A QUICK WALKTHROUGH
How to use this tool
- Choose a platform and browser family.
- Generate one or more synthetic strings.
- Copy the result for use in a test environment.
Synthetic test data only
This tool generates bounded, clearly synthetic strings. It does not claim to represent current real browser releases and does not read or alter your browser User-Agent.
Local generation
Generation uses browser randomness and stays on this device. No request, tracking database, or remote catalog is used.
GOOD TO KNOW
Common questions
Are these real current browser User-Agents?
No. They are synthetic test strings from a finite template set.
Does this change my browser identity?
No. It only displays and copies text for testing.
