Arcobay vs Swimm
Swimm focuses on doc sync to code. Arcobay goes further.
We own visual architecture and decisions on the diagram — not just inline code documentation.
Key differences
What Arcobay adds beyond Swimm.
- Architecture diagrams generated from your repo, not hand-maintained doc snippets
- Decision notes attached to diagram nodes with history and tags
- Living doc sync commits ARCHITECTURE.md and PNG when architecture drifts
- Presentation video, Q&A, and onboarding built on the same living diagram
