About Recope

A small identity bureau, not a black box.

Most user agent generators do one job well — assemble a string — and stop there. They'll happily hand you "Safari on Windows," a combination that hasn't existed in the real world for over a decade, with the same confidence as "Chrome on Windows," which is one of the most common combinations on the internet. Both look equally valid on the page. Only one actually blends in.

Recope generates the string the same way any generator does, but it also tells you how plausible the combination is — whether it reads as ordinary traffic or as something a server-side check would flag immediately. That's the whole idea behind the "cover strength" rating on every result.

What it's for

Developers testing how a responsive layout behaves across browsers without owning every device. QA checking that a site degrades sensibly on older browser versions. Anyone who needs a properly formatted user agent string for a script, a header, or a debugging session, without digging through forum posts to find one.

What it isn't

It isn't a tool for evading detection or misrepresenting who's accessing a service — see the disclaimer for the specifics. A user agent string is one small signal among many a website can check, and treating it as a disguise on its own is a mistake we write about directly in the journal.

How it works

Every string is assembled in your own browser, from a set of realistic version and platform templates — nothing is generated on our server, logged, or stored. Full details are in the privacy policy.
