TFLint is a pluggable linter for Terraform that finds possible errors, deprecated syntax, and unused declarations, and enforces best practices and naming conventions. It works as a framework where provider-specific rules (AWS, Azure, GCP) are supplied via plugins.

Use cases

• lint terraform code for errors before apply
• catch invalid aws instance types in terraform
• enforce naming conventions in terraform modules
• warn about deprecated terraform syntax
• find unused declarations in terraform files
• add terraform linting to ci pipeline

When to choose

• you write or review Terraform and want static analysis beyond terraform validate
• you need provider-aware checks for AWS, Azure, or GCP resources
• you want to enforce team conventions via custom rules or plugins

When to avoid

• you use non-Terraform IaC tools like Pulumi or CloudFormation
• you only need basic formatting (terraform fmt covers that)
• you need policy-as-code across multiple IaC tools (consider OPA/Sentinel)
