What we measured while building a browser profile manager

Not what an antidetect browser promises - what Chromium, Edge, Firefox and the Android tools actually did on a Windows machine when we asked them to, including the several occasions on which they disagreed with their own documentation.

10 postsEach one names its data, its tool and its claimStart with what fingerprinting cannot do

By subject

Browse by what it is about

Every subject here holds more than one post. A tag with a single post on it is a page that exists to be crawled rather than read, and the suite fails when one appears.

The standard

What has to be true before a post goes up

Three rules. The first is applied by the build - a post that cannot name its source, its tool and its own claim fails the deploy - and the other two are kept by the person writing.

  • A measurement, or nothing

    Every post names the data it rests on and the tool that produced it, and both are printed at the bottom of the page. Where a number appears, the browser or tool version it came from appears beside it.

  • No claim the product cannot keep

    A browser that has not been patched at the source level is detectable through property-descriptor and prototype inspection. Nothing here will tell you otherwise, and the words this site refuses to use are listed in the documentation.

  • Published in tranches, not in a batch

    The plan runs to a hundred posts. They go out a handful at a time, each one able to stand on its own findings, because a hundred pages appearing at once is a pattern search engines have a name for and readers can feel.

The software all of this was measured on

Ward runs many browser profiles on one PC, each with its own proxy and its own device identity. The free plan needs a free account and no card, and there is nothing to buy today.
