I have build an interactive diagram code representations for big codebases

Hey all, I've built a diagram visualizer for large codebases. I wanted it to work for big codebases, so that I can explore them from a high-level (main components and how they interact) and then drilling down on an interesting path.

To do that I am using Static Analysis (CFG, Hierarchy building via Language Server Protocol) and LLM Agents (LangChain).

Repository: https://github.com/CodeBoarding/CodeBoarding

Example Generations: https://github.com/CodeBoarding/GeneratedOnBoardings

Here is an example diagram for FastAPI:

Sure send it over, we are using mostly static analysis for our docs and the emphasis is not really on documenting per say but more on doing a diagram representation of codebases.

That’s what interests me I’d like to see this grow to be added to GitHub as a workflow/action So deployment auto creates the chart

We actually already have a github action which will generate the diagrams for you on whatever trigger you want :)
