Pixelscan

What Pixelscan actually does

A consistency scanner rather than an attribute dump: it compares the story your IP tells with the story your timezone, locale and fingerprint tell, and reports where those three disagree.

What can and cannot be measured about Pixelscan

This entry has no repository, so none of the usual repository fields exist for it — no push date, no release tag, no archive flag, no licence identifier. Its state comes from one measurement only: the register requested the address and recorded what came back. Anything in the range 200 to 399 makes a non-repository entry ACTIVE, and that clause is the one the first edition of the rubric did not have at all, which is why live page entries carried no state under it.

Read that for exactly what it is. It says the thing is reachable. It does not say the page still works correctly, because no HTTP status can carry that. Where a stronger signal exists — a repository, a version, a dated revision — this register prefers it, and where one does not, it prints the weaker signal and names it as weak rather than dressing it up.

Where Pixelscan sits in this catalogue

Pixelscan is filed in section 03, detection test pages & fingerprint scanners, whose scope is this: Pages you point a browser at to see what it gives away. This section is where a link register earns its keep: test pages rot faster than repositories. An entry sits in exactly one section here. Where a project could defensibly go in two, it is placed where a reader would look for it first rather than where it fits most tidily, and that is an editorial decision rather than a measured one.

Filed beside it in the same section: AmIUnique (ACTIVE), bot.sannysoft (ACTIVE), IPHey (ACTIVE). Comparing an entry against its own section-mates is more informative than comparing it against the catalogue as a whole, because everything in a section is answering roughly the same question and the differences left over are the ones that matter.

There is no licence field, because there is no source to licence — this is a live page rather than a code repository. It is grouped instead with every other entry the rubric marks ACTIVE, which is the axis that actually distinguishes entries of this kind from one another.

Substitutes for the same job, with no claim that either is better: CreepJS (live). The alternative relation is symmetric and carries no ranking, because this register publishes no ranking of any kind. The full Pixelscan comparison table sets all of them side by side on licence, push date, release cadence and state.

What to settle before you adopt Pixelscan

Consistency checking is the class of test that catches a well-built fingerprint behind a badly-chosen proxy, which is why the pre-launch gate idea exists at all. Its scoring method is not published, so read the individual findings rather than the summary.
