## What it is
tenv is a version manager written in Go for OpenTofu, Terraform, Terragrunt, Terramate, and Atmos. It detects required versions from HCL files, verifies download signatures, and works as standalone binaries across all major platforms.

## Use cases
- switch between terraform versions per project
- manage opentofu versions
- install terragrunt specific version
- detect required terraform version from hcl files
- replace tfenv and tofuenv with a faster cross-platform tool
- verify terraform binary signatures with cosign or pgp

## When to avoid
- you need a generic version manager for many unrelated tools
- you already standardize on asdf-vm with its plugin ecosystem
- you only ever use one pinned version of Terraform

## Facets
- artifact type: cli-tool
- maturity: active
- function: developer-tools, cli, version-control, configuration-management, security
- domain: infrastructure-as-code, developer-tools
- platform: windows, bsd, cli, cross-platform, go
- tags: terraform, opentofu, terragrunt, version-manager, iac, tfenv-successor, cosign, hcl-parsing, devops, command-line, linux, macos
