Download websites that use Rain

Rain is one of the harder entries in our catalogue to write about honestly, and the reason is the name itself. A short common word gets reused across unrelated projects, and a fingerprint built around a generic marker is more likely to collide than a fingerprint for a product with a distinctive asset path. We file the entry under Ecommerce with PHP recorded as the implementation language, while the only address we hold for it points at a retail point of sale platform sold by subscription, a combination that already shows how loosely the label sits.

So the row is best understood as a detection bucket rather than as a single well defined product. As of October 2026 the marker appears on 3,140 sites. The population is real in the sense that something consistent was matched in the page source of each one. What the population is not is a guaranteed count of installations of one product from one vendor, because we hold no vendor and no first release year for this entry, and without either of those the identity stays thinner than we would like. The licence field on the row reads Proprietary, and the site at the address we hold sells a hosted product rather than publishing source, so that field is no evidence about how the matched code is distributed.

Used carefully, the list still has a job. If you sell or maintain something that answers to this name, our export is the closest thing available to a public user list, and inspecting a sample of the domains will tell you quickly whether the marker is catching your users or somebody else's. If you are researching stack composition, the co present technologies on each row carry more information than the label does, because they show what kind of site the marker actually appears on. Anyone building a prospect list from a name this generic should validate a sample before spending money on the rest, which is advice we would rather give than let a clean looking figure be trusted more than it deserves.
