Terraform IaC Validator
Interactive Terraform template editor with real-time HCL parsing, infrastructure validation, and visual architecture diagram generation. Edit AWS resource definitions and see the planned infrastructure rendered instantly — the same IaC review workflow used at Kiwibank and Rapid7 for cloud deployments.
Getting Started • The editor loads a production-grade Terraform template for AWS infrastructure • Read the HCL code — it defines a VPC, subnets, load balancer, ECS cluster, and RDS database Interact • Click 'Validate & Plan' to parse the template and generate the infrastructure diagram • Edit the Terraform code directly — add resources, remove blocks, change configurations • Try removing the 'storage_encrypted' line from the RDS block and re-validate to see a security warning • Try adding a new aws_s3_bucket resource and watch it appear in the diagram Observe • The infrastructure diagram renders all parsed AWS resources with proper visual hierarchy • Validation output shows errors (red), warnings (orange), and passed checks (green) • Resource connections are drawn based on actual Terraform references in the code

The Problem: Infrastructure Drift and Blind Deployments
Manual cloud infrastructure provisioning — clicking through the AWS Console or running ad-hoc CLI commands — creates configuration drift. In projects GoTech worked with, the production AWS environment had no documentation, no version control, no reproducibility. Rebuilding the infrastructure from scratch would have taken weeks of archaeology.
Infrastructure as Code eliminates this by treating cloud resources the same way we treat application code: versioned, reviewed, tested, and automated.
Terraform Template Validation
This tool implements the review stage of an IaC workflow — the same validation performed during terraform plan and code review:
- Syntax Parsing: HCL blocks are parsed to extract resource types, names, and configurations.
- Reference Resolution: Cross-resource references (e.g.,
aws_vpc.main.id) are validated against the resource graph. - Security Audit: Configurations are checked against cloud security best practices — encryption at rest, restricted security group rules, multi-AZ deployments.
- Architecture Visualization: The planned infrastructure is rendered as a visual diagram, making it easy to verify the topology before applying changes.
Real-World Application
At Kiwibank, Terraform managed the entire AWS footprint — VPCs, ECS clusters, RDS instances, and the ALB configuration. Every infrastructure change went through a PR review with terraform plan output. At Rapid7, the threat intelligence platform’s cloud infrastructure was codified in Terraform modules, enabling reproducible deployments across staging and production environments.
Security-First Validation
The validator checks for common misconfigurations that cause real security incidents:
- Unencrypted storage — RDS without
storage_encrypted = true. - Overly permissive security groups — SSH (port 22) open to
0.0.0.0/0. - Single-AZ databases — No
multi_azfor production workloads. - Missing tags — Resources without proper environment and project tagging.
