Look I got a bunch of once-a-week tools and a bunch of once-a-year tools, and even once-ever tools (looking at you, wrench that removes drains from bathtubs).
I want to put all my TOOLS in an app or database that i'm comfortable sharing. Then define those groups - church people, work people, neighbors whatever. Then they can do the same, and say which group can borrow what. And do requests, sign outs, whatever.
But this could be huge. Because women especially will lend clothing, accessories, purses whatever to their friends. Christmas party coming up? Let me double check my friend's closet library. Stop fast-fashion, share!
Does anything like this exist? It seems perfect for many applications. Books, DVDs whatever! And you could add items with a picture, but also import from URL like amazon or whatever-- the way MEALIE scrapes recipes.
I use Trello, which isn't at all self hosted but it's free and ready to go.
