SchematIaC Docs Your Terraform and Bicep, as a drawing
SchematIaC is a VS Code extension that opens your Terraform (.tf, .tfvars) or Azure Bicep (.bicep, .bicepparam) files on one canvas, shows what every value actually resolves to, and writes your changes back into the files as clean one-line diffs — comments, alignment and ordering untouched. Everything runs inside VS Code; your code never leaves your machine.

SchematIaC works with Terraform (and OpenTofu — same HCL) and Azure Bicep. It needs VS Code 1.74 or newer, and no terraform or bicep binary.
