Our verdict on InfraSketch
InfraSketch converts infrastructure-as-code into architecture diagrams in a web browser. It is aimed at DevOps, SRE and cloud infrastructure teams that need to visualize AWS, Azure or Google Cloud resources from code rather than draw environments manually. The tool supports eight IaC formats, including Terraform, CloudFormation, CDK, Pulumi, Kubernetes, Terragrunt and Docker Compose. Automatic resource grouping, containment mapping and connection routing organize the resulting diagrams, while an interactive drag-and-drop editor supports further changes.
Its strongest differentiator is the depth around infrastructure understanding. Terraform module expansion and registry module fetching can extend the source context, while dependency and blast-radius analysis helps show the likely scope of infrastructure changes. Checkov security overlays and Infracost cost overlays add operational context to the diagram. Exports include PNG, SVG, draw.io XML and Mermaid code, and integrations cover AWS, Azure, Google Cloud, Terraform, GitHub Actions, Claude Code and Cursor. These capabilities make InfraSketch more than a static architecture drawing tool for teams working directly from infrastructure definitions.
The Free plan costs 0, requires no signup, has no limits, is open source and runs in the browser. Client-side processing means code is handled without cloud credentials or data upload. That model suits teams seeking a local-processing workflow and a tool they can inspect or adapt. InfraSketch is a strong fit when IaC visualization, impact analysis, security context and export flexibility matter most. Teams seeking a clearly AI-driven diagram generator, a native desktop or non-browser workflow, or a broader collaboration platform should consider alternatives focused on those needs.
