Architecture Diagrams That Never Go Stale
DiagramGuru is an AI Agent that watches your repository, reads your code, and autonomously generates up-to-date architecture diagrams on every commit — running inside your own GitHub Actions with zero manual effort.
Diagrams drift the moment you stop maintaining them.
Architects spend hours redrawing diagrams after every sprint. Teams reference outdated Confluence pages. New engineers make wrong assumptions. DiagramGuru eliminates this cycle by making your code the single source of truth.
Everything an Architect Needs
Built around the real-world challenges of maintaining living architecture documentation.
Always Up-to-Date Diagrams
Architecture diagrams are automatically regenerated whenever your code changes — no more stale, out-of-sync documentation.
Keep Your Team Aligned
Every architect, developer, and stakeholder stays in sync. Diagram changes are versioned alongside your code and visible to the whole team.
Code is the Source of Truth
Diagrams are derived directly from your codebase, not maintained in a separate tool. If the code changes, the diagram changes.
Runs in Your GitHub Actions
Diagram generation runs inside your own CI/CD pipeline. Your source code never leaves your infrastructure — you stay in full control.
Bring Your Own AI Key (BYOK)
Connect your own OpenAI, Gemini, or Anthropic API key. No data is sent to our servers — your architecture stays private.
Enterprise-Grade Privacy
Zero vendor lock-in on your AI provider. Swap keys, change models, or rotate credentials at any time without touching the workflow.
How It Works
Set up once, benefit forever.

Your AI Key. Your Data. Your Control.
DiagramGuru never stores or proxies your source code. Supply your own OpenAI, Google Gemini, or Anthropic API key — the diagram generation runs inside your GitHub Actions, meaning your proprietary architecture never touches our servers.
