AI diagram generators
AI diagram generators, one per diagram type.
The agent emits a semantic graph and ELK computes the layout, so overlapping boxes are structurally impossible.

- AI Architecture Diagram GeneratorDescribe the system, or point it at the repository and let it find out for itself.
- AI System Design Diagram GeneratorFor a design doc, a review, or the whiteboard round where you have forty minutes and need the shape to be right.
- AI Sequence Diagram GeneratorFor when the question is not what the components are but in what order they talk, and what happens when step four fails.
- AI ER Diagram GeneratorPoint it at the schema you already have. The relationships are declared, so the diagram is a rendering rather than an interpretation.
- AI Data Flow Diagram GeneratorWhere the data comes from, what transforms it, where it lands, and which of those crossings leave your control.
- AI C4 Model Diagram GeneratorOne system, drawn at three levels of zoom, so each diagram has one audience instead of trying to serve all of them.
- AI Flowchart GeneratorFor a process with decisions in it, where the question is what happens next rather than what talks to what.
- AI UML Diagram GeneratorIn practice teams use about four of UML's fourteen diagram types, and this draws those four properly rather than all of them badly.
- AI Cloud Architecture Diagram GeneratorRead your infrastructure as code and draw it, with the real service names and no cloud credentials required.
- AI AWS Architecture Diagram GeneratorFrom the Terraform you already have, with no read-only role to provision and nothing sent anywhere.
- AI Azure Architecture Diagram GeneratorFrom Bicep, ARM or Terraform, without granting a reader role on the subscription.
- AI GCP Architecture Diagram GeneratorFrom the Terraform in your repository, with no project access and nothing uploaded.
- AI Kubernetes Architecture Diagram GeneratorThe topology is in the YAML. It is just spread across forty files and expressed as label matches.
- AI Microservices Diagram GeneratorThe interesting question is never how many services there are, it is which ones cannot be deployed without the others.
- AI Database Schema Diagram GeneratorThe physical view: tables, columns, keys and indexes, for when you need what is actually stored rather than the conceptual model.
- AI Infrastructure Diagram GeneratorWhere things run, what can reach what, and which boundaries the traffic crosses on the way.
Elsewhere
- System Design TemplatesEach template is a real diagram produced by the same layout engine the app runs, not a picture of one.
- AI System DesignThe diagram can cause the code, not just describe it.
- Harness EngineeringAgent equals model plus harness. The harness is the half you can actually change.
- Coding Engines Lucid Train Can DriveThe binary is already on your machine and already signed in. Nothing is proxied and no credential passes through us.
- Dependency and Agent Supply Chain AuditYour packages are audited by everyone. The programs your agent launches are audited by almost no one.
- Grafana and Observability in a Coding AgentNothing is exported to us. It reads the Grafana you already run, with your credential, on your machine.
- AI Design Mode for Web PagesRunning on the Claude Code or Codex CLI you already have, with your repository open beside it.
- Software Architecture GlossaryWhat each term means, where it came from, and where it stops being useful.
- Guides to Choosing Architecture ToolsNo winner is declared, because the right answer depends on constraints a web page cannot see.
- Alternatives to Popular Diagramming and Agent ToolsEach page sorts the field by the reason you are leaving, because that is what decides the answer.
- MCP and Architecture DiagramsYour agent supplies the structure. A constraint solver decides where everything goes.
- Generate a Diagram from Your CodeEvery source below lists the exact files it reads and the constructs it maps to diagram nodes.
- Compare Lucid TrainEvery page says what the other tool is better at. If that section were empty the comparison would not be worth reading.
- Convert Code and DiagramsEvery conversion page states what survives the round trip and what does not.
- Use CasesEach page includes who it is not for, which is usually the more useful half.
- Beyond DiagramsDiagrams are the front door. These are the rooms behind it.
