Copy for newline-separated strings or export as CSV for spreadsheet-friendly results.
