Both — Architext auto-detects CloudFormation in either format.

Can it read nested references?

Resource references (Ref/GetAtt-style dependencies) become edges so the structure is explicit.

What a good CloudFormation diagram shows

A useful CloudFormation diagram surfaces the resources a stack creates and the references between them (a function's role, a service's queue), grouped so the architecture — not the raw template — is legible.

How Architext builds it

Paste a CloudFormation template (JSON or YAML) or import a repo; Architext auto-detects the format, extracts resources and references, and lays out the diagram.

Document, export, and share

Once the diagram is right, compile a solution-architecture document, generate an audience-tailored slide deck, export to PNG, SVG, Mermaid, or PowerPoint, or share a read-only link — all from the same CloudFormation model.

FAQ

JSON or YAML?: Both — Architext auto-detects CloudFormation in either format.
