ArchMap

ArchMap scans a GitHub organization, extracts service topology from source code without running anything, and serves an interactive architecture graph in the browser.

It reads source files statically — no Docker, no databases, no running services required.

Language support

Language	Framework	Status

What it produces

• Service Flow — which services depend on which, with Kafka topic edges
• Data Flow — shared data types (entities, DTOs, events) mapped to the services that produce and consume them
• Function Flow — public service methods with cross-service call edges drilled in

How to use it

Method	When to use
GitHub Action	Automate scanning in CI, deploy graph to GitHub Pages

Quick example

- uses: abdullahbodur/archmap@main
  with:
    github_token: ${{ secrets.ORG_TOKEN }}
    github_org: your-org
    output_path: _site

The action scans your org, builds the graph, and writes a static site to _site/ ready for GitHub Pages.
