I'm working on a local desktop app for inventory and production management: https://kitted.site

It includes bill of materials, purchase/production orders, "can I make n?", stock takes, multiple stock locations, and barcode scanning. It's aimed mainly at small business and makers for the time-being, but still allows multiple users to connect over the the local network.

Love seeing more local desktop apps in these threads, especially ones tackling local network sync like Kitted. I'm a solo dev also in the trenches building a local desktop tool right now, so I know how fun (and painful) those architecture choices can be. Would love to compare notes sometime if you're ever up to chat. Either way, the app looks super solid.
