## What it is
Terraformer is a Go CLI tool that generates Terraform configuration (tf/) and tfstate files from existing cloud infrastructure, effectively performing 'reverse Terraform' (infrastructure to code). It supports many providers including GCP, AWS, Azure, Kubernetes, Cloudflare, GitHub, and various monitoring services.

## Use cases
- generate terraform files from existing infrastructure
- import existing cloud resources into terraform state
- reverse engineer terraform configs from gcp project
- convert aws infrastructure to terraform code
- bootstrap terraform for an unmanaged cloud environment
- export kubernetes resources as terraform hcl

## When to choose
- you need to bring existing infrastructure under Terraform management
- you want to generate baseline HCL/tfstate from a live cloud account
- you need multi-provider import coverage (GCP, AWS, Azure, etc.)

## When to avoid
- you need ongoing support or security patches - the project was archived and deprecated as of March 2026
- you want actively maintained import tooling - consider alternatives like terraform's built-in import blocks or community forks
- you need Cloudflare support - it is documented as broken
