Switch Terraform versions in seconds, not sprints.
Tfenv is a lightweight, fast, dependency-free Terraform version manager. Install any HashiCorp release, pin it per Infrastructure as Code (IaC) project, and eliminate version drift across laptops, CI runners, and production environments.
A specialized version manager built specifically for the Terraform CLI.
Tfenv solves the critical challenge of version drift in Infrastructure as Code by reading the version pin from your repository, downloading the matching HashiCorp-signed Terraform binary, and shimming it onto your PATH automatically. No more manual tarballs or "works on my machine" tunnels.
It operates identically on macOS, Linux, and Windows. This guarantees your onboarding documentation, CI/CD pipelines, and pair programming sessions all leverage the exact same IaC tooling surface, ensuring state file integrity and predictable provider behaviors.

Browse GuidesYou can install the Tfenv version manager by downloading the official archive and extracting it into your ~/.tfenv directory, then adding the bin folder to your system PATH. Alternatively, macOS users can install it via Homebrew using brew install tfenv.
On Windows, you can extract the Tfenv version manager into your %USERPROFILE%\.tfenv directory using PowerShell. You must then manually add the .tfenv/bin directory to your Windows PATH environment variables to use the tfenv command for Infrastructure as Code automation.
No, Tfenv is designed to be completely dependency-free. It is built as a POSIX-compliant shell script. As long as your system has a standard shell environment (like Bash or Zsh) and curl or wget for downloading HashiCorp binaries, Tfenv will run perfectly.
You can download the latest master branch directly as a zip archive from the official source. Extract it and place the contents in your target installation directory to start managing your Infrastructure as Code versions.
Yes, Tfenv has an official Homebrew formula. You can install it on macOS by running brew install tfenv. This is the fastest and most maintainable installation method for Mac users managing Terraform CLI versions.
To pin a version, navigate to your Infrastructure as Code project root and run tfenv pin <version>. Alternatively, manually create a .terraform-version file containing the exact version number. Tfenv will automatically use this version whenever you enter the directory.
Yes. Tfenv supports monorepos by walking up the directory tree. You can place .terraform-version files in different subdirectories. When you cd into a specific service's folder, Tfenv reads the nearest pin file and switches versions instantly.
The .terraform-version file is a simple text file containing the exact Terraform CLI version your project requires. Tfenv reads this file automatically to download, install, and shim the correct binary without manual intervention.
You can switch versions by running tfenv use <version>. If the version is already installed locally, Tfenv will switch to it immediately. If it is not installed, Tfenv will prompt you to run tfenv install first.
Yes, Tfenv can install pre-release versions like alphas, betas, and release candidates. Simply run tfenv install latest:^1.10 or specify the exact pre-release string like tfenv install 1.10.0-rc1.
To use Tfenv in CI/CD pipelines, add a step to install Tfenv via download, then run tfenv install. To speed up pipelines, cache the ~/.tfenv directory using your CI provider's caching mechanism so binaries are downloaded only once.
Yes, in GitLab CI, you can use the cache keyword with a key pointing to your .terraform-version file. Configure the cache paths to include the ~/.tfenv/versions directory to prevent re-downloading the HashiCorp binaries on every pipeline run.
Always commit the .terraform-version file to your repository. This ensures that both local developers and CI/CD runners use the exact same Terraform CLI version, preventing state file corruption and unpredictable provider behaviors.
Yes, Tfenv is lightweight and works perfectly in Docker containers, including Alpine Linux. You just need to install standard shell utilities (bash, curl, tar) in your Dockerfile before running the Tfenv installation script.
You can set TFENV_TERRAFORM_VERSION to bypass reading the .terraform-version file, and TFENV_AUTO_INSTALL=true to allow Tfenv to automatically download the required version without interactive prompts, which is ideal for CI runners.
Tfenv automatically downloads the SHA256SUMS file published by HashiCorp alongside the Terraform release. It verifies the checksum of the downloaded zip file against this list to ensure the binary has not been corrupted during download.
Yes. You can point the TFENV_REMOTE environment variable to an internal HTTP server or artifact repository (like Artifactory or Nexus) hosting the Terraform binaries and checksums.
Export the TFENV_REMOTE environment variable with the base URL of your internal mirror (e.g., export TFENV_REMOTE='https://internal-mirror.corp.com/tf'). Tfenv will append the specific version paths to this base URL.
By default, Tfenv performs SHA256 verification. For strict enterprise GPG signature verification, you can provide your own HashiCorp GPG public key by configuring the TFENV_GPG_KEYRING environment variable.
Yes. Tfenv does not phone home, collect telemetry, or require external runtimes. It simply wraps HashiCorp's official binaries in a localized user directory, making it compliant with strict enterprise security policies.
This usually happens if your shell PATH is pointing to a system-installed Terraform rather than Tfenv's shim. Ensure ~/.tfenv/bin is prepended to your PATH at the very beginning of your shell configuration file.
To uninstall a version, run tfenv uninstall <version>. Tfenv will refuse to uninstall the currently active version unless you pass the --force flag, which prevents accidental removal during an active deployment.
If you are behind a corporate proxy, set the standard HTTPS_PROXY and HTTP_PROXY environment variables. If the proxy uses a custom CA certificate, point TFENV_CURL_OPTIONS to the certificate bundle.
If you installed via direct download, simply download the latest archive and replace the existing files. If you used Homebrew, run brew upgrade tfenv. This ensures you have the latest features and support for new Terraform releases.
By default, the Tfenv script is stored in ~/.tfenv. The downloaded Terraform binaries are stored in ~/.tfenv/versions/<version>, and the active shim is symlinked in ~/.tfenv/bin. You can change this using the TFENV_ROOT variable.
