How to create architecture diagrams from code (without hand-drawing)

Every architecture diagram starts accurate and ends fiction. The system ships, the boxes don't move, and three sprints later the diagram on the wiki describes a system that no longer exists. The fix isn't discipline — it's generating the diagram from the same source of truth that defines the system: your code and infrastructure-as-code.

Start from what already describes the system

Your docker-compose.yml, Kubernetes manifests, CloudFormation templates, and Terraform configurations already encode the components and their relationships. Architext parses them, extracts the resources and dependencies, and renders an editable diagram — so the picture is derived from reality, not redrawn from memory.

You can paste a file directly, or point Architext at a GitHub repository (public, or private when you sign in with GitHub) and let it scan for infrastructure-as-code.

Refine with an AI co-editor

Generated diagrams are a starting point. Describe changes in plain English — "add a Redis cache between the API and the database" — and the diagram updates atomically. Group by tier, drill into containers, and annotate with decisions and non-functional requirements.

Keep it a deliverable, not a screenshot

Because everything is a queryable graph, the same model compiles into a solution-architecture document and an audience-tailored slide deck. Export to PNG, SVG, Mermaid, or PowerPoint, or share a read-only link with your team.
