It’s typically just a Facebook group of your neighbors, so “platform” might be a bit strong for what it is. Besides everything being free, I’ve found it helps build a bit of a sense of community for those who participate.
Ah gotcha, I heard about that, the founders sort of stepped back from the FB groups version and started trying to push a standalone app version. I'm guessing the FB groups version is still more popular/useful.
Oh, also, there're a lot of plants and things that get exchanged, another difference from second hand shops.
