Documentation: https://tfmate.readthedocs.org

tfmate is a command line interface and Python library for analyzing Terraform configurations and state files. It provides powerful tools for understanding your infrastructure as code, including configuration analysis, AWS service discovery, and state file inspection.

Features

• Configuration Analysis: Analyze Terraform configuration files to understand providers, backends, and version constraints
• AWS Service Discovery: List and filter AWS services from botocore definitions
• State File Inspection: Extract Terraform version and metadata from state files
• Multiple Output Formats: Support for JSON, table, and text output formats
• Flexible Configuration: Customizable through configuration files and environment variables

Installation

tfmate supports Python 3.10+.

To install from PyPI:

pip install tfmate

To install using uv:

    sh -c "$(curl -fsSL https://astral.sh/uv/install)"
    uv tool install tfmate

Ensure you have ./local/bin in your PATH, since that's where uv puts the executable.
