No more diagram_v3_FINAL.png. Version control your architecture with Mermaid & PlantUML in Git. Full history, diffs in PRs, and rollback.
Sound familiar? File-based diagrams lead to naming chaos, lost versions, and no way to see what actually changed.
With image-based diagrams, there's no attribution. No blame, no commit messages, no PR context for why a change was made.
The silent killer: an architecture diagram that looks authoritative but hasn't been updated in six months.
Impossible to answer with PNG exports. With versioned diagrams, it's a simple git log or diff command.
Treat architecture diagrams like code — because they are.
Every architectural decision is tracked. See who added a service, when a database was removed, or why an API endpoint changed.
Architecture changes appear as text diffs in PRs. Reviewers see exactly what components or relationships changed.
Propose architecture changes on a feature branch. Review, discuss, and merge — same workflow as code changes.
git blame shows who changed every line of the diagram and when. Link to the PR or issue that motivated the change.
If a diagram change was wrong, git revert it. No hunting for old PNG exports or asking "does anyone have the previous version?"
CI/CD renders diagrams on every merge. Documentation is always up to date. No manual export step.
