A buddy and I have created a "companion" website for MLB The Show.
Website: https://www.theshowbase.com/
Android app: https://play.google.com/store/apps/details?id=com.theshowbase
Platform: Web/App
Code: Nextjs/Python
Functions: Database, prices, team builder, mini games (bingo, pack opener, grand slam guess, etc) and much much more.
We are proud of the work so far, and keep adding features, tools and similar - You are more than welcome to post any feedback or specific request.
As a side note I think our team builder is the best there is out there
