What it is

InfraSketch turns infrastructure-as-code into architecture diagrams in a browser, with options to export or share the result. It handles Terraform HCL and plan JSON, CloudFormation, CDK, Pulumi, Kubernetes, Terragrunt, Docker Compose, Bicep, and ARM. Its library covers more than 85 resource types across AWS, Azure, and GCP. Diagrams can be exported as PNG, SVG, draw.io XML, or Mermaid code, or shared by URL. Terraform project ZIP uploads can expand local modules, and public modules can be fetched from the Terraform Registry. For a selected resource, blast-radius analysis maps downstream effects and upstream dependencies. The site also describes Checkov security and Infracost cost overlays, alongside a GitHub Action, CLI, MCP server, and embeddable web component. InfraSketch says parsing and rendering happen client-side, without server processing, storage, telemetry, cloud credentials, or uploaded code; it can work offline after loading. The free plan costs nothing, with no signup and no limits, and the project is licensed under AGPL-3.0. Raw HCL does not evaluate count, for_each, or variables; the suggested workaround is Terraform plan JSON.
