Why the ranking looks this way
Products appear in Harpd Rank order. The developers filter is derived from each product's own declared product type and capability tags; Harpd does not infer suitability from anything else. Approved products enter free; optional Credits add permanent Rank Points, which are promotional placement rather than an editorial recommendation.
