Made a tool for generating diagrams of your codebase

  After seeing some really cool tools that build high-level overview diagrams of a repo, we wanted to see if we could create a tool for building any diagrams from a codebase (for the diagrams we support, which are architecture, ERD / schema, flow charts, and sequence diagrams).

  Try it out on any public Github repo! A few notes: 1) Works best if you are pretty explicit with the prompt. We're only offering 2 free runs right now because of the expense involved. We have some examples built in and I've left a couple links below. 2) Works best on repos of a few hundred files or low thousands. More than that and it really helps if you can provide some explicit instructions on where to look. 3) The feature that links to specific code files is pretty fun.

  Here a some examples:

  Supabas real time updates: https://eraser.io/git-diagrammer?diagramId=2XXiOvPfJjtfMbWdM... Subase realtime architecture: https://eraser.io/git-diagrammer?diagramId=nIvgs2dMvarCYJ8zV... Primsa migrations: https://www.eraser.io/git-diagrammer?diagramId=uK7UptrWd4EEY...
