It's probably broader than Starfinder (I think I've experienced the same with other systems previously) but I sometimes search via company, to see if they support a particular system. For example I went to:
which says they have only one Starfinder product. If I follow the link though it takes me here:
Which clearly has 22 products available.
It seems unimportant maybe, but I may well not have opened that final page if I already had one Starfinder product from them.
