How do I store diagrams in Git?

Use text-based diagram formats like Mermaid (.mmd) or PlantUML (.puml). These are plain text files that Git can diff, merge, and version like any other source file. Mermaid code blocks also render natively in GitHub and GitLab Markdown.

Does GitHub render Mermaid diagrams?

Yes. GitHub renders Mermaid code blocks (```mermaid) natively in Markdown files, issues, pull requests, and wikis. No extensions or plugins needed. GitLab also supports Mermaid rendering.

Can AI help create diagrams for Git?

Yes. Cybewave generates Mermaid and PlantUML code from plain English descriptions. Copy the generated code into your repository files. The AI handles syntax while you focus on architecture decisions.

Diagrams that live in your repo

Architecture diagrams belong next to your code — in Git, versioned, and reviewable. Mermaid renders natively on GitHub & GitLab. AI generates the code for you.

Why diagrams belong in Git

Your code lives in Git. Your infrastructure-as-code lives in Git. Your CI/CD configuration lives in Git. Why do your architecture diagrams live on someone's Google Drive?

When diagrams are stored as Mermaid or PlantUML code in your repository, they get all the benefits of Git: version history, branching, merging, code review, blame, and CI/CD integration. They're discoverable, searchable, and always next to the code they describe.

Cybewave Studio generates Mermaid & PlantUML code from plain English — commit the output to your repo and your architecture-as-code workflow is complete.

How it works

From AI generation to Git repository in four steps.

Generate diagram code

Describe your architecture in Cybewave and get Mermaid or PlantUML code. Copy the text output.

Commit to your repo

Add .mmd or .puml files to your repository, or embed Mermaid blocks in README.md and docs.

Review in pull requests

Architecture changes show as text diffs. Mermaid renders in GitHub/GitLab Markdown preview.

Auto-render in CI/CD

Use Mermaid CLI or PlantUML server in your pipeline to generate PNG/SVG on every merge.

Benefits of Git-based diagrams

Everything you love about Git, applied to architecture.

Single source of truth

Code and architecture in the same repo. No external tools, no separate permissions, no out-of-sync documentation.

GitHub/GitLab native rendering

Mermaid code blocks render as diagrams directly in README files, issues, PRs, and wikis. No plugins needed.

Same workflow as code

Branch, commit, push, PR, review, merge. Architecture follows the exact same workflow your team already uses for code.

Discoverable and searchable

grep for components, relationships, or services across all diagrams. Find every diagram that references "auth-service" instantly.

Works with mono and poly repos

Store diagrams in /docs, alongside each service, or in a dedicated architecture repo. Fits any repository strategy.

Free and open format

Mermaid and PlantUML are open source. No vendor lock-in, no subscription required to view your own diagrams.

Mermaid in your README

GitHub and GitLab render Mermaid natively in Markdown.

# System Architecture
