Download websites that use Planet

Planet is a name that more than one product answers to, and pretending otherwise would make this page useless. The website recorded against our entry belongs to a long running open source feed aggregator, while unrelated companies in satellite imagery and in marketing analytics trade under the same word. What we count is a fingerprint match. We see a pattern in a page, we label it Planet, and the label means the signature was present, not that the domain is a customer of any particular company.

As of October 2026 the signature appears on 316 sites, and version strings are readable on part of that footprint. We hold 2 distinct version values, and the one our summary carries as representative is 2.0. A version vocabulary that narrow usually means either that the code is stable rather than actively developed, or that only some deployments announce a version at all. No vendor, licence or implementation language is recorded against this entry, which is itself informative, since a commercial product with a marketing site behind it normally leaves those fields filled.

Taken as the aggregator, the technology points at a particular kind of site. A page that gathers other people's feeds into a single stream is usually maintained by a community, a project or a department rather than by a company, and pages like that are quiet, long lived and rarely rebuilt. Our catalogue files the entry under Feed readers because a feed assembler is not quite a content management system and not quite anything else.

An ambiguous name is exactly the case where a full list beats a lookup. Checking a single domain returns a label you have no way to audit. Downloading the set lets you look at the domains together, see what kind of sites they really are, and decide for yourself which product the signature describes, and if the answer splits into groups then you can split the list on your own terms. We would rather hand over the evidence with the caveat attached than publish a clean sentence we cannot defend.
