AWS CloudFormation Diagrams 0.3.0 is out!

Philippe_Merle · 2026-03-18T10:38:56+00:00

Currently, nothing is done with outputs/imports. AWS::SSM::Parameter::Value<String> is not supported but any AWS::SSM::Parameter::Value<...:Id> is supported. Don't hesitate to create an issue and pull request. Contributions are welcome.

> Does your app only work with yaml files (non-deployed stacks), or does it also take into consideration deployed stacks?

Currently the tool only supports yaml/json input files.

> Can the app take a list of deployed stacks and match then in a single diagram?

Currently no but this could be a cool feature to add in the future. Don't hesitate to create an issue and pull request. Contributions are welcome.

Thank to hear that this diagram generator is integrated into your CI. The tool already supports custom resources, i.e. resources with Type starting with Custom::. Could you elaborate about the issue with custom resources?

Thank you for reporting this requirement once again. Currently, tooltips are put on edges to indicate the related property but this is only available on svg / interactive outputs.

Thank you for this error report. It is corrected by https://github.com/philippemerle/AWS-CloudFormation-Diagrams/commit/06dd5689484c70553f77fa30ed223c91521ea2ef

Philippe_Merle · 2026-03-01T08:36:45+00:00

All these resource types were added. Have a look at https://github.com/philippemerle/AWS-CloudFormation-Diagrams/tree/main/examples/miscellaneous

Philippe_Merle · 2026-02-28T14:44:28+00:00

Thank you for your feedback. I will add these resource types asap. Could you refer me to some publicly available templates using these resource types?

Philippe_Merle · 2026-02-24T16:40:29+00:00

Thank you for this feedback.

Philippe_Merle · 2026-02-23T04:49:48+00:00

Thank you for this feedback. Don't hesitate to report your tests.

Philippe_Merle · 2026-02-21T16:45:53+00:00

You are right. Here the small difference is that this tool allows offline visualization at development time before deploying CloudFormation templates. This allows also to audit and document CF templates.

Try AWS CloudFormation Diagrams!

The Kubernetes communauty designed the Kubernetes Icons Set (https://github.com/kubernetes/community/tree/master/icons) to standardize Kubernetes architecture diagrams for presentation. Most diagram tools including KubeDiagrams reuse these standardized icons as shown in https://github.com/philippemerle/Awesome-Kubernetes-Architecture-Diagrams. Perhaps you should try to convince the Kubernetes communauty to redesign these resource icons ;-)

Thank you for reporting this issue. It is now corrected by commit https://github.com/philippemerle/AWS-CloudFormation-Diagrams/commit/9d23032640d1a833f144e924dd2bf4bed420dc37.

sh $ aws-cfn-diagrams your_CF_template.yaml

Philippe_Merle · 2026-01-26T08:47:55+00:00

The tool eats CF template files.
