HobbyDB is a platform that allows collectors and enthusiasts to research, document, and showcase their prized possessions. It allows users to upload images and record data about their own collectibles to keep track of them. There is also a marketplace where users can list their items for sale with just a few clicks, build wish lists, and receive alerts when stuff they want to buy goes up for sale. HobbyDB was founded in 2014 and is based in Boulder, Colorado.
