Application Code Assessment for dependency analysis

Hi All,

I am looking for guidance/ inputs in selecting an opensource tool for assessment of application software (multi program language supported) by scanning code from Git repos to derive dependencies in terms of connectivity in multi-tier architecture (between web-app-db, caching, message broker, external integrations etc.). Idea here is to prepare target AWS architecture + migration approach based on assessment report. Appreciate if anybody has any suggestion on tool or how to handle assessment?

Thanks.
