TFLint
A Pluggable Terraform Linter.
Overview
TFLint is a framework and command-line tool for linting Terraform code. It focuses on checking for potential errors, enforcing best practices, and maintaining code quality, rather than just security. It has a pluggable architecture that allows for easy extension with custom rules and support for different cloud providers.
✨ Key Features
- Focus on linting for best practices and errors
- Pluggable architecture for custom rules
- Provider-specific rules (AWS, Azure, GCP)
- Fast and lightweight
- IDE integration (VS Code)
🎯 Key Differentiators
- Focus on correctness and best practices over pure security.
- Highly extensible with a plugin system.
- Deep inspection of provider-specific attributes (e.g., valid instance types).
Unique Value: A specialized linter that improves Terraform code quality by enforcing best practices and validating provider-specific settings.
🎯 Use Cases (4)
✅ Best For
- Automated checking of Terraform code for provider-specific best practices and potential errors.
💡 Check With Vendor
Verify these considerations match your specific requirements:
- Comprehensive security scanning (tools like Checkov or tfsec are better suited)
- Scanning non-Terraform IaC
🏆 Alternatives
While security scanners check for vulnerabilities, TFLint focuses on correctness and maintainability, catching issues that security tools might miss.
