Installation

Install the Nullify CLI to manage your security posture from the command line

Quick Install

Run the install script to download the latest Nullify CLI binary:

curl -sSfL https://raw.githubusercontent.com/Nullify-Platform/cli/main/install.sh | sh -s -- --host api.<TENANT>.nullify.ai

Replace <TENANT> with your organization name (e.g. api.acme.nullify.ai).

The curl | sh installer runs on macOS and Linux. It does not run on native Windows — use WSL or Git Bash, or follow the Manual Installation steps with the Windows archive below.

This will:

• Detect your OS and architecture (macOS, Linux; amd64, arm64)

• Download the latest release from GitHub Releases

• Verify the SHA256 checksum

• Install the binary to /usr/local/bin/nullify (or ~/.local/bin/)

• Configure the CLI to connect to your Nullify instance

Manual Installation

Download the latest archive for your platform from GitHub Releases:

Platform	Architecture	Archive
macOS	Apple Silicon (arm64)	nullify_darwin_arm64.tar.gz
macOS	Intel (amd64)	nullify_darwin_amd64.tar.gz
Linux	amd64	nullify_linux_amd64.tar.gz
Linux	arm64	nullify_linux_arm64.tar.gz
Windows	amd64	nullify_windows_amd64.zip

After downloading:

tar -xzf nullify_<os>_<arch>.tar.gz
sudo mv nullify /usr/local/bin/nullify

With Go

If you have a Go toolchain installed, you can build and install the CLI directly:

go install github.com/nullify-platform/cli/cmd/cli@latest

Verify Installation

nullify --version

Configuration

The CLI resolves which Nullify instance to connect to in this order:

1. The --host flag

2. The NULLIFY_HOST environment variable

3. The host saved in ~/.nullify/config.json by nullify auth login

# 1. Set via flag (highest priority)
nullify --host api.<TENANT>.nullify.ai <command>

# 2. Or set via environment variable
export NULLIFY_HOST=api.<TENANT>.nullify.ai
nullify <command>

NULLIFY_HOST (and --host) accept either the full API host api.<TENANT>.nullify.ai or the bare <TENANT>.nullify.ai form. The CLI stores the host in its bare <TENANT>.nullify.ai form and adds the api. prefix automatically when it makes API requests, so either form works.
