## Tools

The following tools help improve code quality and automation of Terraform configurations on AWS, as recommended in this best practices guide.

Code quality:
+ [Checkov](https://www.checkov.io/): Scans Terraform code to identify misconfigurations before deployment.
+ [TFLint](https://github.com/terraform-linters/tflint): Identifies possible errors, deprecated syntax, and unused declarations. This linter can also enforce AWS best practices and naming conventions.
+ [terraform-docs](https://github.com/terraform-docs/terraform-docs): Generates documentation from Terraform modules in various output formats.

Automation tools:
+ [HCP Terraform](https://www.terraform.io/cloud): Helps teams version, collaborate, and build Terraform workflows with policy checks and approval gates.
+ [Atlantis](https://www.runatlantis.io/): An open source Terraform pull request automation tool for validating code changes.
+ [CDK for Terraform](https://developer.hashicorp.com/terraform/cdktf): A framework that lets you use familiar languages such as TypeScript, Python, Java, C\#, and Go instead of HashiCorp Configuration Language (HCL) to define, provision, and test your Terraform infrastructure as code.
