Install the CLI

The dnsid CLI is the Developer Kit’s command-line tool: identity provisioning, record inspection and verification, token minting, and the DNSid Local environment. It is free to use and distributed as prebuilt binaries, with the source coming soon. The open-source SDKs do not depend on it, but it is the fastest way through the quickstart.

Install with a package manager

brew install dnsid-ai/tap/dnsid

Installs from the dnsid-ai/homebrew-tap cask on macOS (Apple Silicon and Intel) and Linux (amd64 and arm64).

scoop bucket add dnsid https://github.com/dnsid-ai/scoop-bucket
scoop install dnsid

Installs from the dnsid-ai/scoop-bucket manifest (Windows x64).

curl -fsSL https://docs.dnsid.ai/install.sh | sh

The script detects your platform, downloads the current release archive, verifies it against that release’s SHA256SUMS, and installs dnsid into the first of ~/.local/bin, /usr/local/bin, or ~/bin that is writable and already on your PATH (falling back to ~/.local/bin). It never installs a file that fails verification.

Check the install with dnsid --version.

Upgrade and uninstall

Use the same channel you installed with. which dnsid (or where dnsid on Windows) shows which binary is on your PATH; if you have installed more than one way, which -a dnsid lists them all and PATH order decides which one runs.

brew upgrade dnsid
brew uninstall --cask dnsid
brew untap dnsid-ai/tap      # optional: remove the tap too

scoop update dnsid
scoop uninstall dnsid
scoop bucket rm dnsid        # optional: remove the bucket too

To upgrade, run the install command again. It fetches the current release, verifies it, and replaces the binary in place.

To uninstall, delete the binary from wherever the script put it:

rm "$(which dnsid)"
