I myself had been looking to create my own app for a long time, but getting the data you want easily from a single source wasn't as easy as it should be. With this tool, you can easily create your own PostgreSql or Mongo databases in a single command. If you don't like the schema, or want to use the engine to populate a different database, you can implement an interface and the Engine will do it for you (the app is built with netcore 2.2)

Here's the repository page, which includes all the instructions to get the program, along with API documentation for the CLI commands:

For quick reference, the Engine provides data such as player information (names, draft profiles, college, etc), teams, every important stat type for players and teams (from 2010 to the present), and weekly matchups.

I have it released in an alpha state right now, although it's pretty much feature-complete. I'm open to feedback on the database schemas I've created for PG/Mongo. Would love to hear any thoughts, ideas, or recommendations from the community. Have fun and cheers!
