I'm an indie gamedev and I got tired of searching through a bunch of different sites like SteamDB, TwitchTracker, VG Insights, etc. to do market research on games. So I started working on Perch to aggregate all this data in one place. Kind of like Ahrefs for games!Thought it was important to open-source the backend, because a lot of useful game data like game sales can only be roughly approximated so it's helpful to understand how the numbers are calculated.
